The SharkBite 1/2-in PEX barb x 3/8-in (1/2-in OD) compression angle multi-turn 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-in barb end can be connected to PEX pipe using copper crimp rings or stainless steel clamps.
