摘要
A valve housing assembly includes a valve body member that has an exterior threaded section which can engage an interior threaded section of a cap member. The cap member and valve body member have opposing shoulders. An abutment ring made from a semi-rigid material of talc filled propylene is interposed between the two opposing shoulders and provides for seal between the two opposing shoulders to the threaded section. Furthermore, the semi-rigid abutment ring will undergo slight compression when the cap member is fully tightened onto the body member and will creep back over a period of time to alleviate vertical forces which can cause seizing of the threaded sections of the cap member and body member which would otherwise prevent easy removal of the cap member from the body member. Furthermore, the sealing of the ring between the two shoulders reduces the chance of corrosion by eliminating water leaking into the threaded section from the interior of the valve body. The seal further reduces forces that seize the cap onto the body member and provides for a cap member which is easily removable from the body member long after it has been tightened onto the body member.
