Machining Specifcations

O-Ring Gland Types

O-rings are primarily used to prevent the loss of a fluid or gas However O-rings can be used asdust seals drive belts or on rotating shafts Most O-ring seals can be classified into one of the threearrangements shown below

Whereas the ID or OD of the O-ring for a design is significantly influenced by the diameter of themating components (pistonrod and bore) the cross-section of the O-ring is usually fairly arbitraryThe following table describes some of the advantages when opting for a small cross-section or alarge cross-section

Selecting an O-Ring Cross-Section

Piston Configuration Rod Configuration

Face Type Configuration

bull More compactbull Lighter weightbull Less expensive especially for higher cost

elastomers like FKM or fluorosiliconebull Less machining required for machined grooves

since grooves are smallerbull More resistant to explosive decompression

bull Less prone to compression setbull Less volume swell in liquid on a percentage

basisbull Allows for larger tolerance while still

maintaining acceptable compression squeezeand compression ratio over full stack-up range

bull Less prone to leakage due to contaminationdirt lint scratches etc

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are

ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)

Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

Rod Type sealExtrusion Gap = Bore 983088- Rod 983088

There are different methods to counter O-ring

extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference

For hydraulic and pneumatic piston sealing applications

The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range

and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance

For hydraulic and pneumatic rod sealing applications

The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside

diameter interference

For hydraulic and pneumatic static axial sealing applications

An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following

housing dimensions apply

Reduction in Cross-Section

Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch

Compression

The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

HCS

Compression Squeeze

Compression Squeeze = CS - H

This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures

Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling

Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces

Thermal Degradation

Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed

Contributing Factors Rapid pressure changes Low-

modulus hardness elastomer

Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)

Explosive Decompression

Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable

only by measurement of physical properties

Machining Specifcations

O-Ring Gland Types

O-rings are primarily used to prevent the loss of a fluid or gas However O-rings can be used asdust seals drive belts or on rotating shafts Most O-ring seals can be classified into one of the threearrangements shown below

Whereas the ID or OD of the O-ring for a design is significantly influenced by the diameter of themating components (pistonrod and bore) the cross-section of the O-ring is usually fairly arbitraryThe following table describes some of the advantages when opting for a small cross-section or alarge cross-section

Selecting an O-Ring Cross-Section

Piston Configuration Rod Configuration

Face Type Configuration

bull More compactbull Lighter weightbull Less expensive especially for higher cost

elastomers like FKM or fluorosiliconebull Less machining required for machined grooves

since grooves are smallerbull More resistant to explosive decompression

bull Less prone to compression setbull Less volume swell in liquid on a percentage

basisbull Allows for larger tolerance while still

maintaining acceptable compression squeezeand compression ratio over full stack-up range

bull Less prone to leakage due to contaminationdirt lint scratches etc

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are

ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)

Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

There are different methods to counter O-ring

extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference

For hydraulic and pneumatic piston sealing applications

The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range

and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance

For hydraulic and pneumatic rod sealing applications

The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside

diameter interference

For hydraulic and pneumatic static axial sealing applications

An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following

housing dimensions apply

Reduction in Cross-Section

Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch

Compression

The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

HCS

Compression Squeeze

Compression Squeeze = CS - H

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces

Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression

Suggested solutions Gland design should take into

account material responses to chemical and thermalenvironments

Over-Compression

Description The seal exhibits cuts or marks which spiralaround its circumference

Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness

elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication

Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings

Spiral Failure

Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered

Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing

Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings

Extrusion (andor Nibbling)

Common O-Ring Failures

8142019 O Ring Brochure

Description The seal exhibits a flat-sided cross-section theflat side corresponding to the mating seal surfaces

Contributing Factors Excessive compression Excessivetemperature Incompletely cured elastomer Elastomer withhigh compression set Excessive volume swell in chemical

Suggested Solutions Low compression set elastomerProper gland design for the specific elastomer Confirmmaterial compatibility

Compression Set

Description The seal or parts of the seal may exhibit smallcuts nicks or gashes

Contributing Factors Sharp edges on the glands orcomponents Improper sizing of elastomer Low-modulus

hardness elastomer Elastomer surface contamination

Suggested Solutions Remove all sharp edges Propergland design Proper elastomer sizing Higher-modulushardness elastomer

Installation Damage

Description The failure is often very difficult to detect fromexamination of the seal The seal may exhibit a decrease incross-sectional size

Contributing Factors Improper or improperly curedelastomer High vacuum levels Low hardnessplasticizedelastomer

Suggested Solutions Avoid plasticized elastomers Ensure

all seals are properly post-cured to minimize outgassing

OutgassingExtraction

httpslidepdfcomreaderfullo-ring-brochure 3236

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures

Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling

Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces

Thermal Degradation

Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed

Contributing Factors Rapid pressure changes Low-

modulus hardness elastomer

Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)

Explosive Decompression

Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable

only by measurement of physical properties

Contributing Factors Incompatibility with the chemicalandor thermal environment

Suggested Solutions Selection of more chemicallyresistant elastomer

Chemical Degradation

8142019 O Ring Brochure

Description The seal or parts of the seal exhibit a flatsurface parallel to the direction or motion Loose particlesand scrapes may be found on the seal surface

Contributing Factors Rough sealing surfaces Excessivetemperature Process environment containing abrasiveparticles Dynamic motion Poor elastomer surface finish

Suggested Solutions Use recommended gland surfacefinishes Consider internally lubed elastomers Eliminateabrasive components

Abrasion

Description The seal often exhibits discolouration as wellas powdered residue on the surface and possible erosion ofelastomer in the exposed area

Contributing Factors Chemical reactivity of the plasmaIon bombardment (sputtering) Electron bombardment(heating) Improper gland design Incompatible sealmaterial

Suggested Solutions Plasma-compatible elastomer andcompound Minimize exposed area Examine gland design

Plasma Degradation

Description The seal exhibits foreign materials on thesurface andor within the O-ring

Contributing Factors Process environment depositionReactions or degradation of the elastomer Non-semiconductor-grade elastomer

Suggested Solutions Specify contamination levelincluding manufacturing and packaging of the seals

Machining Specifcations

O-Ring Gland Types

O-rings are primarily used to prevent the loss of a fluid or gas However O-rings can be used asdust seals drive belts or on rotating shafts Most O-ring seals can be classified into one of the threearrangements shown below

Whereas the ID or OD of the O-ring for a design is significantly influenced by the diameter of themating components (pistonrod and bore) the cross-section of the O-ring is usually fairly arbitraryThe following table describes some of the advantages when opting for a small cross-section or alarge cross-section

Selecting an O-Ring Cross-Section

Piston Configuration Rod Configuration

Face Type Configuration

bull More compactbull Lighter weightbull Less expensive especially for higher cost

elastomers like FKM or fluorosiliconebull Less machining required for machined grooves

since grooves are smallerbull More resistant to explosive decompression

bull Less prone to compression setbull Less volume swell in liquid on a percentage

basisbull Allows for larger tolerance while still

maintaining acceptable compression squeezeand compression ratio over full stack-up range

bull Less prone to leakage due to contaminationdirt lint scratches etc

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are

ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)

Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

There are different methods to counter O-ring

extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference

For hydraulic and pneumatic piston sealing applications

The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range

and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance

For hydraulic and pneumatic rod sealing applications

The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside

diameter interference

For hydraulic and pneumatic static axial sealing applications

An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following

housing dimensions apply

Reduction in Cross-Section

Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch

Compression

The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

HCS

Compression Squeeze

Compression Squeeze = CS - H

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Machining Specifcations

O-Ring Gland Types

O-rings are primarily used to prevent the loss of a fluid or gas However O-rings can be used asdust seals drive belts or on rotating shafts Most O-ring seals can be classified into one of the threearrangements shown below

Whereas the ID or OD of the O-ring for a design is significantly influenced by the diameter of themating components (pistonrod and bore) the cross-section of the O-ring is usually fairly arbitraryThe following table describes some of the advantages when opting for a small cross-section or alarge cross-section

Selecting an O-Ring Cross-Section

Piston Configuration Rod Configuration

Face Type Configuration

bull More compactbull Lighter weightbull Less expensive especially for higher cost

elastomers like FKM or fluorosiliconebull Less machining required for machined grooves

since grooves are smallerbull More resistant to explosive decompression

bull Less prone to compression setbull Less volume swell in liquid on a percentage

basisbull Allows for larger tolerance while still

maintaining acceptable compression squeezeand compression ratio over full stack-up range

bull Less prone to leakage due to contaminationdirt lint scratches etc

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are

ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)

Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

There are different methods to counter O-ring

extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference

For hydraulic and pneumatic piston sealing applications

The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range

and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance

For hydraulic and pneumatic rod sealing applications

The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside

diameter interference

For hydraulic and pneumatic static axial sealing applications

An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following

housing dimensions apply

Reduction in Cross-Section

Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch

Compression

The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Machining Specifcations

O-Ring Gland Types

O-rings are primarily used to prevent the loss of a fluid or gas However O-rings can be used asdust seals drive belts or on rotating shafts Most O-ring seals can be classified into one of the threearrangements shown below

Whereas the ID or OD of the O-ring for a design is significantly influenced by the diameter of themating components (pistonrod and bore) the cross-section of the O-ring is usually fairly arbitraryThe following table describes some of the advantages when opting for a small cross-section or alarge cross-section

Selecting an O-Ring Cross-Section

Piston Configuration Rod Configuration

Face Type Configuration

bull More compactbull Lighter weightbull Less expensive especially for higher cost

elastomers like FKM or fluorosiliconebull Less machining required for machined grooves

since grooves are smallerbull More resistant to explosive decompression

bull Less prone to compression setbull Less volume swell in liquid on a percentage

basisbull Allows for larger tolerance while still

maintaining acceptable compression squeezeand compression ratio over full stack-up range

bull Less prone to leakage due to contaminationdirt lint scratches etc

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are

ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)

Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

There are different methods to counter O-ring

extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference

For hydraulic and pneumatic piston sealing applications

The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range

and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance

For hydraulic and pneumatic rod sealing applications

The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside

diameter interference

For hydraulic and pneumatic static axial sealing applications

An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following

housing dimensions apply

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are

ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)

Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

There are different methods to counter O-ring

extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference

For hydraulic and pneumatic piston sealing applications

The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range

and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance

For hydraulic and pneumatic rod sealing applications

The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside

diameter interference

For hydraulic and pneumatic static axial sealing applications

An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following

housing dimensions apply

Reduction in Cross-Section

Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch

Compression

The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces

Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression

Suggested solutions Gland design should take into

account material responses to chemical and thermalenvironments

Over-Compression

Description The seal exhibits cuts or marks which spiralaround its circumference

Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness

elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication

Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings

Spiral Failure

Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered

Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing

Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings

Extrusion (andor Nibbling)

Common O-Ring Failures

8142019 O Ring Brochure

Description The seal exhibits a flat-sided cross-section theflat side corresponding to the mating seal surfaces

Contributing Factors Excessive compression Excessivetemperature Incompletely cured elastomer Elastomer withhigh compression set Excessive volume swell in chemical

Suggested Solutions Low compression set elastomerProper gland design for the specific elastomer Confirmmaterial compatibility

Compression Set

Description The seal or parts of the seal may exhibit smallcuts nicks or gashes

Contributing Factors Sharp edges on the glands orcomponents Improper sizing of elastomer Low-modulus

hardness elastomer Elastomer surface contamination

Suggested Solutions Remove all sharp edges Propergland design Proper elastomer sizing Higher-modulushardness elastomer

Installation Damage

Description The failure is often very difficult to detect fromexamination of the seal The seal may exhibit a decrease incross-sectional size

Contributing Factors Improper or improperly curedelastomer High vacuum levels Low hardnessplasticizedelastomer

Suggested Solutions Avoid plasticized elastomers Ensure

all seals are properly post-cured to minimize outgassing

OutgassingExtraction

8142019 O Ring Brochure

httpslidepdfcomreaderfullo-ring-brochure 3236

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures

Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling

Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces

Thermal Degradation

Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed

Contributing Factors Rapid pressure changes Low-

modulus hardness elastomer

Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)

Explosive Decompression

Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable

only by measurement of physical properties

Contributing Factors Incompatibility with the chemicalandor thermal environment

Suggested Solutions Selection of more chemicallyresistant elastomer

Chemical Degradation

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are

ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)

Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

Rod Type sealExtrusion Gap = Bore 983088- Rod 983088

There are different methods to counter O-ring

extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference

For hydraulic and pneumatic piston sealing applications

The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range

and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance

For hydraulic and pneumatic rod sealing applications

The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside

diameter interference

For hydraulic and pneumatic static axial sealing applications

An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following

housing dimensions apply

Reduction in Cross-Section

Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch

Compression

The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

HCS

Compression Squeeze

Compression Squeeze = CS - H

This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures

Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling

Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces

Thermal Degradation

Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed

Contributing Factors Rapid pressure changes Low-

modulus hardness elastomer

Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)

Explosive Decompression

Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable

only by measurement of physical properties

Extrusion GapExtrusion is a concern for radial seals where there is gap between the piston and the bore for a pistontype seal or between the rod and the bore for a rod type seal It is not typically a concern for facetype seals where the metal parts to be sealed are in contact line-to-line The issue is that at higherpressures and especially for softer O-ring elastomers the O-ring can be forced by the pressure intothe small gap between the piston (or rod) and the bore Unless the bore and the piston (or rod) are

ensured to remain concentric by the hardware we have to assume that entire possible gap can shiftto one side (see diagram below)

Piston Type SealExtrusion Gap= Bore 983088- Piston 983088

Rod Type sealExtrusion Gap = Bore 983088- Rod 983088

There are different methods to counter O-ring

extrusion One of these methods is to simplyincrease the durometer rating of the O-ringHowever as you increase the durometer theO-ring can become less malleable Anotheroption would be the use of anti-extrusiondevices These are thin rings made of hardplastic materials such as PTFE Nylon and PEEKOnce in place these ring will provide essentiallyzero clearance

ID StretchOD Interference

For hydraulic and pneumatic piston sealing applications

The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range

and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance

For hydraulic and pneumatic rod sealing applications

The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside

diameter interference

For hydraulic and pneumatic static axial sealing applications

An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following

housing dimensions apply

Reduction in Cross-Section

Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch

Compression

The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

HCS

Compression Squeeze

Compression Squeeze = CS - H

This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

ID StretchOD Interference

For hydraulic and pneumatic piston sealing applications

The nominal O-ring inside diameter d983089 should be stretched between 2 and 5 for dynamicapplications and 2 and 8 for static applications For O-rings with a diameter d983089 smaller than 20mm this is not always possible which can result in a wider range of stretch To minimize this range

and the maximum stretch it is necessary to minimize the tolerance of the housing diameter d983091and have a less stringent requirement for the minimum O-ring stretch In dynamic applicationsit is important to keep the maximum stretch to 5 or less to avoid detrimental effects on sealingperformance

For hydraulic and pneumatic rod sealing applications

The O-ring outside diameter (d983089 + 2d983090) should be at least equal to or larger than the housing outsidediameter d983092 to give interference on the outside diameter The O-ring outside diameter should notexceed 3 of the housing outside diameter for O-rings with a diameter d983089 greater than 250 mmor 5 for O-rings with a diameter d983089 smaller than 250 mm For O-rings with a diameter d983089 smallerthan 20 mm this is not always possible due to tolerance issues which can result in a greater outside

diameter interference

For hydraulic and pneumatic static axial sealing applications

An O-ring is compressed in the axial direction An O-ring can be pressurized from an internal orexternal source A proper housing design minimizes the number of gaps through which the O-ringcan extrude and reduces potential damage to the O-ring during assembly In this case the following

housing dimensions apply

Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch

Compression

The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

HCS

Compression Squeeze

Compression Squeeze = CS - H

This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Reduction in Cross-Section

Elastomers seal by their ability to be compressed therefore if the ID of the O-ring is stretched thecross-section of the O-ring will decrease The following table gives the O-ring cross-sections thatresult of from various percentages of ID stretch

Compression

The difference between the original O-ring cross-section and the final O-ring cross-section onceinstalled is known as the compression squeeze

HCS

Compression Squeeze

Compression Squeeze = CS - H

This can usually be expressed as a percentage O-Ring CS Squeeze () = Compression Squeeze CS

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

h- housing height

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures

Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling

Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces

Thermal Degradation

Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed

Contributing Factors Rapid pressure changes Low-

modulus hardness elastomer

Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)

Explosive Decompression

Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable

only by measurement of physical properties

Contributing Factors Incompatibility with the chemicalandor thermal environment

Suggested Solutions Selection of more chemicallyresistant elastomer

The gland fill is the percentage of the gland that is occupied by the O-ring It is calculated by dividingthe cross-sectional area (CSA) of the O-ring by the cross-sectional area of the gland

Area of a circle = πr1048626 and r = D 2 where D = diameter (CS)Therefore O-ring CSA = π CS 1048626 2( )

Gland CSA = h x w

It is important to consider the housing fill or occupancy of the installed O-ring to avoid detrimentaleffects on radial sealing performance Housing fill of the installed O-ring should not be more than85 to allow for possible O-ring thermal expansion volume swell due to fluid exposure and effectsof tolerances

Volume change is the increase or decrease of the volume of an elastomer after it has been incontact with a fluid measured in percent () For static O-ring applications volume swell up to30 can usually be tolerated For dynamic applications 10 or 15 swell is a reasonable maximumunless special provisions are made in the gland design itself This is a general rule and there mayoccasionally be exceptions

It is also important to note there are significant differences in the coefficients of thermal expansionand contraction between the O-ring material and the housing materials Elastomers can havecoefficients of expansion 7 to 20 times higher than that of metal such as steel

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures

Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling

Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces

Thermal Degradation

Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed

Contributing Factors Rapid pressure changes Low-

modulus hardness elastomer

Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)

Explosive Decompression

Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable

only by measurement of physical properties

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures

Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling

Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces

Thermal Degradation

Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed

Contributing Factors Rapid pressure changes Low-

modulus hardness elastomer

Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)

Explosive Decompression

Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable

only by measurement of physical properties

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces

Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression

Suggested solutions Gland design should take into

account material responses to chemical and thermalenvironments

Over-Compression

Description The seal exhibits cuts or marks which spiralaround its circumference

Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness

elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication

Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings

Spiral Failure

Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered

Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing

Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings

Extrusion (andor Nibbling)

Common O-Ring Failures

8142019 O Ring Brochure

Description The seal exhibits a flat-sided cross-section theflat side corresponding to the mating seal surfaces

Contributing Factors Excessive compression Excessivetemperature Incompletely cured elastomer Elastomer withhigh compression set Excessive volume swell in chemical

Suggested Solutions Low compression set elastomerProper gland design for the specific elastomer Confirmmaterial compatibility

Compression Set

Description The seal or parts of the seal may exhibit smallcuts nicks or gashes

Contributing Factors Sharp edges on the glands orcomponents Improper sizing of elastomer Low-modulus

hardness elastomer Elastomer surface contamination

Suggested Solutions Remove all sharp edges Propergland design Proper elastomer sizing Higher-modulushardness elastomer

Installation Damage

Description The failure is often very difficult to detect fromexamination of the seal The seal may exhibit a decrease incross-sectional size

Contributing Factors Improper or improperly curedelastomer High vacuum levels Low hardnessplasticizedelastomer

Suggested Solutions Avoid plasticized elastomers Ensure

all seals are properly post-cured to minimize outgassing

OutgassingExtraction

8142019 O Ring Brochure

httpslidepdfcomreaderfullo-ring-brochure 3236

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures

Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling

Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces

Thermal Degradation

Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed

Contributing Factors Rapid pressure changes Low-

modulus hardness elastomer

Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)

Explosive Decompression

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces

Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression

Suggested solutions Gland design should take into

account material responses to chemical and thermalenvironments

Over-Compression

Description The seal exhibits cuts or marks which spiralaround its circumference

Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness

elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication

Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings

Spiral Failure

Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered

Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing

Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces

Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression

Suggested solutions Gland design should take into

account material responses to chemical and thermalenvironments

Over-Compression

Description The seal exhibits cuts or marks which spiralaround its circumference

Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness

elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication

Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings

Spiral Failure

Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered

Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing

Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures

Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling

Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces

Thermal Degradation

Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed

Contributing Factors Rapid pressure changes Low-

modulus hardness elastomer

Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)

Explosive Decompression

Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable

only by measurement of physical properties

Contributing Factors Incompatibility with the chemicalandor thermal environment

Suggested Solutions Selection of more chemicallyresistant elastomer

Chemical Degradation

Description The seal exhibits parallel flat surfaces(corresponding to the contact areas) and may developcircumferential splits within the flattened surfaces

Contributing Factors Improper design-failure to accountfor thermal or chemical volume changes or excessivecompression

Suggested solutions Gland design should take into

account material responses to chemical and thermalenvironments

Over-Compression

Description The seal exhibits cuts or marks which spiralaround its circumference

Contributing Factors Difficult or tight installation(static) Slow reciprocating speed Low-modulushardness

elastomer Irregular O-ring surface finish (includingexcessive parting line) Excessive gland width Irregular orrough gland surface finish Inadequate lubrication

Suggested Solutions Correct installation proceduresHigher-modulus elastomers Internally-lubed elastomersProper gland design Gland surface finish of 8-16 microinchRMS Possible use of polymer backup rings

Spiral Failure

Description The seal develops ragged edges (generallyon the low-pressure side) which appear tattered

Contributing Factors Excessive clearances Excessivepressure Low-modulushardness elastomer Excessivegland fill Irregular clearance gaps Sharp gland edgesImproper sizing

Suggested Solutions Decrease clearances Higher-modulushardness elastomer Proper gland design Use ofpolymer backup rings

Description The seal exhibits a flat-sided cross-section theflat side corresponding to the mating seal surfaces

Contributing Factors Excessive compression Excessivetemperature Incompletely cured elastomer Elastomer withhigh compression set Excessive volume swell in chemical

Suggested Solutions Low compression set elastomerProper gland design for the specific elastomer Confirmmaterial compatibility

Compression Set

Description The seal or parts of the seal may exhibit smallcuts nicks or gashes

Contributing Factors Sharp edges on the glands orcomponents Improper sizing of elastomer Low-modulus

hardness elastomer Elastomer surface contamination

Suggested Solutions Remove all sharp edges Propergland design Proper elastomer sizing Higher-modulushardness elastomer

Installation Damage

Description The failure is often very difficult to detect fromexamination of the seal The seal may exhibit a decrease incross-sectional size

Contributing Factors Improper or improperly curedelastomer High vacuum levels Low hardnessplasticizedelastomer

Suggested Solutions Avoid plasticized elastomers Ensure

all seals are properly post-cured to minimize outgassing

OutgassingExtraction

httpslidepdfcomreaderfullo-ring-brochure 3236

Description The seal may exhibit radial cracks locatedon the highest temperature surfaces In addition certainelastomers may exhibit signs of softening-a shiny surface asa result of excessive temperatures

Contributing Factors Elastomer thermal propertiesExcessive temperature excursions or cycling

Suggested Solutions Selection of an elastomer withimproved thermal stability Evaluation of the possibility ofcooling sealing surfaces

Thermal Degradation

Description The seal exhibits blisters pits or pocks onits surface Absorption of gas at high pressure and thesubsequent rapid decrease in pressure The absorbed gasblisters and ruptures the elastomer surface as the pressureis rapidly removed

Contributing Factors Rapid pressure changes Low-

modulus hardness elastomer

Suggested Solutions Higher-modulushardnesselastomer Slower decompression (release of pressure)

Explosive Decompression

Description The seal may exhibit many signs ofdegradation including blisters cracking voids ordiscoloration In some cases the degradation is observable

only by measurement of physical properties

Contributing Factors Incompatibility with the chemicalandor thermal environment

Suggested Solutions Selection of more chemicallyresistant elastomer

Chemical Degradation

Description The seal or parts of the seal exhibit a flatsurface parallel to the direction or motion Loose particlesand scrapes may be found on the seal surface

Contributing Factors Rough sealing surfaces Excessivetemperature Process environment containing abrasiveparticles Dynamic motion Poor elastomer surface finish

Suggested Solutions Use recommended gland surfacefinishes Consider internally lubed elastomers Eliminateabrasive components

Abrasion

Description The seal often exhibits discolouration as wellas powdered residue on the surface and possible erosion ofelastomer in the exposed area

Contributing Factors Chemical reactivity of the plasmaIon bombardment (sputtering) Electron bombardment(heating) Improper gland design Incompatible sealmaterial

Suggested Solutions Plasma-compatible elastomer andcompound Minimize exposed area Examine gland design

Plasma Degradation

Description The seal exhibits foreign materials on thesurface andor within the O-ring

Contributing Factors Process environment depositionReactions or degradation of the elastomer Non-semiconductor-grade elastomer

Suggested Solutions Specify contamination levelincluding manufacturing and packaging of the seals
