An adapter for an expandable hose is an apparatus used to connect an expandable hose to other fluid management tools. The apparatus is also configured to prevent leakages in multi-channel expandable hoses. An objective of the apparatus is to provide a connection for expandable hoses. The apparatus is designed to prevent leakage between expandable hoses and the apparatus. A threaded connector enables attachment of the expandable hose to other hoses. Another unit fits inside the inner channel of an expandable hose, while a third part surrounds the inner channel of the expandable hose. An annular fastener secures the outer channel of the expandable hose to the inner channel. A cover or housing may be added to protect components from damage due to external stimuli. Altogether, the apparatus enables a user to securely attach an expandable hose to a spout, faucet, spicket, another hose, or a variety of other devices.

A hose connector has: a cap, a connecting pipe and an assembly pipe. The cap has an inner ring and an outer ring, and the inner ring is provided with an inner threaded hole. The cap further has a socket hole connected with the inner threaded hole, the outer ring is provided with an outer threaded section. The connecting pipe has an inserting portion at one end and a first threaded portion at another end. The inserting portion has a neck section and a stopping ring. The inserting portion is disposed in the socket hole of the cap. The stopping ring comprises at least one protrusion facing the groove. The assembly pipe has a through hole and a convex ring at one end and a second threaded portion at another end. The second threaded portion of the assembly pipe engages with the inner threaded hole of the cap.

A hose connector has a first connecting joint, a second connecting joint, and a connecting duct. The first connecting joint comprises an inner neck rim having an inner threaded aperture and a containment space connecting to the inner threaded aperture. The first connecting joint further comprises a threaded outer wall, and a bottom surface of the neck rim has a plurality of engaging grooves. The second connecting joint comprises a hollow base having a neck section connected to a lip, and the neck section is configured for insertion in the containment space of the first connecting joint. A top surface of the lip has a plurality of engaging protrusions pushing against the neck rim or engaging with the engaging groove. The connecting duct comprises an outer threaded section and an enlarged flange, and the connecting duct is mounted through the neck section and the lip.

A hose connector has: a head portion, at least one connecting bolt, and a tightening ring. The head portion has a flow channel with at least two open ends, and at least one of the open ends is provided with a threaded portion. The connecting bolt has an inner threaded section engaging the threaded portion of the open end of the head portion, an opening of the connecting bolt has a stopping portion. The tightening ring has a groove configured to accept the stopping portion, a clasping end is formed adjacent to an outer edge of the groove and engaging an outer wall of the stopping portion, a convex ring is formed at another end of the tightening ring and pushing against the stopping portion.

Coaxial fluid elements that utilize fluid pressure to aid in creating a sealed conveyance of two separate pressurized fluid streams. A coaxial fluid fitting provides a fluid-pressure assisted seal on a coaxial fluid transmission element. Coaxial fluid transmission elements allow two separate fluid flows within the same transmission element: one fluid flow through an interior core region, and a second fluid flow through an exterior annulus region. The fluid flows are separated by an internal wall, fully contained by an external wall, with structural members connecting the two walls. The fluid-pressure assisted coaxial fluid fitting accepts a coaxial fluid transmission element, providing seals between the two fluid flows as well as to the surrounding environment. The interior seal is fortified by situating a higher pressure fluid in the exterior annulus region, providing an inward sealing force without the use of a mechanical sealing aid. This enables transmission systems of pressurized fluids that are smaller in size and contain fewer points of failure, compared to standard systems with single fluid stream transmission elements and fluid transmission systems containing other multi-lumen transmission elements.

A garden hose with an outer flexible sheath of spirally wound and linked turns of sheet material, an inner tube of flexible polymer inside the sheath and end couplers with nipples press fit into ends of the tube and connector mechanisms connecting the couplers to the outer sheath. Each connector mechanism has inner and outer press fit shells at the end of the sheath, with flared ends separated by a washer.

A hose fitting (10) includes a nipple (12) with a first end that is insertable into a hose and a second opposite end (22), nipple mating threads (38) located between the first (18) and second ends (22), and a shoulder (42) located between the mating threads and the second end (22) and that projects radially outward relative to the nipple (12) mating threads. A nut (16) is positioned over the second end (22) of the nipple (12). A shell (14) is positioned over the first end of the nipple (12) and includes shell mating threads (48), wherein the shell is threaded onto the nipple (12) by a threaded connection of the nipple mating threads (38) and the shell mating threads (48). The shoulder (42) operates to prevent further rotation of the shell (14), and the resulting torque locks the shell (14) in place and provides a seal against leakage from the fitting assembly. The nipple (12) includes a planar surface (40) that extends from the mating threads (38) to a second planar surface (26) that meet to form the shoulder (42).

A fluid circulation device having at least one fluid circulation tube, a first coupling sealingly coupled to a first end of the tube and a second coupling sealingly coupled to a second end of the tube in such a way as to allow the circulation of fluid between said two couplings via the tube. The device further has separate electronic elements. The tube has at least one conductor track extending along an outer surface of the tube. The track is suitable for transmitting at least one signal and arranged to engage with the abovementioned electronic elements.

A clamp device for a barb member having a barbed region for disposing within an end of a flexible tube having an outer surface. The clamp device includes a flexible member including a body having a plurality of finger members compressible between a first resting position and a second clamping position; at least one of the flexible finger members having a radially inwardly extending tooth; the body having a through bore and an outer surface comprising threads; the flexible member being slidable over the barbed region and the outer surface of the flexible tube; a compression member having a body having a through bore and an inner surface including threads; the compression member being slidable over the flexible member; wherein upon threadingly engaging the compression member with the flexible member, the compression member compresses the finger member against the barb member.

A pipe joint includes a joint body formed with a through hole therein along an axial direction, and having male threads and an extending shaft portion formed on one end side thereof; and a nut member formed with an insertion hole through which a tube member is inserted, and having female threads formed therein that screw-engage with the male threads. Annular projections are formed on an outer circumferential surface of the extending shaft portion, and the tube member, which is expanded in diameter, is gripped between the annular projections and an inner circumferential surface of the nut member.
