John Guest’s ProLock Contractor Pack features CTS fittings in a convenient sturdy box for any plumbing need. The fittings within the pack can be used with any combination of copper, PEX, or CPVC pipe without the need for any tools. Couplers, elbows and end caps in both ½” and ¾” CTS sizes are all included within the box. These lead-free fittings assure installers with additional security by providing users with an audible click and visible alignment arrows when twisted and locked into place. ProLock products are also code-approved, approved for behind-the-wall use and are UV-stabilized for outdoor use. The pack carries a 25-year warranty against defect in materials or manufacturing.
