A Specialized Fitting and a Method of Manufacture for swaging hose couplings to high pressure, high temperature reinforced rubber hose having a corrugated or smooth plastic/nylon/elastomer or metal lining (inner tube). The hose couplings include a stem having first hose grippers extending from and along a length of the outer surface; elastomeric sealing members located around and disposed along a length of the outer surface of the stem; and a ferrule attached to the stem adjacent ensuring a labyrinth seal between the inner tube and the hose coupling.

A multi-lumen hose connector nipple and a multi-lumen hose equipped therewith. The multi-lumen hose connector nipple includes a nipple basic section through which a plurality of separate fluid conduits extend in each case between a first and a second nipple connector side, a plurality of hose lumen plug-in sockets integral with the nipple basic section, which sockets extend juxtaposed on the first nipple connector side with an intermediate hose lumen wall accommodation space left therebetween, wherein a socket interior space of each of the hose lumen plug-in sockets is assigned to a respective one of the fluid conduits and opens out axially, and a socket strutting structure within the socket interior space of at least one of the hose lumen plug-in sockets.

A fitting (30) for fluid communication with a fluid conduit includes a first fluid conduit connection portion (42), a second fluid conduit connection portion (42), a header (60) disposed axially between the first fluid conduit connection portion and the second fluid conduit connection portion, and a socket (70). A fluid fitting may include a nipple (40), a radial projection (48) connected to the nipple, and an axial protrusion (120) extending from the radial projection. The axial protrusion may be configured to protrude into an axial end of a fluid conduit (80). A fluid fitting may include a fluid conduit connection portion (42) and a dynamic tip (130) connected to an end of the fluid conduit connection portion. The dynamic tip may be configured to expand in response to an increase in fluid pressure.

A system includes a flexible pipe that includes a liner surrounding a bore of the flexible pipe, a reinforcement layer surrounding the liner, and a shield layer surrounding the reinforcement layer. The system also includes a pipe fitting coupled to an end of the flexible pipe and a securing mechanism at least partially disposed in an opening in at least one of the liner layer, the shield layer, or both of the flexible pipe. The securing mechanism is configured to engage with the reinforcement layer of the flexible pipe when the pipe fitting is coupled to the end of the flexible pipe.

A wall faucet is disclosed which has an elongated section of a PEX tube inserted into the water inlet pipe of the wall faucet. The PEX tube is capable of expanding should there be water in the water inlet pipe during freezing temperatures thereby preventing the water inlet pipe from bursting.

An improved end connector for a high-pressure reinforced hose that is subjected to high frequency of pressure cycles and that provides for a low compression deformation of the reinforced hose is discussed. This unique end connector has a stem and ferrule that includes a gripper or cable lock region near a coupler, or outboard end and a substantially smooth length on an outer diameter (OD) of the stem and ferrule that extends from about the gripper region to a hose receiving, or inboard, end.

The system also includes a pipe fitting coupled to an end of the flexible pipe and a securing mechanism at least partially disposed in an opening in at least one of the liner layer, the shield layer, or both of the flexible pipe. The securing mechanism is configured to engage with the reinforcement layer of the flexible pipe when the pipe fitting is coupled to the end of the flexible pipe.

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 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 connection has: a tubular body with a first end and a second end; a shrink sleeve arranged around the first end of the tubular body for crimping and thereby clamping a hose end on the first end of the tubular body; and an adhesive layer arranged on the outer surface of the first end of the tubular body and at least enveloping the first end in tangential direction.
