Copper Tube Flange
It is a tool that allows the mechanic to shape the copper tube so that, when it is applied, a complete seal can be made in the placement of pipe joints. In valves, registers etc. The flange is composed of a base and a clamp containing a screw threaded into its body. At the end of the screw is a rotating conical tip. This, when inserted in the tube, allows the rotation of the screw without friction in the tube to be flanged.
