The Shark Bite Slip Tee is the perfect way to add a line into your existing plumbing system. The slip feature allows you to cut up to 2 inch of rigid Copper or CPVC pipe and connect them back together using the tee to add the line to your system. Simply insert the slip coupling onto the pipe after youve cut out a section and use the disconnect clip to slide the fitting back to the other end of pipe which completes the connection.
