Products listed in this catalogue are used in diverse locations and for numerous types of machinery and equipment,and actual conditions of use also differ extensively. Consequently, when using these products, we recommend that youimplement verification tests under the actual conditions of use.Regarding individual applications, it is necessary to make a selection decision based on individual designs and onsuitability evaluations. For special applications, please consult us. The contents of this catalog are subject to change without prior notice.1. Never use for any purpose other than the prescribed application.2. When processing, use sharp cutting tools.3. Always follow the instructions in this catalog or the instruction manual when installing equipment, etc.4. Do not re-use packings unless this is specifically indicated.5. When replacing, carefully remove all of the old material before installing the new product.6. To maintain performance, store packaged products in a cool and dark place.7. Please refer to MSDS (Manufacturer Safety Data Sheet) concerning health and hygiene cautions.8. When disposing, comply with all regulations in your country. Waste should be properly disposed of at a permitted

disposal site. Do not incinerate the used products, especially those containing fluoropolymer resin as it will generatetoxic gas when burning.

TOMBO No.2205-P

Fig. 1 TOMBO No.2205 Cross-section

For packings with cross-sectionaldimensions of less than 4 mm,stainless steel mesh is notincorporated.

Stainless steel meshGraseal sheets

Features1. Superior sealing performance compared to asbestos products.2. Little differences in performance from cyrogenic to high

temperatures.3. Expanded graphite (Graseal) has chemical resistance

properties second only to PTFE, and can be used with almostany fluid (with the exception of those listed below).

4. Less shrinkage at high temperatures than asbestos packings,with little stress relaxation.

ApplicationThermal power plants, petroleum refineries, shipbuilding, chemicalplants, cryogenic services, high temperature gas plants, etc.Cast steel valves, forged steel valves, stainless steel valves, etc.

FluidsWater type fluids (water, hot water, steam, etc.), oil type fluids(oil, heat transfer oil, etc.), organic solvents, hydrocarbons,gaseous fluids (hydrogen, ammonia, etc.), chemical products,corrosive fluids (other than oxidizing fluids), and cryogenicfluids (LN2, liquid air, LNG, LPG, etc.)

Not applicable

ConstructionTOMBO No.2200 series is a packing made from expandedgraphite (Graseal) cut into strips and shaped into rings in amold. The packing is treated to give it anti-corrosion features,and is an excellent packing for high temperature / highpressure applications.We carry TOMBO No.2200-P and TOMBO No.2200-Lmodels of this packing, each having different types ofimpregnated lubricant.The TOMBO No.2205 series is a TOMBO No.2200 packingwith the addition of a stainless steel mesh incorporated intoits center so that the packing can be removed easily. Like theTOMBO No.2200 series, we carry TOMBO No.2205-P andTOMBO No.2205-L models.45 degree bias cut is standard but non-cutting or 2 cutting arealso available on request.

Features1. When used with a Graseal packing, provides the same seal

performance as our conventional Graseal packing sets(TOMBO No.2205-L with TOMBO No.2930, etc.) whilegreatly lowering friction resistance.

2. Little differences in performance from cryogenic to hightemperatures.

3. Expanded graphite (Graseal) has chemical resistance propertiessecond only to PTFE, and can be used with almost any fluid(with the exception of those listed on page 6).

4. Less weight loss at high temperatures than asbestospackings, with little stress relaxation.

ConstructionTOMBO No.2250 features a core of specially lubricated heatresistant inorganic fibers. The exterior of the core is made ofexpanded graphite (Graseal), strengthened with heat resistantmetal (316L stainless steel) filaments and treated with a speciallubricant, graphite, and anti-corrosion materials. This adapterpacking is well suited to high temperature and high pressure valves.

gs Selection Guidelines for High Temperature Use Non-Asbestos PackingsNumber of Rings and Tightening Stress

Table 1 shows the recommended number of rings(combination method), tightening stress, and compressionratios for high temperature use non-asbestos packings (lowtorque combination Graseal packings and Super Sealpackings)

Because these non-asbestos packings have exceptionalsealing performance, sufficient seal performance may beachieved with a fewer number of rings as compared towhen using asbestos packings.

Table 1 Number of Rings and Tightening Stress for High Temperature Use Non-Asbestos Packings

Alignment of Packing CombinationsAs a rule, our TOMBO No.2200 series, TOMBO No.2205series, TOMBO No.2250 and TOMBO No.2930 productscannot be used alone. The TOMBO No.2200 or TOMBONo.2205 packing should be sandwiched between theTOMBO No.2250 or TOMBO No.2930 (etc.) adapterpackings, as shown in the diagram below.

Metal Sleeve UsageBecause these non-asbestos packings have exceptionalsealing performance, sufficient seal performance may beachieved with a fewer number of rings as compared to whenusing asbestos packings. For existing valves that use a largenumber of packing rings, we recommend the use of a metalsleeve in order to avoid excess friction resistance.Metal sleeve specifications are as follows:Material: SUS304 or SUS403, etc.Shape: double splitDimensions

Note: k values (frictional coefficient lateral pressure coefficient) havebeen experimentally determined, but these values can vary dependingon a large number of factors such as the size of the packing, the numberof rings, magnitude of the tightening force, stem diameter, stemfinishing precision, temperature, internal pressure, etc., meaning thatan absolute k value does not exist.

Packing Recommendations - Rotary Shaft Packings

Note: (1) This selection guide shows typical recommended packings for fluids, temperatures, pressures, shaft speeds and PV values and not showingmaximum condition of each rotary shaft packings. Thus, depending on the other conditions, the products shown here are not necessarilysuitable for use in sone cases.

(2) For maximum service condition of each rotary shaft packings, please refer to the description of each product in this catalogue.(3) Rotary shaft packings are basically operated with small amount of leakage to keep lubricity etc. In case leakage of the internal fluid is not

allowed, lantern ring shall be used and the fluid which leakage is allowed shall be filled at 0.1~0.2MPa (1~2kgf/cm2) higher pressure thaninternal pressure.

TOMBO No.9038 can not be used for strong oxidizingacids such as fuming sulfuric acid, concentrated sulfuricacid, chromic acid, aqua legia etc.This packing is not used for the fluids which contaminationis not allowed, such as drinking water, pharmaceuticals,comestibles, semi-conductor manufacturing etc.

Features1. Graphite particles containing PTFE yarn is excellent in

chemical resistance and can be used with almost anyfluids other than strong oxidizing acids.

2. Excellent in seal performance at high revolution speeds.3. Because it contains graphite particles in PTFE yarn, heat

dispersion characteristics are very good and among PTFEbase packings, it has the highest heat resistance.

ConstructionGraphite particles containing PTFE yarn is treated with PTFEdispersion and special lubricant, and then braided into squarecross section and further treated with PTFE dispersion.

Packings for Plungers, Rods, Rams and PistonsLip Type Packings TOMBO No.2660 / 2661 / 2665

ApplicationRod and piston seals for cylinder, plungers, Hydraulic rams,valve stems.

FluidWater type fluids (water, waste water, sewage, brine etc.),Oil type water, Air.

Type TOMBO No.2660 Neoduck Molded Packing

Cotton duck treated with synthetic rubber is molded intoring forms.

TOMBO No.2661 Rubber Molded PackingVarious kinds of rubber are molded into ring forms. It hasbetter seal performance than TOMBO No.2660 NeoduckMolded Packing but less pressure resistance. Servicerange depends on rubber material.

TOMBO No.2665 Slip Mold PackingSurface of TOMBO No.2660 is treated with PTFE dispersionfor easy conformity to rod or shaft surface for initial break-inperiod.

ConstructionThis type of packing is expanded automatically by fluidpressure and forms tight seal against stuffing box wall orshaft. Thus it is called atuomatic sealing packing.
