High Performance Polyurethane U-Cup Seal 

The most common U-Cup seal in use today. It's ability to used in almost every application makes the HU style the industry work horse. The unloaded urethane U-cup design provides an excellent heavy-duty seal for both piston or rod applications and works well in static and dynamic applications. 

The sealing lips are accurately machined trimmed to ensure good low pressure sealing while the material resists extrusion at high pressures.

Features

  • Symmetrical, single acting piston/rod seal, no interference on the ID or OD.
  • Excellent static and dynamic sealing performance.
  • Excellent performance in low pressure conditions.
  • Useable for long stroke lengths.
  • Negligible tendency to “stick-slip” effect above a speed of 0.15 m/s.
