SharkBite® Large Diameter Ball Valves are the easiest way to install or replace a shut-off valve into your potable water or hydronic water heating system. The push-fit connections allow you to join to Copper, PEX, CPVC, PE-RT and HDPE pipe in any combination without a need for soldering, clamps, glue or unions. The valve is easily rotated after installation making it easier to reach the shut-off, or to work in tight spaces. Large Diameter PEX Stiffeners are required when connecting to PEX tubing.
