The SharkBite push-to-connect 18-in frost-free sill cock is the easiest way to install a new or replace an existing frost-free sill cock. The push-to-connect inlet is compatible with copper, PEX, CPVC or PE-RT pipe. Just insert the pipe and the fittings stainless steel teeth bite down and grip tight, while a specially formulated O-ring compresses to create a perfect seal. Disassembly is just as fast using the simple disconnect tool so fittings and valves can be easily removed and reused. The outlet side is a 3/4-in garden hose connection and the multi-turn handle allows for easy on/off operation.
