John Guest USA introduces JG ProLock Plumbing Fittings, a Twist-to-Lock System

Introducing John Guest ProLock: the first-ever Twist-to-Lock system, from the first name in cutting-edge design and engineering: Versatile – Intuitive – Revolutionary.

JG ProLock moves beyond push-to-connect to twist-and-lock; the audible click and indicator arrows assure installers that the fitting is secure.

The fittings connect to copper, CPVC and PEX, are code-approved, offer a 25-year warranty and are approved for behind-wall use. ProLock fits everything, everywhere. No adaptations, modifications, or tools; ever.
