The Shark Bite PVC Transition Slip Tee allows you to add a line into your existing plumbing system while converting from Copper (CTS) pipe to PVC pipe. The slip feature allows you to cut into an existing Copper or CPVC pipe and run out PVC Schedule 40, 80 or 120 from the Tee. The white collar center connection fits Schedule 40, 80, 120 PVC and also can be used on IPS CPVC Schedule 40 and 80 pipes. Simply insert the slip coupling onto the pipe and using the PVC depth gauge and disconnect clip to slip the fitting back onto the other end of pipe completing the connection.
