Abstract: A hydraulic hose coupling, and method of assembling such to a hydraulic hose in a no-skive fashion. This is accomplished in many ways, some of which include the provision of a plurality of hose retention and sealing zones within the coupling, each of which include various combinations of radially inwardly directed barbs and radially inwardly and outwardly directed surface features on the inner stem of the coupling. With specific regard to the zone primarily directed to sealing, it includes a radially inwardly directed barb which works in conjunction with a straight cylindrical surface flanked by first and second radially inwardly directed recesses.

Abstract: A coupling assembly for use with a wire-reinforced elastomeric hose member includes a stem member defining at least one groove and the groove includes first and second walls, a bottom portion and a pair of shoulder portions separated by a width and a shell member at least partially enclosing said stem member and defining at least one axially extending barb member. The barb member includes a tip portion having first and second edge portions. The tip of the barb member is sized relative to the shoulders in said groove to transfer force developed by deflection of the reinforcement wire to compress a liner of the hose at the shoulders through the barb edge portions corresponding to a swaged state of the shell and stem members.

Abstract: A hydraulic hose coupling, and method of assembling a coupling to a hydraulic hose are disclosed. The hydraulic hose and coupling assembly is designed to attach a coupling to a hydraulic hose in a no-skive fashion. Moreover, it does so with greatly enhanced sealing and retention capabilities relative to the currently available products. This is accomplished in many ways, some of which include the provision of a plurality of hose retention and sealing zones within the coupling, each of which include various combinations of radially inwardly directed barbs and radially inwardly and outwardly directed surface features on the inner stem of the coupling. With specific regard to the zone primarily directed to sealing, it includes a radially inwardly directed barb which works in conjunction with a straight cylindrical surface flanked by first and second radially inwardly directed recesses.
