Finish Jobs Faster

The John Guest Click-to-Lock Range has been designed with an audible click and visible alignment arrows to assure installers that a fitting is secure. Fittings are ideal for use in water softener/conditioner systems and virtually any OEM type of application involving joining solutions.

Click-to-Lock fittings have a collet with stainless steel teeth that grip the pipe when fully inserted, and an O-ring to provide a permanent, leakproof seal.

When twisted into place, the locking cap locks the pipe in place securely. No special tools, soldering, clamps or glue are ever required. Fittings reduce installation times by more
than 40% and are code-approved for behind-the-wall use.
