A hollow conduit is provided. In another aspect, a quick connector, suitable to carry fluid therethrough, is made of layers of material, a light curable material and/or multiple built-up materials. Another aspect uses a three-dimensional printing machine to emit material from an ink jet printing head to build up a conduit.

A pipe joint for coupling to at least one pipe is disclosed in the present invention. The pipe joint includes a main body and at least one positioning socket. The main body has a runner and at least one opening communicated with the runner. The runner has an insertion area adjacent to the opening. The positioning socket has a head, an inserting portion, a pipe channel, a radial threaded hole and a bolt. The inserting portion is inserted into the runner via the opening. The pipe channel runs through the head and the inserting portion in an axial direction of the positioning socket. The threaded hole is formed on the head and communicated with the pipe channel. The bolt is adapted to engage with the threaded hole for abutting against the outer surface of the pipe.

A connector assembly includes a first connector, a compression member, a retainer, and a second connector. The first connector includes a first coupling portion, a proximal opening, and an annular inner surface extending from the proximal opening. The compression member includes an inner surface and an outer surface. The outer surface is configured to sealingly engage the annular inner surface of the first connector. The retainer includes a ring portion and a plurality of teeth. The ring portion includes a proximal end and a distal end. Each of the plurality of teeth extends from the distal end and is configured to engage the compression member. The second connector includes a second coupling portion and an engagement surface. The second coupling portion is configured to engage the first coupling portion. The engagement surface is configured to engage the proximal end of the retainer.

A duct coupler has a body with an inner wall with a first channel and a second channel formed in the inner wall, a first seal received in the first channel, and a second seal received in the second channel. The body has a first open end suitable for receiving a first duct therein and a second open end at an opposite end thereof suitable for receiving the second duct therein in longitudinal alignment with the first duct. The first seal is suitable for bearing on an outer surface of the first duct. The second seal is suitable for bearing on the outer surface of the second duct. The body fixedly locks the first and second ducts therein such that the ends of the ducts are adjacent to each other and such that the body forms a liquid-tight seal with outer surfaces of the ducts.

A quick-connector comprises a first body portion, a second body portion, and a ball valve. The first body portion defines a first fluid channel. The second body portion defines a second fluid channel. The second body portion is coupled to the first body portion such that the first fluid channel is aligned with the second fluid channel. The first fluid channel and the second fluid channel form a fluid channel extending through the quick-connector. The ball valve is positioned in the fluid channel extending through the quick-connector. Movement of the first body portion and the second body portion relative to each other causes the ball valve to move between a flow position and a sealed position. In the flow position, the ball valve allows fluid to flow through the quick-connector. In the sealed position, the ball valve prevents fluid from flowing through the quick-connector.

A disconnect assembly for operationally attaching a hose or other fluid conduit to a fluid inlet, and selectively decoupling the hose or conduit from the fluid inlet. In a first locked position, a fluid pressure seal is formed permitting pressurized flow of fluids through the disconnect assembly. In a second unlocked position, the hose or other fluid conduit can be quickly, safely and efficiently decoupled from the disconnect assembly such as, for example, during an emergency or unforeseen crisis. Following such decoupling, fluid is automatically contained and prevented from discharging into a surrounding environment.
