Marketing InformationEnsure pipes are securely installed with Water-Tite® plastic half clamps with pre-loaded nails. Designed to support copper and PEX tubing (not recommended for CPVC) and available in sizes that fit either 3/8 in or 1/2 in pipe, these plastic half clamps isolate piping from wood framing. They are impact-resistant to 0 deg F (-18 deg C) and are capable of withstanding continuous maximum temperatures of up to 160 deg F (71 deg C). Each half clamp comes with a pre-loaded nail for quick installation.
