The SharkBite faucet installation kit has everything you need to install your new faucet. The kit includes 2 SharkBite 1/2 in. x 1/4 in. (3/8 in. O.D.) push-to-connect straight stop valves, two 5 ft. coils of 1/4 in. PEX pipe, two 1/4 in. (3/8 in. O.D.) SharkBite x 1/2 in. Swivel faucet connectors, and a 1/2 in. Chrome trim cover reversed functions as a disconnect and 1/4 in. disconnect clip to remove the pipe from the fitting if needed. The SharkBite straight stop valves work with copper, PEX or CPVC. 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. Disassembly is just as fast using the simple 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. The included PEX coils can be cut to the exact length needed so there is no excess supply line to coil up under the sink providing a clean, tangle free look. Once the stop valves are installed, thread the 1/2 in. faucet connectors onto the faucet connections and then measure and cut the PEX and push into the outlet on the stop valve and the faucet connector and the installation is complete.
