Mô tả thương mại

Zurcon® U-Cup is a single-acting piston seal available in a wide range of sizes and offered in high-performance polyurethane, Zurcon® Z20. The seal is mainly used in light-duty applications in mobile equipment and is well-suited to installation in closed grooves.

Cài đặt và xử lý

The U-Cup is a single acting piston seal out of injection molded polyurethane. It is provided with a robust dynamic sealing lip and a wide contact area of the static lip, which guarantees 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.
