The invention relates to an intermediate holder (3) which on the external circumference thereof has at least one holding means (5) for fastening the intermediate holder (3) in a water outlet (4) of a sanitary outlet fitting (1), and on the internal circumference thereof at least one fastening means (6) for releasably fastening a sanitary functional unit (2). One approach to a solution according to the invention provides that the intermediate holder (3) is manufactured from one material strip and the holding means and fastening means (5, 6) of said intermediate holder (3) are configured as formed lugs of the material strip that at the one lug end of said lugs by way of a bent region are connected to the material strip and that by way of the opposite other free lug end of said lugs protrude beyond the circumference of the material strip.

A pipe coupling is described comprising an outer tubular part (1) with threads inside, an inner tubular part (10) with threads outside, and a sleeve (5) where on a first half of the sleeve there are external and inner threads which fit in the threads of the outer and inner tubular parts, respectively, so that the sleeve (5) can be screwed into the outer tubular part (1) while it is simultaneously screwed onto the inner tubular part (10) and the outer and inner tubular parts are firmly connected to each other through the threads on the sleeve (5).

A water pipe includes a pipe body (1), a woven layer (2) sleeved around the pipe body (1), a first joint assembly (3) arranged at one end of the pipe body (1) and secured to the pipe body (1), and a second joint assembly (4) arranged at another end of the pipe body (1) and secured to the pipe body (1); the woven layer (2) includes bamboo charcoal fibers and polypropylene filaments. The woven layer (2) is sleeved around the pipe body (1) and is not connected with the pipe body (1), and the woven layer (2) includes bamboo charcoal fibers and polypropylene filaments. Bamboo charcoal fibers have the functions of resisting bacteria and removing peculiar smell and can effectively prevent the generation of bacteria on the water pipe and the emission of peculiar smell when the water pipe is used in humid outdoor environments.

A flange assembly for supporting a cable has a flange body and an armor retainer. The flange body and the armor retainer are configured to support a cable by compressing an armor layer of the cable against the armor retainer. The armor retainer and the flange body are separate pieces, that are removably attachable to one another.

An enhanced seal may comprise an inner portion and an outer portion. The inner portion may comprise an inner cylindrical portion and an inner annular portion. The outer portion may comprise an outer cylindrical portion and an outer annular portion. The inner portion may be made of a harder material than the outer portion and may provide support to the outer portion.

A pipe-fitting device according to the present invention includes a fitting body, a fixing nut, and a collet. A first end of the fitting body is rotatably connected to an outer circumferential surface of a first pipe, and a second end of the fitting body surrounds an outer surface of a second pipe. A first end of the fixing nut is rotatably connected to an outer circumferential surface of the fitting body, and a second end of the fixing nut surrounds the outer surface of the second pipe. The collet is provided inside the fixing nut and presses the second pipe when the fixing nut is rotated and tightened. The collet includes a seating portion provided inside the fixing nut, a bending portion in which a bending groove is formed, a pressing portion which presses and seals the second pipe, and a protecting portion which protects the pressing portion.

A light-emitting hose assembly includes: a hose having a water passage extending therethrough. A first connector includes a connector seat, which has an end coupled to an end of the house and an opposite end formed with an internal thread, and a light-emitting device. The connector seat includes water flow channel extending therethrough. The water flow channel is in communication with the water passage of the hose. The light-emitting device is arranged in the water flow channel of the connector seat to receive water to flow therethrough to generate electricity and emit light that transmits out of the connector seat. A second connector is coupled to an opposite end of the hose.

A curved plastic faucet contains: a body, an arcuate tube, connector, and a supply head. The body includes a connection member. The arcuate tube includes an inflow segment, an outflow segment, an arc-shaped section extending to circumference length of the inflow segment from the outflow segment, and an arcuate water conduit which has an imaginary arc line being an arcuate section of a circle and a length of the arcuate section is not more than of the circle, wherein a cross section of the arcuate water conduit proximate to the inflow segment is not more than that of the outflow segment, and an outlet is defined adjacent to a lower end of the outflow segment. The connector includes an inlet and at least one stop ring. The supply head includes a guide space and a second screwing portion mating with a first screwing portion.

There is provided a connection structure for fire extinguishing system piping with which stable sealing performance can be obtained, due to screw engagement, by connection work carried out even by an unskilled worker and with which secure engagement of the connection portion can be confirmed easily.

In a connection structure for fire extinguishing system piping in which a male piping member is connected to a connection opening portion of a multi-port joint T by screwing a male thread and a female thread together, the male piping member includes a joint cylinder having a protruding portion that is inserted deeper into the connection opening portion than the female thread. The male piping member also includes the sealing members and that seal the engagement portion between the male thread and the female thread to prevent water leakage into the inside of the connection opening portion. The male piping member includes a step portion, and the connection opening portion includes a step portion. The connection structure further includes an indicator that engages the step portions and in a state in which the male piping member and the connection opening portion are connected together.

Described are apparatuses, devices, and systems implementing seals for separation devices. An apparatus for a separation device may include an end nut shaped to be positioned on one of an inlet side and an outlet side of the separation device. The end nut may be further shaped to mate with a connecting fitting. The apparatus may further include a face seal having a device side and a fitting side. The face seal may be positioned, at least in part, in the end nut on the device side of the face seal. The face seal may be positioned to interface with the connecting fitting on the fitting side of the face seal upon the end nut being mated with the connecting fitting. The apparatus may also include a face seal bore of the face seal being axially alignable with at least one of an inlet and an outlet of the separation device.
