Item Information

The WO composite sealing washer is designed for radial sealing below the screw head in the area of the smooth (non-threaded) screw shaft. This provides three functionally relevant sealing areas. WO consists of a metal washer and an elastomer sealing lip with a circular cross section and 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.

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