A flanged cylindrical metallic item designed to be used on tubing to back up the flared end and to provide a bearing surface for the coupling nut, thereby reducing wear on the tubing flare. The inside diameter of the flanged end is countersunk to form a seat for the flare when assembled to a mating fitting.
