The Homewerks PEX175 1/2 in. Pex Stainless Steel Clamps offer 360° seamless fastening and meet or exceed ASTM F-2098 requirements. Due to their heavy-duty 304 series steel construction as well as their step-less design and uniform compression sealing, these cutting edge clamps were designed primarily for PEX (cross-linked polyethylene) piping and PE-RT (polyethylene raised temperature) tubing but have numerous alternate uses. Manufactured with patented non-slip crimp lobes on both ends of the ear, Murray's heavy-duty seamless PEX clamps are the best at preventing mis-crimps and slip-offs as well as holding fast under the worst conditions. Murray Corporation's clamping products are subjected to rigorous environmental testing to ensure maximum reliability and longevity in adverse conditions.
