Abstract

A fitting assembly comprises a male coupling having a male thread and an aperture defining an inner circumferential surface of the male coupling. The inner circumferential surface includes a plurality of spaced apart grooves. A tail piece is at least partially received in the aperture of the male coupling. A hose is received and compressed in a space formed between the inner circumferential surface of the male coupling and an outer circumferential surface of the tail piece. The hose is deformed into the plurality of the spaced apart grooves formed in the inner circumferential surface of the male coupling to form an interference fit therebetween.

Abstract

A hose coupling utilizing a main hollow body and an expandable inner sleeve and an intermediate end of a hose which is securely held in place upon radially outward expansion of the sleeve.
