ABSTRACT:
An improved hose fitting is disclosed. The hose fitting has a body member with a coupling nut at one end. A socket member surrounds the body member and together they define an opening for receiving a hose. A plurality of projections extend inwardly from the interior surface of the socket member. Each projection includes an inner side or surface, an outer side or surface and a tip surface connecting the inner surface and the outer surface. The tip surface extends a distance "x" from the interior surface of the socket member. An enlarged radius defines a circular outer surface on each projection. The radius is between 0.5x and 1.3x and is preferably approximately "x".
