High Performance Seals for Extreme

Aerospace Environments

Sealing Solutions for Aerospace

The equipment that moves today’s industry is more reliable

and highly engineered than ever before. That’s why Parker

develops and manufactures engineered sealing solutions –

technologically advanced sealing devices and materials

that can keep pace with aggressive chemicals, high

temperatures and high and low pressures.

Our sealing products have our unique combination of

experience and innovation built right in, and we’re able to

supply them quickly and cost effectively to fit virtually any

application you can think of.

Diamond Seals

• Parker Diamond Seals,

designed for face sealing

applications, provide robust

sealing with retention while

requiring a fraction of the

space and load of traditional

seals.

Tadpole Tapes

• High temperature, flame-

resistant tadpole tapes from

Parker are used in firewall

closures and structural

sealing. Resilient, non-

hardening materials can be

customized for temperature

exposure and bolting force to

suit requirements.

FlexiSeals – Spring Energized PTFE

Seals (Air Management Systems)

• FlexiSeals® from Parker

Praedifa used in cabin air

conditioning systems

withstand temperatures up to

+260° C (500° F), are resistant

to dynamic movements and

meet the long lifetime

expectations of the industry.

Custom Rotary Shaft Seals for

Aerospace

• Parker's wide range of rotary shaft

seal options provide superior

elastomer lip material options for

improved wear resistance and

enhanced performance. Custom

and standard solutions are

available in a wide range of

elastomeric, PTFE or labyrinth

designs for engine, air

management, landing gear &

wheel and brake applications.

Custom Expansion Joints

• Custom expansion joints from

Parker manage movement,

vibration and misalignment

between ducting and mating

surfaces in aerospace air

management systems.

VX065

• O-rings made from VX065

deliver the extreme low

temperature performance

needed at high altitudes and

during engine startup. With

outstanding compression set

resistance, VX065 significantly

extends seal life in low

temperature fuel applications

where traditionally only

fluorosilicone could be used.

FF200

• Parker's ULTRA FF200

exceeds AMS 7257C,

demonstrating superior

retention of mechanical

properties and resistance to

compression set after longer

term fluid exposure and high

temperature.

Metal Seals (Jet Engines)

• Metal seals used in jet engines

withstand temperatures up to

1100° C (+2000° F) and

pressures up to 6200 bar while

ensuring extremely low

leakage rates.

Sealing Systems for Hydraulic

Actuators (Landing Gear)

• Parker Praedifa provides a

wide range of sealing systems

for hydraulic actuators

providing excellent

compatibility with common

aerospace fluids and

withstanding temperatures

down to -50° C (-58° F).

VMQ, PVMQ Extruded Profiles

• Parker's expertise in custom

extruded and spliced seals

enables highly complicated

geometries and shapes such

as 3-D, multi-corner and

compression-limited gaskets,

while providing superior high

bond integrity. This

customized solution does not

require tooling, and the seals

are devoid of parting lines,

flow lines, flash and void.

Fabric Reinforced Products

• Increase material strength with

low closure force sealing to

create a variety of products

including bellows, profile seals

and aerodynamic seals.
