The SharkBite Push-to-Connect PVC (Iron Pipe Size) x CTS (Copper Tube Size) is the easiest way to transition from IPS PVC Pipe into CTS Copper, PEX, CPVC or PE-RT in any combination with no soldering, clamps, unions or glue. Just insert the pipe and the stainless steel teeth bite down and grip tight, while a specially formulated O-ring compresses to create a perfect seal. The white collar side fits on 40, 80, 120 PVC and also can be used on IPS CPVC on 40 and 80 pipes. The Mustard collar side fits CTS Copper, PEX, CPVC or PE-RT pipe. Disassembly is just as fast using the SharkBite disconnect tool so fittings and valves can be easily changed and reused. They can even be rotated after assembly for easier installation in tight spaces.
