High Performance Polyurethane Piston U-Cup Seal
The PU Piston U-Cup is an asymmetric piston seal designed to offer effective bore sealing in a wide variety of applications. The outer dynamic lip is shorter and more robust to provide improved sealing and compression set characteristics over conventional U rings. The seal can be used by itself as a single acting seal or fitted back to back in separate grooves for double acting applications.
