ZURCON U-CUP PUA

Description

The Zurcon U-Cup PUA is a single acting piston seal out of injection moulded polyurethane. It is provided with a robust dynamic sealing lip and a wide contact area of the static lip, which guaranties an effective positioning in the groove.

The profile is suitable for pressures up to 40 MPa provided that the extrusion gap is adapted to the pressure level. Thanks to the elasticity of the polyurethane material the U Cup can easily be installed in closed grooves.
