The SharkBite 1/2” push-to-connect x 1/4” push-to-connect quarter-turn angle stop valve controls water flow to household plumbing fixtures. The angle stop valve is used where the water pipe enters the room to allow for easy shut-off of water flow to the end fixture allowing for maintenance and repair without having to turn water off to the entire home. The SharkBite 1/2" push-to-connect end allows you to simply push on to copper, CPVC or PEX with no solder, clamps, unions or glue. Just insert the pipe and the stainless steel teeth bite down and grip tight, while a specially formulated O-ring compresses to create a perfect seal. Disassembly is just as fast using the simple disconnect tool so fittings and valves can be easily changed and reused. They can even be rotated after assembly for easier installation in tight spaces. The 1/4” outlet end allows you to use a 1/4" stick of PEX Pipe and a SharkBite 1/4".
