A hose connector for joining flexible hoses is comprised of a tubular pipe body with at least one insertion portions made of a shape memory alloy (SMA) or other shape memory material that has a memorized shape. The insertion portion is located on at least on one end of the tubular pipe body and has an outer diameter smaller than an interior diameter of the flexible hose in a martensite state. The insertion portion is inserted into the interior diameter of the flexible hose and the memorized shape is recovered with the application of heat, wherein the outer diameter of the insertion portion becomes larger than the outer diameter of the flexible hose sealing the outer diameter of the insertion portion against the interior diameter of the flexible hose.

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 hose assembly, preferably a garden hose assembly, including a fabric jacketed tube that is lightweight, durable and versatile. The tube is radially expandable when pressurized by a fluid, such as water, but does not increase in length. The two layer construction of the hose assembly allows for storage in relatively compact spaces, similar flow rates, approximately one-half the weight, and improved maneuverability when compared to conventional hose constructions. In one embodiment the jacket is formed around the tube in a continuous process that welds a fabric, preferably using hot air, into the jacket. The welded joint forms a region of jacket that is preferably about twice the thickness of the rest of the jacket. This thicker region results in a stiffer section of jacket that makes the hose more controllable and consistent in use.

A hose connector (5) which can be fixed to the hose end region of a flexible hose (6) and includes an outer part (7), which surrounds the hose end region, and an inner part (8), which can be inserted into the clear cross section of the hose. The inner part (8) is in the form of a hollow rivet and is deformable between an initial form, which can be inserted into the clear cross section of the hose at the hose end region, and a widened form, which sealingly and fixedly clamps the at least one hose between the inner part (8) and the outer part (7). A hose line that can also be formed for example as a two-chamber or multi-chamber hose line is provided. Moreover, a method for producing a hose connector on the hose end region of a flexible hose is provided.
