A flanged cylindrical item having a sharp cutting surface on the inside diameter at the end opposite the flange. The cutting edge, in use, is designed to imbed in the tubing due to pressure exerted when the outside diameter of the sleeve is forced into and against an angular seat. This firmly attaches the sleeve to the tubing and the flanged end then serves as a bearing surface for the coupling nut to bring the tubing into the mating fitting.
