The Flair-it PEXLock 30771 is a 1-inch pipe coupling that joins PEX A, PEX B/C, vinyl hose, and PERT pipe. This fitting works in mixed-material plumbing systems where you need to connect different types of tubing.
Installation requires only a pair of slip-joint pliers—no special calibrated tools needed. The coupling features a reusable, removable clamp that lets you disconnect and reconnect lines without replacing the fitting. The polymer body resists freezing and cracking, and the clamp can be removed and reapplied with no degradation to the PEXLock.
