ABSTRACT:
A gas valve assembly for a shock absorber includes a first portion of a first material and a second portion of second material which is less rigid than the first material. The first portion defines a rigid valve assembly body having a threaded portion to mount the valve to the shock body. The second portion is resilient and defines an integral plug and annular seal interconnected by a connecting member. The annular seal is molded adjacent a step engagement surface to seal the gas valve assembly to the shock body. A head having a tool engagement surface compresses the annular seal when the gas valve assembly is threaded in place.
