Item Information

The WT composite sealing washer is designed for direct sealing on the thread. The lips seal the leakage path of the threads. The composite sealing washer consists of a metal washer and an elastomer sealing lip with a rectangular cross section and an additional mechanical connection to the inside edge of the supporting washer. The serrations achieve a positive connection of the elastomer with the supporting washer and prevent the phenomenon of sheared sealing lips which is frequently encountered with composite sealing washers.
WT composite sealing washers ensure reliable sealing of screws in the threaded area (only static, no dynamic threads). Assembly is self-centering and directionally independent.

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