Abstract: A faucet valve is operated by a rotatable stem which is inserted in a tube-shaped housing. The valve, preferably composed of brass, is screwed into a standard size plumbing fixture. The body of the stem is disposed between a washer preferably made of teflon and an "O" ring, which exerts a pressure between said body of the stem and the tube. The pressure does not generally vary according to the fluid pressure therein or fluid flow therethrough enabling the valve to be used in high pressure applications. A stationary valving member within the housing mates with a cooperating rotatable valving member which is driven by the stem. The operating end of the stem is thick relative to the housing into which it fits; this thickness allows the operating part of the stem to be able to handle relatively large operating force without bending or breaking. A pin and cooperating slot provide a 90.degree. limit on stem rotation.
