Full Product Description

The WX composite sealing washer consists of a metal washer with a rectangular cross section and an elastomer sealing lip with a trapezoidal cross section that is vulcanized to the inside. It has been designed to replace copper washers in high-pressure systems and is a time-tested and low-cost solution for screw head and flange sealing areas. The elastomer sealing lip is chemically bonded to the metal carrier.
The seal has been designed for use in high-pressure applications and can far exceed the sealing effect of copper washers or similar metal seals. Assembly is directionally independent.

Range of application:
Static sealing of flanges or screw heads.
