1 Industrial Seal Inc. offers a wide range of hydraulic and pneumatic Piston seal profiles to meet the broad demands of the fluid power industry. These Piston seals are offered in a variety of compounds and lip geometries for the best possible solution for a given application. PI DISOGRIN Asymmetrical Piston U-Cup Piston series U-cup with asymmetric profile of the sealing lips, chamfered sealing edges. Knife cut static and dynamic lips for maximum sealing force and fit. DISOGRIN 9250 Material with outstanding wear and tear resistance, ensuring maximum service life. Temperature (Typ.)-54 C/149 C / -65 F to 300 F Pressure 6000 Psi / 40 MPa Speed 1.5 ft/s / 0.5 m/s bulldozers forklifts mobile arm trucks presses standard hydraulic cylinders The PI Piston Seal provides superb sealing performance and very long service life. The single acting design can be used separately for single acting cylinders, or in back-to-back tandems for double acting cylinders. The asymmetrical design assures the highest performance by preventing tipping and twisting in the housing, thus assuring low leakage performance. The knife-cut lips on both the dynamic and static sides assures maximum sealing force to provide maximum motion control while preventing drift. no adhesion effect on sliding surface, even after a long standstill superior performance over a wide range of temperatures and hydraulic fluids

2 DISOGRIN POLY-HONE Square Seal 1704 Series POLY-HONE are directly interchangeable with SQUARE cross section PTFE or urethane seals. POLY-TEMP II Material is a polyester elastomer with fiber glass reenforcement. Easy to install and low cost Pressure (Typ.)5000 Psi / 35 Mpa Temperature (Typ.)-54 C/135 C to -65 F/275 F bulldozers forklifts construction equipment mobile arm trucks mobilelifts general cylinders Poly-Hone Piston Seals are directly interchangeable with TFE, urethane, and rubber seals now being used. The 1704 is a square cross section that has a small footprint, making it resistant to hydroplaning, and is very effective at low pressures. 'O' leakage at low and high PSI easy to install, no resizing superior physical properties operating temperatures of -65 F to +275 F

3 DISOGRIN POLY-HONE Heavy Duty Rectangular Seal 1710 Series POLY-HONE Heavy Duty work in honed or super smooth tubing. The 1710 series with rectangular cross section is designed to withstand 5000 PSI working pressure and hardware clearance as much as.015". Easy to install, will not retro fit any other grooves Pressure (Typ.)5000 Psi / 35 Mpa Speed 4.2 ft/s / 1.4 m/s Temperature -54 C to 135 C/ -65 F to 275 F bulldozers construction equipment forklifts tailgate lifts mobile arm trucks standard hydraulic cylinders Poly-Hone Piston Seals are directly interchangeable with TFE, urethane, and rubber seals now being used. The 1710 is as rectangular cross section that has a much larger footprint. It is designed for the more demanding application and is able to withstand much higher shock loads. Its rectangular shape resists rolling or twisting, making it more stable in the groove. Optimum pressure distribution high static seal-ability excellent scraping action easy to install operating temperatures of -65 F to +275 F

4 DISOGRIN Rectangular Piston M-SEAL 1716 M-SEAL Series is direct replacement and upgrade for either O-ring and Two back-ups or U-cup seal Series' larger width gives resistance to spiral failure. Result is quiet operating seal with less running friction and easy installation. Series 1716 interchange with Grover Series 12 seals Temperature-54 C/149 C to -65 F/300 F Pressure 5800 Psi / 40 Mpa earth moving equipment forklift trucks HGV loading cranes loading platforms standard hydraulic cylinders M-Seals are designed to be a bi-directional low and high pressure seal. Because of the unique unit loading, they are a very positive, no drift seal. This type of seal design will not withstand a great amount of side loading. To increase the life of the seal, Verco 'Cool Blue' Wear Rings should be used in conjunction with the M-Seal. This will ensure centering and compensate for any side loading or misalignment. fluid reservoir provides extra lubrication for reduced breakaway and running friction provides improved stability to resist cocking, twisting, sticking, and rolling easy installation vented, which makes the seal to be more responsive to high speed pressure shifts

5 DISOGRIN M-SEAL with Pronounced Sealing Edge 1718 M-SEAL Series is designed to replace an O-ring without back-up rings. Rectangular cross section design is very resistant to rolling or twisting. Replacing an O-ring and 2 back-ups, using appropriate Seal and 2, 1756 Series back-up rings is recommended Temperature-54 C/104 C to -65 F/220 F Pressure 5800 Psi / 40 Mpa earth moving equipment forklift trucks HGV loading cranes loading platforms standard hydraulic cylinders M-Seals are designed to be a bi-directional low and high pressure seal. Because of the unique unit loading, they are a very positive, no drift seal. This type of seal design will not withstand a great amount of side loading. To increase the life of the seal, Verco 'Cool Blue' Wear Rings should be used in conjunction with the M-Seal.

6 DISOGRIN Compact Double Acting Piston Seal DISO PAC series sealing edges provide effective static and dynamic sealing while groove forms a lubrication reservoir to reduce friction. Grooves on both sides prevent blow by during sudden pressure changes. Premium NBR Square energizer prevents twisting. DISOGRIN premium 928 urethane provides excellent extrusion and wear resistance.

7 DISOGRIN Double Acting Piston Seal with Anti Extrusion Rings VCT series is a double acting, high pressure, high performance, piston seal. With VERCO Ultra-Precision wear rings, it will accommodate very large extrusion gaps. Cap is loaded both in static mode through high energizer squeeze and dynamic mode through proportional axial to radial conversion of system pressure levels.three groove styles to choose from. VCT The Capped T-Seal is a double-acting, high-pressure, high performance piston seal accommodating larger extrusion gaps when used in conjunction with the Ultra-Precision Wear Rings. All members of the assembly (backup and seal ring) are energized by the load ring. Thus, there is no leak path for contamination to work on the primary seal and shorten it's life. will work in virtually any highly contaminated system far better than other seals of this type consists of a filled PTFE cap, and an elastomeric energizer that are protected from extrusion and contamination by Verlon back-up rings designed to handle temperature extremes, a wide variety of fluid media and

8 DISOGRIN Cup Packing, Single Acting, Light Duty CUP packings are single-acting non-symmetrical "liptype piston seals" for reciprocating motion applications. Installed in pairs, they can be used in double acting cylinders. CUP packings are designed to retrofit the well known old leather packings. Suitable for low-pressure piston sealing applications. Due to their flexibility and 9250 material strength,close tolerances and fine rod finishes are not required. CUP Please contact Industrial Seal Inc.
