Design Meets Technology

JG ProLock, the newest fitting system from John Guest, is the innovation that is changing the way plumbers think about polymer fittings. Using an advanced thermoplastic material for toughness and stability in extreme conditions, ProLock uses a revolutionary Twist-to- Lock design, with an audible click, visible alignment arrows, and unprecedented insertion depth to assure technicians the fitting is secure.

But getting the job done is only part of the beauty of ProLock – it's also about how many jobs ProLock can do, and how easily it can do them. ProLock connects to copper, PEX, and CPVC; is code-approved in Canada and the US; and is approved for behind-wall use. It's non-corrosive, doesn't produce scaling, and requires no adaptations, modifications or tools for installation or removal.

In short, JG ProLock is the do-it- all fitting system that can take your business to new heights. But don't trust us – trust the free sample that John Guest will ship to your door absolutely free.
