A gasket for preventing the separation of a pipe joint formed between plastic pipes such as pipes manufactured from PVC. The invention provides an internally restrained pipe joint including a bell with a substantially V-shaped annular groove. The annular groove includes a front radial wall and a rear radial wall and a gasket seated in the annular groove. The gasket includes an inner radial face, an opening defined by the inner radial face and an outer radial face with a front radial section located adjacent to the front radial wall of the annular groove and a rear radial section located adjacent to the rear radial wall of the annular groove. A plurality of toothed, rigid restraining segments is at least partially embedded in the gasket.

A prefabricated part comprises a concrete body that has the form of a pipe section with two pipe ends and a pipe inner side. The pipe inner side is lined at least in some areas by a lining made of plastic material connected to the concrete body, and at least one of the pipe ends is covered at least in some areas by a molded part made of plastic material connected to the concrete body. At least the pipe end, which is covered at least in some areas, has a connecting joint in order to connect the pipe end to a pipe end of a further prefabricated part. The lining consists of a thermoplastic material and the molded part consists of a thermosetting plastic. The lining and the molded part are connected to each other in a sealed manner.

Pipe connector for coupling a first-end pipe and a second-end pipe that includes intermediary attachment connectors for each of the first-end and second-end pipes. The attachment connectors include O-ring slots machined into an external perimeter surface and a movable sleeve that engages with the intermediary attachment connectors to form a seal between the O-ring slots and an internal perimeter surface of the sleeve.

A pipe joint with a socket, and a pipe fitted into the socket. An annular seal is compressed between the socket and the pipe. The seal is electrically conductive and resiliently flexible. The socket or the pipe has a recess which houses the seal. The recess has a ridge in a base of the recess and the seal has a groove which extends around a radial periphery of the seal. The ridge fits into the groove to fool proof the installation, such that a standard non-conductive O-ring seal is more difficult to install in error.

A shower head adapter includes a body part, which has one side connected to the inner circumferential surface of the inlet side of a main shower head body and the other side connected to a hose. The shower head adapter also includes a first circular groove formed along the outer circumferential surface thereof and a main body connecting part, which has an end on the other side protruding inwards from the inner circumferential surface thereof. A part of the inner circumferential surface is coupled to the outer circumferential surface of the inlet side of the main shower head body. A snap ring is inserted in the first circular groove. The diameter of the outer circumferential surface of the snap ring is larger than the diameter of the protruding inner circumferential surface of the main body connecting part.

A conveying device for use in the field of plastics has a frame and a weighing cell connected to the frame. A separating unit is suspended from the weighing cell. A first coupling is connected to the frame and connects a vacuum source to the separating unit. A second coupling is connected to the frame and connects a conveying line for goods to be conveyed to the separating unit. At least one of the first coupling and the second coupling has a first coupling part connected to the separating unit and a second coupling part connected to the frame, wherein the first and the second coupling parts do not contact each other in a region of no contact. At least one sealing element is provided to seal the region of no contact between the first and the second coupling parts.

Hose barb fittings and apparatuses described herein provide increased fluid-flow rates for cooling loops used for thermal control in computer system. A hose barb fitting comprises a fluid-flow passage that extends through the hose barb fitting from a first opening to a second opening. The ratio of the cross-sectional area of the fluid-flow passage to the cross-sectional area of the hose barb fitting is between 0.4 and 0.7, inclusive. When the hose barb fitting is fully seated within a housing structure, a specialized gasket acts as both a radial seal and a face seal. Also, a flange extending from the housing structure engages with a flange extending from the hose barb fitting to prevent the hose barb fitting from being unseated.
