JG ProLock Pipe Joining System
Twist-to-Lock Pipe-Joining System w/ Secondary Locking Feature for Added Security
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. ProLock fittings carry a 25 year warranty against manufacturing or material defects and have been approved for use in hot and cold water plumbing and hydronic heating applications.
