SharkBite Angle Stops combine push-fit technology with an angle stop quarter turn valve. This allows the valve to control water flow to household plumbing fixtures, and provides easy shut-off of water flow for maintenance and repair, if necessary. These valves require no solder, clamps, unions or glue. The push-to-connect end allows you to push on to Copper, PEX, CPVC or PE-RT pipe easily. This product can be easily rotated after assembly for easy installation, even in tight spaces.
