The present invention relates to a tube connector assembly which may comprise a body provided with a through cavity extending in an axial direction, a ring adapted to be mounted at the periphery of a useful portion of the tube and provided, at one of its ends, with a support surface adapted to receive a curved end portion of the tube, a nut adapted to be screwed onto the body so as to compress the curved end portion of the tube against a receiving surface in the axial direction via said ring, and an annular receiving part forming the receiving surface and removably mounted on the body.

Fluidic connection assemblies, ports, unions and other components are provided that are well-suited for use in HPLC and UHPLC, as well as in other analytical instrument systems. Such assemblies, ports, unions and components can be biocompatible.

The assembly (1, 10) for irrigation, comprises a first and a second hose (2, 3) and comprises at least one connector (4, 5, 50) equipped with an attachment unit (4) adapted for the removable connection with tools for irrigation or water dispensers. The connector (4, 5, 50) comprises a first connection element (43) coupled to an end of the first hose (2) and a second connection element (51, 52), distinct from the first element (43) and coupled to one end of a second hose (3).

A gardening fluid connection device contains a body including multiple retainers, a resilient element, and a fitting sleeve including multiple spaced engagement teeth. The resilient element abuts against the body and the fitting sleeve. The body includes a stop rib, and the multiple spaced engagement teeth are pushed by the resilient element to abut against the stop rib. The body includes at least one retaining element, each retaining element is located on a first side of each spaced engagement tooth, and a width of each spaced engagement tooth is equal to a rotation distance of the fitting sleeve, hence the fitting sleeve is rotated reciprocatingly to open or close of the gardening fluid coupling device by using the stop rib, each retaining element, each spaced engagement tooth and the resilient element, and each retaining element is stopped when moving to a second side of each spaced engagement tooth.

A connector for a flexible non-metallic conduit is provided. The connector may include a gland nut for receiving the conduit, and a gland ring within the gland nut. The gland ring may be sized to extend around the conduit. The connector may further include a body threadably secured to the gland nut, and a ferrule disposed within the body, wherein the ferrule includes a first keying feature coupled to a second keying feature of the body to cause rotation therebetween, and wherein the ferrule is inserted partially into the conduit. In some embodiments, the gland nut is not directly physically coupled to the conduit, so the gland nut may slide over the conduit towards/away from the body. In some embodiments, during assembly, the body and the gland nut may be rotated together to cause external threading of the ferrule to engage an inner wall of the conduit.

A compression-type fitting system for quick connection of two conduits. The system includes a compression body configured to receive a first conduit and a second conduit therein. The system includes a compression lock nut to engage an outer surface of the compression body. Upon tightening, a continuous ring within the compression body facilitates forming a seal between the compression body and the first conduit.

The reusable sealing connector device for a flexible tube comprises a tubular element (2), a clamping sleeve (3), predisposed to be associated coaxially with said tubular element (2) and a clamping ferrule (4), predisposed to cooperate with the clamping sleeve (3) for clamping the flexible tube inserted on the tubular element (2), internally to said clamping sleeve (3).

A joint is devised for connection to an internal tube of a longitudinally extensible hose. The joint includes a sleeve and a tubular insert. The sleeve includes an axial channel for receiving the internal tube. The axial channel includes a diameter-wise smaller section and a diameter-wise larger section. The tubular insert is inserted in the internal tube so that the tubular insert and the sleeve clamp the internal tube. The tubular insert includes an axial passageway, an annular bulge and an annular flange. The axial passageway extends coaxially with the axial channel. The annular bulge is formed on a middle section of the tubular insert and adapted for pressing the internal tube against an wall of the diameter-wise larger section of the axial channel. The annular flange is formed at an end of the tubular insert and adapted for contact with an end of the sleeve.

An apparatus comprising a sleeve that comprises a tubular portion, a receiving portion, and a coupling portion. The tubular portion has an outer diameter that is substantially equal to an inner diameter of a flexible hose such that the tubular portion is capable of being inserted within the flexible hose. The receiving portion extends outward from the tubular portion to thereby define a channel between the receiving portion and the tubular portion for receiving an end portion of a flexible hose. The coupling portion is for coupling the sleeve, and thereby, the flexible hose, to a component.

An apparatus comprising a sleeve. The sleeve has an outer surface and a flange extending from the outer surface. The flange has a first surface for engaging an edge of first flexible hose and a second surface for engaging a union. The first surface of the flange has a radial length substantially equal to a thickness of the edge of the first flexible hose. The sleeve counteracts a deflection of the first flexible hose and the second flexible hose into a flow path created through the first flexible hose and the second flexible hose when the first flexible hose and the second flexible hose are coupled together using the union, the sleeve, and a pair of fittings.
