3 INCH GLAND ONLY

Used as a companion to our “B” lip configured Style 850 u-seal, Style 855 PRC rings convert a uni-directional u-seal into a bi-directional seal.

Style RU9 seals are molded from MDI based Zurcon® Z25 urethane. This seal offers good elasticity with low, compression set while maintaining a high level of tribological characteristics. The dynamic seal lip incorporates slide, segments that will increase back-pumping capabilities while reducing friction. The RU9 style rod seal is ideal for, hydraulic applications where high temperature and high pressure performance is required.

95A Durometer | Urethane Material | 2 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

Style 870 u-seals are precision molded from Buna-N synthetic rubber. Style 870 u-seal numbers conform in size to Army-Navy specification AN6226.

70A Durometer | Buna-N Rubber Material | 1/8 in Nominal Inner Diameter | U-Seal

Utilizing the same profiles as the Style 800 Polyurethane U-Seal line, these u-seals are molded from a fluorocarbon, compound. While being compatible with a broader range of fluids, these fluorocarbon seals will also operate, continuously at temperatures from -20° to +400 °F. NOTE: If you are not sure of fluid/seal compatibility, please refer, to the fluid compatibility chart in the appendix or contact our Engineering Department.

95A Durometer | Fluorocarbon Material | 1 3/8 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

Utilizing tough polyurethane, these seals possess excellent wear and abrasion resistance. Symmetrical in design, they can be used in rod or piston applications. E= European Urethane.

US-90URE-1-1/4×1-1/2×1/4

Featuring high pressure and high shock load capability, this seal utilizes the same twin lip design found in Hercules®, Sealing Products’ RTU style. With the main body of the seal molded from high performance polyurethane, this seal, incorporates a dynamically designed nitrile energizer and a tough polyacetal anti-extrusion ring. RTUB is capable of, pressures up to 10,000 psi in approved applications. Please consult Hercules Engineering for pressures above 6,000, psi.

The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The unique profile of the NBR energizer ensures the primary sealing lips maintain contact under low or no pressure situations while ensuring proper sealing at higher pressures. The Hallite 621 also incorporates an acetyl anti-extrusion ring to withstand side loads and extreme pressure peaks even with the extrusion gaps.

94A Durometer | Urethane Material | 4 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

4 Gland Kit

Molded in a tough urethane, this rod u-seal fits tightly in the groove while providing increased radial force on the rod.
