ASYMMETRICAL UNLOADED U-CUP

Unlike a Standard U-Cup where both sides of the seal have the same dimensions, the Asymmetrical Unloaded U-Cup is designed to have both a static and a dynamic side.  The static side features a tall lip in order to increase the stability of the seal. On the dynamic side, the prominent feature is a reduced height seal lip with good film breaking capabilities.

The Asymmetrical U-Cup is a single direction piston seal, meaning it can only seal if the pressure is coming from one direction. Since the sealing method is single directional, two loaded U-Cups must be installed for dual direction hydraulic piston applications.

Applications: Medium duty uses such as mobile hydraulic, agricultural and general industrial.

Materials: Urethane or Hytrel®

Max Pressure: 5,000 psi

Temperature range: -50°F to +250°F

Max Velocity: 3.2 ft/sec
