SharkBite Max slip ball valves are ideal for replacing or adding a new ball valve into an existing line to shut-off water flow for servicing and making repairs. Slip feature allows for two in of rigid copper or CPVC pipe to be cut out of an existing line and connected back together by using the disconnect tool to slide the fitting back to the other end of pipe. Innovative push-to-connect design makes for quick and easy installation. Good item to keep on hand for freezes or other emergency repairs.
