A multi-fitting rotatable fluid connection apparatus comprising a fluid entry fitting and first and second fluid discharge fittings. The fluid entry fitting comprises a first end connector threaded for attachment to a fluid source, and first and second distribution connectors. The first fluid discharge fitting has a first intake connector which receives fluid from the first distribution connector. A first rotation member is coupled between the first intake connector and the first distribution connector such that the first fluid discharge fitting is rotatable about a first axis of rotation. The second fluid discharge fitting has a second intake connector which receives fluid from the second distribution connector. A second rotation member is coupled between the second intake connector and the second distribution connector such that the second fluid discharge fitting is rotatable about a second axis of rotation.

In an implementation, a hydraulic assembly comprising an end section of a hydraulic hose formed from a volume of material, the end section having a first outer diameter and an open end, is formed by molding a flange in the end section of the hydraulic hose, and threading an annular gasket onto the end section of the hydraulic hose between the flange and the open end of the hydraulic hose, and adjacent to the flange. The flange is formed in the volume of material, and has a second outer diameter greater than the first outer diameter. The molding of the flange may include applying heat to a mold, inserting the open end of the end section of the hydraulic hose into the mold, and thermally deforming a portion of the end section of the hydraulic hose to form the flange.

A fitting body includes a tubular end whose outer periphery has an external thread and whose inner periphery has an annular groove or protrusion. A sleeve connects a tube to the tubular end of the fitting body. A union nut includes a first axial end that receives the tube therein and a second axial end to be screwed onto the external thread of the fitting body. The fitting body includes first and second regulating portions extending in directions that intersect an axial direction of the fitting body to contact the union nut being screwed onto the external thread and then sharply raise torque to be transmitted through the union nut to a hand of a worker. When being screwed onto the external thread, the union nut contacts the first regulating portion and subsequently the second regulating portion.

A tube assembly including a cross-linked polyethylene tube having a radial projection and a coupler, and a method for forming the tube assembly. A forming assembly is configured to dispose the radial projection of the cross-linked polyethylene tube through the coupler after the completion of the cross-linking process.

A sealing arrangement includes: a first pipe and a second pipe, which are arranged substantially adjacent to each other in a flow direction and together form a line, the first pipe having a first end and the second pipe has a second end, the first end enclosing the second end at a radial spacing; and a sealing sleeve comprising a sealing material, the sealing sleeve being sealingly arranged under radial elastic preloading in a gap formed by the spacing and sealingly contacting an inner circumference of the first pipe and an outer circumference of the second pipe.

In an implementation, a hydraulic assembly comprising an end section of a hydraulic hose formed from a volume of material, the end section having a first outer diameter and an open end, is formed by molding a flange in the end section of the hydraulic hose, and threading an annular gasket onto the end section of the hydraulic hose between the flange and the open end of the hydraulic hose, and adjacent to the flange. The flange is formed in the volume of material, and has a second outer diameter greater than the first outer diameter. The molding of the flange may include applying heat to a mold, inserting the open end of the end section of the hydraulic hose into the mold, and thermally deforming a portion of the end section of the hydraulic hose to form the flange.

Technologies are described for devices and methods to couple a hose to another hose or apparatus. The device may comprise a first side with at least two barbed fittings, each configured to insert into a flexible hose to create a waterproof seal. A diameter of each barbed fitting may increase in size from a first end of the first side to a second end of the first side. The device may comprise a second side with at least two male fittings, each configured to threadly interact with threads of a female fitting to create a waterproof seal. A diameter of each two male fitting may increase in size from a first end of the second side to a second end of the second side. The device may comprise a separator rim attached to the second end of the first side and to the second end of the second side.

A tube assembly including a cross-linked polyethylene tube having a radial projection and a coupler, and a method for forming the tube assembly. A forming assembly is configured to dispose the radial projection of the cross-linked polyethylene tube through the coupler after the completion of the cross-linking process.

A pressure hose (1) for a water-carrying system is shown and described, especially for connecting sanitary taps or for connecting parts of the water-carrying system, having a corrugated inner hose (2) made of plastic, wherein at least one hose end (3, 5) of the pressure hose (1) is provided with a connecting piece (4, 6), designed such that it differs from the inner hose (2), for joining the pressure hose (1) to a complementarily designed connecting piece of a sanitary tap and/or a part of the water-carrying system. According to the invention, it is provided that the inner hose (2) and the connecting piece (4, 6) are formed as one piece and the inner hose (2) and the connecting piece (4, 6) are preferably produced via extrusion in a common extrusion process.

A drainage pipe connection tool for connecting two adjacent sections of corrugated, high density polyethylene (HDPE) drainage pipe or a section of HDPE drainage pipe to a collecting basin includes a first brace member, a second brace member with a tensioning member pivotally fitted thereto and straps extending between the first brace member and the second brace member. In use, the first brace member is fitted to one of the corrugated sections of HDPE drainage pipe or behind a female bell-shaped opening of the basin, and the second brace member is fitted to the adjacent section of HDPE drainage pipe. The straps are pulled taut to remove slack, and a lever of the tensioning member is operated to apply tension on the straps, urging the adjacent drainage pipe sections together or the pipe section into the open female bell of the basin.
