JG ProLock Pipe Joining System

JG ProLock Fittings, from John Guest, is a new Twist-to-Lock pipe-joining system that cuts installation time by 40%. With unprecedented pipe engagement, and a state-of-the-art thermoplastic material, the fittings provide a secondary failsafe locking mechanism that leaves no doubt that the fitting is secured. ProLock fittings are approved for use with Copper, PEX or CPVC and can be used in behind- the-wall installations without the need for access panels*. No tools are required to install or remove ProLock fittings, only a pipe cutter to cut the tubing is needed.
