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 coupling device is provided. The coupling device may include a stem having a first end, a second end, a groove, and a threaded portion. A first engagement member may be disposed over the stem between the first end and second end. The first engagement member may be movable relative to the stem. An inner sealing member may be disposed in the groove. When the first engagement member is in a first position, the inner sealing member may be retained in the groove, seal against a surface of the stem, and may not be removed. When the first engagement member is in a second position, the inner sealing member may be retained in the groove, does not seal against the surface of the stem, and may be removed. The coupling device may include a washer, an outer sealing member, and a second engagement member disposed over the stem.

An electrically conductive hose cutting clip has at least one end tab that is shaped to provide a cutting edge for penetration of the inner layer(s) of a multiple layer fluid conveyance hose when it is clipped onto a fluid connector and the hose is installed on the fluid connector by forcing it onto the connector. The cutting action by the cutting clip provides for a relatively low resistance electrical connection between an electrically conductive layer of the hose and the fluid connector. This can be used to provide a signal path from a sensing element on or in the hose to a system electronic component.

A hose coupling for attachment to an end portion of a hose. The hose coupling may include a fitting, a termination attachment, and an end termination. The fitting may be attachable to the end portion of the hose. The fitting may include a ferrule and a stem. The ferrule may be attached to the stem. The termination attachment may be attached to the fitting in opposing relationship to the end portion of the hose. The end termination may be associated with the termination attachment. In some examples, the end termination is threaded, welded, integrally formed, integrally machined, or otherwise associated with the termination attachment.

A mounting group for a press fitting is provided. The mounting group includes cylindrical pressing sleeve with a pressing area and a stop ring fixed to a first axial end of the pressing sleeve and limiting the pressing area in an axial direction of the pressing sleeve. The stop ring has a first inner contour on a side opposite the pressing area and as a first circular segment and a second circular segment, which extends over a smaller part of the first inner contour than the first circular segment. The stop ring has a constant cross-section in the region of the first circular segment and an element arranged in the region of the second circular segment which projects inwardly beyond the constant cross-section of the first circular segment and causes a tilting of an axis of symmetry of the pressing sleeve.

A hydraulic coupling system is configured to couple a hydraulic hose to a hydraulic cylinder and includes: a compressive adapter assembly including: a first adapter portion configured to receive a portion of the hydraulic hose, and a second adapter portion configured to engage an inlet tube of the hydraulic cylinder, wherein a first tube portion of the inlet tube of the hydraulic cylinder is configured to be received within a portion of the hydraulic hose; and a compressive sleeve assembly configured to engage the compressive adapter assembly and radially compress the first adapter portion of the compressive adapter assembly onto an outer surface of the portion of the hydraulic hose, thus compressing an inner surface of the portion of the hydraulic hose onto the first tube portion of the inlet tube of the hydraulic cylinder.

A connection end-piece of a flexible pipe includes an end vault extending along a central axis; an outer cover fixed to the end vault and defining, with the end vault, a reception chamber for receiving an end section of the armor elements of the flexible pipe; at least one annular member applied externally to the armor elements of the flexible pipe, the annular member being at least partially accommodated in the reception chamber between the armor elements and the outer cover. The annular member applies a radial tightening pressure higher than 100 bars onto the armor elements toward the central axis of the flexible pipe.

Processes for securing a fitting to a hose end, and a hose assembly produced thereby. The fitting has an interior portion, exterior portion, and cavity therebetween. An end of the hose is located within the cavity and compressed between the interior and exterior portions. The exterior portion of the fitting has at least first and second circumferential crimped portions axially spaced apart along the fitting length, and first and second portions of the hose are compressed within the first and second circumferential crimped portions. The exterior portion of the fitting has an annular-shaped bubble portion between the first and second circumferential crimped portions. The bubble portion has a diameter larger than diameters of the first and second circumferential crimped portions, and the hose has a portion radially expanded into an annular-shaped cavity surrounded by the bubble portion as the hose is compressed at the first and second portions thereof.
