Stainless Steel Cinch Clamps are used to properly secure all PEX pipe fittings inside of a PEX pipe. A single tool can work with multiple PEX sizes. The Cinch Clamp is perfect for confined spaces due to its unique design, in which the ear of the clamp is pressed down by a PEX Clamp tool to apply pressure through the ring, and hold firmly around PEX piping. You will need a Clamp tool to make any connections. Canarsee offers a variation of sizes and all the tools necessary to make a perfect Cinch connection.
