JOHN GUEST ProLock CTS Fittings

The ProLock range is specifically designed to speed up installations and provide additional peace of mind. These fittings audibly click and display visible alignment arrows to indicate a secure connection. They don't require any tools, clamps or glue to install, reducing installation times by more than 40%. This makes ProLock fittings ideal for use in water softener/conditioner systems and virtually any OEM type of application involving joining solutions. Plus, it's code-approved for behind-the-wall use.
How it works: ProLock click-to-lock fittings have a collet with stainless steel teeth that grip the pipe when fully inserted and include an o-ring to provide a permanent, leak proof seal. When twisted into place, the locking cap locks the pipe in place securely.
