Product Introduction
Description
U cup piston seals has a U-shaped/Y-shaped cross-section and it is typical lip seals that installed in a groove with a tight fit. Hydraulic cup seals is designed to provide a dry sealing solution in light and medium-duty applications. It is for easy installation and excellent low temperature performance.
The seal can be considered for use in heavy-duty applications when used with a suitable full depth back-up ring. The sealing lips are trimmed at an angle to give optimal sealing performance.
Hydraulic cup seals makes it ideally suited for single-acting rod or piston applications. Can also be fitted back-to-back for use in double-acting applications.
