An adapter for connecting conduit to a threaded component such as for connecting a PVC conduit to a threaded pipe includes a tube having a threaded end and a conduit-receiving female end to receive the conduit, the female end having a length of at least 70% of the total length of the adapter. The female end includes an elongated chamber having a length of at least two inches and at least as long as an outer diameter of the adapter. In other aspects the adapter includes an inner transition portion having a tapered inner surface, and in further aspects the adapter includes a grip region having recesses and such that an installer grasping the adapter can grip the adapter with a thumb and multiple fingers while pressing the adapter into a palm of the hand.

A fluidic device includes a planar structure constituted by a plurality of laminated layers and accommodating a fluid channel extending up to a surface of the planar structure, and a female adapter piece configured for a fluid-tight accommodation of a male adapter piece having a fluid conduit. The the female adapter piece is connected or connectable with the planar structure so that, when the male adapter piece is accommodated in the female adapter piece, the fluid conduit is brought in fluid-tight fluid communication with the fluid channel. The fluid channel is exposed to the female adapter piece at a lateral surface of the planar structure at which the laminated layers are exposed.

The polymeric pipes reinforced with a metal casing are used for transporting oil and gas, acids, alkali products, drinking water and industrial water, and also in the transportation of aggressive and neutral pulps. A metal-containing polymeric reinforced pipe includes a welded metal casing and a polymeric matrix having an amorphous-phase-based molecular structure. The metal-containing polymeric reinforced pipe is produced by extrusion moulding with simultaneous feeding of a polymer melt and the reinforcing metal casing into the mould cavity, followed by intensive cooling of the internal and external surfaces of the pipe being moulded. The invention increases the quality and endurance limit in the radial direction of the metal-containing polymeric reinforced pipe, productivity of the process for manufacturing the pipe, and also the strength and technological effectiveness of a pipeline constructed from the pipes produced.

A pipe connector fitting comprising a body comprising a longitudinal axis, a throat, opposed side walls, an upstream end and a downstream end, a bore defined by the body, a plurality of internal metal threads disposed within the body, an elongate gasket comprising a non-round cross-section, and a gasket retention area defined by the body, sized and dimensioned to accept and retain the gasket when the gasket is non-compressed and fully compressed and the gasket is never allowed to escape the gasket retention area into the throat of the body, the gasket retention area comprising a flat gasket retention surface disposed perpendicular to the longitudinal axis of the body, the gasket disposed within the gasket retention area, wherein, when a threaded male fitting is threadedly disposed within the body, the threaded male fitting can be rotated 360 degrees while remaining continuously fluid tight for pressures in excess of 300 psig.

A tubing retention device for retaining a T-shaped tubing assembly includes a base member having a first tubing recess, a second tubing recess oriented perpendicular to the first tubing recess, and first and second relief shelves disposed at opposite ends of the first tubing recess and recessed relative to the bottom surface of the first tubing recess. A movable locking element is configured to move between an unlocked first position and a locked second position and is configured to lock a T-shaped tubing assembly in the tubing retention device in the locked second position. A fluid pump includes a housing and such a tubing retention device mounted to the housing. A T-shaped tubing assembly may be secured within a such a retention device by positioning the T-shaped tubing assembly in the first and second tubing recesses, and moving the locking element from the unlocked first position to the locked second position.

A connector for a hose transferring a medium, comprising an inner part, wherein the inner part comprises at a first end a first section comprising an opening for accommodating a hose and a second section comprising a duct arranged between an inner base of the opening for the hose and a second end of the inner part that is opposite of the first end, wherein the first section has a greater outer diameter than the second section; and an outer part, wherein the outer part comprises a thread surrounding the second section and a grip surrounding the first section, wherein the outer part is fixed rotational movable around the inner part between a flange at the inner part's second end the first section with the greater outer diameter.
