U-seals, Polypaks, U-cups

Specifically designed as piston seals, these u-seals are engineered to seal on their outside diameter. They offer extended, service life and maximum reliability in piston sealing.

92A Durometer | Urethane Material | 5 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

US-90URE-1-1/4×1-5/8×3/8

Used interchangeably for piston or rod sealing, these u-seals employ the same tough urethane material found in our, Heavy Duty Rod and Piston U-Seals.

92A Durometer | Urethane Material | 5 3/8 in Nominal Inner Diameter | 5/16 in Cross Section | U-Seal

Style DRTU-BHT rod seals are molded in Freudenberg® AU 30000 urethane. These seals are specifically designed, with a second lip on their inside diameter and engineered to attain maximum life and reliability in dynamic rod sealing., This feature results in reduced leakage, less friction, increased stability, and prevents air and contaminants from, entering the cylinder. This high tear-resistant urethane demonstrates stability throughout a wide range of temperatures., In addition, this material is well suited to mineral and biodegradable hydraulic fluids as well as being resistant to, hydrolysis.

These seals are specifically designed to seal on their inside diameter and engineered to attain maximum life and reliability in dynamic rod sealing.

92A Durometer | Urethane Material | 5 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

Style HRU u-seals are precision molded from 80 Durometer Buna-N rubber. Sizes include those found in Army-Navy spec. AN6226 and narrow cross-section sizes found in J.I.C. cylinders and the popularly termed “Huva Cup”.

90A Durometer | Fluorocarbon Material | 1 5/8 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

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

Urethane Material | 25 MM Nominal Inner Diameter | Rod U-Seal

RUS-URE-40.00X50.00X8.00

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

Urethane Material | 50 MM Nominal Inner Diameter | Rod U-Seal

Molded in a tough urethane, this seal employs an additional lip near the heel. The twin lip design provides stability, friction-reducing lube retention, and some contaminant resistance. VME – Secondary lip is further from heel than standard MRTU. NOTE: E = European Urethane.

Urethane Material | 115 MM Nominal Inner Diameter | Rod U-Seal

Features

• Excellent low temperature performance
• Easy installation
