Engineered for demanding hydraulic applications, this U-seal delivers exceptional sealing performance where standard elastomers fall short. Manufactured from premium 95A Shore A durometer polyurethane, it combines the abrasion resistance of a hard compound with the flexibility needed for reliable dynamic sealing across a wide range of pressures and temperatures.
Key Benefits
Superior abrasion resistance — 95A durometer polyurethane outperforms standard NBR and EPDM seals in high-cycle, high-velocity rod and piston applications
Excellent extrusion resistance — maintains seal integrity under high system pressures without backup rings in many applications
Low compression set — retains sealing force over extended service life, reducing maintenance intervals
Wide chemical compatibility — resistant to petroleum-based hydraulic fluids, mineral oils, and many synthetic fluids
Tight dimensional tolerances — precision-molded for consistent fit in standard hydraulic cylinder grooves
Typical Applications
Hydraulic cylinder rod and piston sealing
Mobile hydraulics and heavy equipment
Industrial presses and actuators
Construction and agricultural machinery
