ABSTRACT:
An improved valve for water faucets or the like. The valve has a stem with a locking surface at the lower end thereof, and a seal that has a coacting locking surface matingly engaging the stem locking surface. The locking surfaces are so formed that separation of the seal from the stem is prevented when assembled in the valve but the seal comes apart when removed from the valve. The seal means has a pair of blocking surfaces and a pair of undercut portions with only one of each pair being in operative relationship to a single water exit so that when the operative blocking surface becomes worn, the stem-seal assembly may be turned 180.degree. for restoring the valve to its normal operating condition.
