FASTLOCK fittings install quickly and easily with FASTLOCK press jaws, which are compatible with most press tools on the market. There’s no need for threading dies, pipe sealants, or pipe wrenches. FASTLOCK fittings reduce stress on joists and hangers during installation. FASTLOCK fittings are available in ½ to 2 in. and are IAPMO and NSF 61-4 certified for use with water, HVAC, and compressed air.
