ABSTRACT:
An elastomeric sleeve is inserted in the hole in the cock body which has multiple passages for the fluid. A plug, which may be positioned to connect selected passages, is placed within the sleeve in the hole. Either the contacting surfaces between the hole and sleeve or the rubbing surfaces between the sleeve and plug are tapered. A spring, seated on the base of the body or a plug flange, exerts upward pressure on the sleeve to assure tight contact between adjacent surfaces to eliminate fluid leaks.
