A swage fitted end connector for high pressure large diameter reinforced flexible rubber hose utilizing sine-wave locking of the reinforcement and particularly suited to the petrochemical and drilling industries. Two embodiments of the connector for use with wire reinforced thin internal tube hose are disclosed: one with a diameter of 3-inches and for burst pressures up to 20,000 psi and the other for a diameter of 5-inches and for burst pressures up to 18,000 psi. All of the connectors will withstand the rated burst pressure of the hose without pumping off or leaking thus any hose that utilizes the device will fail before the connector pops off the hose. The connectors are designed to meet or exceed the new API temperature ranges and new API flexible specification levels which became effective in October 2006.

A plug-in connector assembly for connecting lines for pressurized fluids includes a plug-in connector receptacle having a plug-in opening on a plug-in side, in which plug-in opening a receiving cutout is arranged, a plug-in connector with a plug-in section which can be plugged into the plug-in opening of the plug-in connector receptacle, and a locking spring which is arranged on the plug-in connector receptacle. An anti-rotation element is insertable into the receiving cutout of the plug-in connector receptacle and can be accommodated therein in a fixed manner. The plug-in connector has on its outer side an anti-rotation groove extending in the longitudinal direction, which forms along with the anti-rotation element tongue and groove connection, such that the plug-in connector is secured against rotation relative to the plug-in connector receptacle.

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.
