SEAL MEMBER FOR FAUCET VALVE Abstract of the Disclosure A seal member for a noncompression-type faucet valve comprises a cylindrical member having an open top and an open bottom, both of which are partially closed by inwardly directing flanges. The member is further provided inter- mediate its length with an external outwardly directed circumferential ridge. The seal member is intended for use in a faucet valve which has a rotatable valve stem having an inlet passage offset from the axis of rotation positioned within the bore of a valve housing that has an inlet port which is offset from the axis of the bore. Flow through an outlet tube leading from the bore is controlled by rotating the stem to move the inlet passage into and out of registry with the inlet port in the bore. The seal member is comprised of a resilient material such as butane rubber and it is friction fit into a seal- receiving recess about the inlet port in the bottom of the valve housing. Once the seal member is in place, it is immovable in the recess and a liquid-tight seal is formed between the side wall of the recess and the ridge. Addi- tional liquid-tight seals are formed between the bottom flange and the bottom of the seal-receiving recess and the top flange and the bottom of the valve stem. The latter seals are reinforced by supply line pressure exerted on the inner surface of the flanges.
