A device for the sealed closing of an opening for one or more elongate parts to pass through includes a sealing and/or clamping element with at least two interacting first and second parts that are axially displaceable relative to one another, and a pressure contour acting axially onto the sealing and/or clamping element. A first axial displacement of the pressure contour and an axial displacement of the at least one second part relative to the at least one first part causes a first change in geometry of the at least one first part transversely to the displacement direction. Also, a further axial displacement of the pressure contour causes a further change in geometry of the at least one first part transversely to the displacement direction such that the opening is sealed around the one or more elongate parts passing therethrough.

Provided is a joint structure with which a pipe can be disconnected without moving the pipe in a longitudinal direction thereof, even if the pipe is not machined. A first sleeve has an inner cavity into which a pipe is inserted, and one end part of the first sleeve comes into contact with a joint body. A second sleeve has a hole into which the pipe is inserted, and one end part of the second sleeve comes into contact with the other end part of the first sleeve. A nut covers one end part of the joint body, the first sleeve, and the second sleeve, and the nut is threaded onto the joint body in a state of pressing against the surface of the second sleeve on the side opposite from the first sleeve.

Apparatus and method for mechanically attached connections of conduits may include a conduit gripping member, a drive member, and a seal member, the drive member causing axial movement of the conduit gripping member to indent into an outer surface of the conduit when the assembly is pulled-up, the drive member causing the seal member to form a zero clearance seal at a location that is axially spaced from the conduit gripping member. The zero clearance seal may comprise a face seal arrangement including a gasket, and the conduit gripping member may be a ferrule, ring or other device that can grip and optionally seal against the conduit outer surface. The assembly may include a sensing function for detecting or sensing a characteristic or condition of an assembly component or the fluid or both. In one embodiment, a body coupling member has a two piece construction of a main body and a conduit socket insert. A flared fitting embodiment is also provided. Sensing functions are also incorporated into fittings other than just zero clearance fittings.

Provided herein are exemplary connector assemblies including a conduit body having a conduit inner surface opposing a conduit outer surface, at least a portion of the conduit inner surface being a threaded portion. The connector assemblies may further include a compression ring extending from a first circumferential end to a second circumferential end, wherein the first circumferential end is complementarily engageable with the second circumferential end, wherein the compression ring includes a first axial end and a second axial end, and wherein the compression ring has a circumferential gap between the first circumferential end and the second circumferential end in an uncompressed configuration. The connector assemblies may further include a bushing positioned within the threaded portion of the conduit inner surface of the conduit body.

A connecting device, in particular in the form of a hose coupling, with two coupling parts (3, 5) which are connectable to each other and are releasable again from each other and of which the one (3) uses a securing device (51) to secure a connecting hose (1) which produces a fluid-conducting connection to a connecting channel (15) of the other coupling part (5) in the coupled state, and with a sealing system (37, 71) which has a sealing ring (37) which, arranged in the region of the free end (7) of a coupling part (3), surrounds the accommodated connecting hose in a sealing manner, is characterized in that the sealing ring (37) projects over the free end (7) of the one coupling part (3) outwards towards the environment by a pre-determinable axial excess length, with a sealing surface (39) for the connecting hose (1) being formed.

A vehicle shifter mechanism comprises a shift control member configured with an outer threaded portion proximate an upper end, and an inwardly tapered bore proximate the upper end. A shift lever is configured with an outwardly extending annular shoulder proximate a lower end. The annular shoulder has a tapered lower portion configured to register with the tapered bore of the shift control member. A locking nut is configured to fit over the shift lever and to mate with the threaded portion of the shift control member to compress the tapered lower portion of the annular shoulder to the tapered bore to fix the shift control member to the shift lever.

Described is a fitting for coupling fluidic paths which facilitates secure and low leak rate fluid flow through a fluidic path junction such as a junction in a liquid chromatography system or other chemical analysis instrument. Fluid containing various mixtures of chemical samples can pass through the junction at high pressure with little or no trapped residue remaining in a volume at the connection. According to various embodiments, a face seal is achieved between two separate fluidic path features. In some embodiments, the sealing of the fluidic paths is aided by the use of a compliant polymer seal. The seal facilitates intimate contact between adjacent surfaces and significantly limits or prevents the entry of fluid under high pressure into an unswept volume. Thus the risk of carryover and its adverse effect on measurements is reduced or eliminated.

A connector for the reciprocal connection of an end member of a water supply or of a sprayer with a flexible hose includes a tubular main body defining an axis and having a first end portion for coupling with the end member and a second end portion that includes an elongated spigot, on which an end of the flexible hose may be fitted, and further includes an abutment wall, from which the elongated spigot extends. The connector also includes a substantially tubular shaped ring nut placed peripherally to the spigot and reciprocally screwable with the main body, and an annular pressure element interposed coaxially between the ring nut and the spigot.

A pipe restraining system has first and second pipes. Each pipe has an axis and a groove adjacent an axial end thereof. A bushing bridges and hydraulically seals with the first and second pipes. First and second clamp rings removably attach the bushing to a respective one of the first and second pipes. When the pipe restraining system is assembled, axial tensile loads passing through the first pipe are transmitted through the first clamp ring, the bushing, and the second clamp ring to the second pipe. An axial distance between the first and second pipes remains substantially constant.

Provided herein are conduit couplings and connector assemblies suitable for wet locations. In some embodiments, a connector assembly includes a conduit, a compression ring extending around the conduit, and a connector body extending around a conduit outer surface, wherein the connector body including first and second ends. The connector body may further include an inner cavity and an internal stop, wherein the inner cavity and the internal stop define first and second sections. The connector assembly may further include a sealing ring within the inner cavity, wherein the sealing ring is directly adjacent the stop, a compression seal extending around the conduit outer surface, wherein the compression seal is in abutment with the first end or the second end of the connector body, and a friction ring extending around the conduit outer surface, wherein the friction ring is in abutment with the compression ring and the compression seal.
