Clamp Tools, or Cinch Tools, are used to connect PEX pipes to each other or to a PEX fitting. It works by clamping down on a clamp ring around the PEX pipe. Unlike the crimp method, this connection method can be reassembled without cutting the PEX pipe. PEX Clamp Tool features a ratcheting, mistake-proof mechanism that prevents tool jaws from opening while the connection is being done. This saves the need for gauging and checking connections for errors.
