U-seals, Polypaks, U-cups

US-90URE-6-1/4×7×3/8

Style 850 u-seals offer excellent resistance to extrusion and abrasion. The round cross-section expander offers energized sealing from zero to 5,000 psi.

95A Durometer | Urethane Material | 4 1/2 in Nominal Inner Diameter | 7/32 in Cross Section | 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 | 38 MM Nominal Inner Diameter | Rod U-Seal

Features

• Excellent low temperature performance
• Easy installation

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 | 1 1/4 in Nominal Inner Diameter | 1/8 in Cross Section | U-Seal

The HMU style multi-lip rod u-seal combines the pressure-compensating, uni-directional characteristics of a u-seal, with the multi-lip sealing effectiveness of compression-type stacked-packings. Made from premium materials, the, HMU utilizes several sealing lip edges for dry rod performance while minimizing friction. The multi-lip design maintains, a critical sealing edge even though increasing pressure moves the line of contact down toward the heel.

92A Durometer | Urethane Material | 1 3/4 in Nominal Inner Diameter | 3/16 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 | 3 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

US-90URE-3/4×1×1/4

US-90URE-2-1/8×2-1/2×5/16

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.

92A Durometer | Urethane Material | 1 3/4 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

Features

• General purpose rod seal
• Robust design
• Excellent wear resistance
• Increase seal stability
• Performs well over wide temperature range and is extremely effective in low temperatures
• Primary lip protection
• Easy to install

Style HSU u-seals are precision molded from 80A Durometer Buna-N rubber or 90A Fluorocarbon (suffix “V”) — 80A Duro Rubber for abrasion resistance and 90A Duro Fluorocarbon for heat resistance. These seals are commonly found in industrial cylinders as piston, rod and cushion seals.
