A device for a computing system is disclosed. The device includes a body, a socket, and a connector. The body includes a panel and an internal conduit. The connector extends from the panel. The connector is removably coupled to the socket. The connector includes an outer end and an inner end. The connector also includes a nut that has an exterior surface mating with a corresponding interior surface of the socket, and a tubular inlet. The connector also has a sleeve with an internal bore and an external surface abutting the tubular inlet of the nut. The internal conduit is coupled to the inner end of the connector to circulate cooling liquid through the body. The nut includes an angled portion and the sleeve includes a flared portion for assisting in securing the nut and the sleeve in the internal conduit.

A tubing nut fastener having elements that are partially rotatable with respect to each other. In between the rotatable elements, engagement members (e.g., balls) are captured within interior channels. The partially rotatable elements include permanent markings or other non-removable visual indicators, which varies spatially depending on whether the tubing nut fastener is in a torqued state or an un-torqued state, thereby providing a visual indication of the status of the tubing nut fastener.

A plug for connecting capillaries includes at least one capillary tube, at least one sealing, and at least one pressure piece. The capillary tube includes a first inner diameter and an open end section. The sealing includes a second inner diameter, a first end section and a shape adapted to seal the open end section of the capillary tube when connected. The pressure piece is adapted to exert at least axial pressure and/or force to at least a part of the sealing. The pressure piece is also adapted to host the first end section of the sealing in abutment with the open end section of the capillary tube so that the capillary tube and the sealing are aligned.

A fluidic connection assembly and methods for quickly connecting or disconnecting a tube to a port by hand and without the use of tools. A body is adapted to receive a tube therethrough, and may have at least two sides which are hinged. Each of the hinged sides has corresponding latching portions or projections located near a lower end of the body. These projections are adapted to fit into a port or other fitting and be securely held in place. The assembly may include a tube extending through a body and through a spring located between the end of the body and the end of the tube, whereby the spring exerts a force directly or indirectly against the end of the tube and against the body, thus holding the tubing securely and sealingly engaged in the port when the assembly is connected. The body may further comprise an additional body or an adapter, and/or a cap and latch. A second spring may be used to push a projecting member into a groove or notch of an adapter when an end of the adapter is inserted into one end of the latch or the body. The fluidic connection assembly is useful in analytical instrument systems, such as for in vitro applications and/or in high pressure applications, among other things, and may be used in methods for connecting, or disconnecting, tubing or a fluidic connection assembly from a port or other fitting or connection.

A torquing tool for rotating bolts connecting a pipe flange in a subsea environment, comprising a first guide for guiding movement of the torquing along a pipe, a socket for engaging a first bolt, a shaft for transferring torque from a motor to the socket, and a first protruding member for insertion between the pipe and a second bolt of the pipe flange, to prevent the torquing tool from rotating due to counter torque created while applying torque to the first fastener. The torquing tool can further comprise a second protruding member adjacent the socket, wherein the second protruding member can be inserted between the pipe and a third bolt of the pipe flange. The torquing tool can further comprise an angled shaft for transferring torque from the motor to the socket, wherein an axis of rotation of the motor is different from an axis of rotation of the socket.

A system for further filtering a liquid extract material after an initial extraction process. In an embodiment, the system includes a semi-rigid filter cup that is substantially cylindrical, the filter cup having a top and a bottom, wherein the top is oriented to receive filter media prior to a filtration process, and material to be filtered during the filtration process. The filter cup includes an integrated deformable flange at the top of the filter cup, an integrated top o-ring that is integrated into the top of the integrated deformable flange and an integrated bottom o-ring that is integrated into the bottom of the integrated deformable flange.

A fitting for fluidic coupling in a chromatography system includes a compression screw including an axial bore, a threaded portion, and a drive end, a tube assembly including a tube sleeve and an inner tube disposed through the sleeve, the tube sleeve and the inner tube each extending to an endface of the tube assembly, the tube sleeve including an outer surface, a seal body extending between a first endface and a second endface, the first endface abutting the endface of the tube assembly, the seal body including an outer surface, and a collar secured to the outer surface of the tube sleeve and the outer surface of the seal body. Other Fittings, Methods of manufacture of fittings, and methods of fluidic coupling are further disclosed.

A push-fit type fitting that can be used to connect a pipe to either another pipe or a variety of other fittings. The fitting includes a visual indicator that provides a visual confirmation to the user once the pipe has been correctly retained in the device.

Couplings for joining pipe elements have segments with attachment members with faces which contact one another when the segments are properly installed on the pipe elements. Each segment has one or more shrouds and recesses positioned along the faces. The shrouds on one segment are received within respective recesses on the other segment. The shrouds block the line of sight toward the central space which the segments surround and which receives the pipe elements. Index markings on the segments show visual inspection points to confirm proper engagement between the segments and the pipe elements.
