Abstract
A flareless tube fitting having a nose portion defining a sharp biting edge for sealingly retaining a tube end with a body member 11 of the fitting. Vibration forces acting on the tube end outwardly of the fitting are blocked from passing to the biting edge by a rounded support outwardly of the sleeve nose portion. The rounded support is formed by a tilting of a deflectible portion of the ferrule extending outwardly from the deformable ring portion and caused to be tilted so as to urge the ring portion radially inwardly into the tube end by the threaded advance of the nut member on the body member in the makeup of the fitting.
