In an example, a fitting assembly configured to visibly indicate nut tightness when coupling a first component to a second component is disclosed. The fitting assembly comprises a nut comprising a threaded portion and a chamber portion, wherein the chamber portion comprises one or more through-holes. The fitting assembly also comprises an indicator slidably disposed within the chamber portion, a retainer assembly disposed within the chamber portion and configured to interlock with an inner surface of the nut, and a spring disposed within the chamber portion between, and engaging, the indicator and the retainer assembly. The retainer assembly is configured to interface with the spring to retain the spring within the chamber portion. The fitting assembly is configured to receive the first component and the second component such that, when the nut is rotated, a visibility of the indicator through the one or more through-holes changes.

Flow through connectors and pressure sensing devices as well as their methods of use are described. In some instances a pressuring sensing device may include a ceramic body with a flow path extending through the ceramic body and at least one non-ceramic body attached to the ceramic body. The at least one non-ceramic body may include one or more attachment features formed therein and the flow path extends through the at least one non-ceramic body as well.

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 cold plate assembly for cooling heat-generating electrical component on a circuit board is disclosed. The cold plate assembly includes a cold plate with a bottom contact surface to thermally contact the heat-generating electrical component. The cold plate has an inlet coupler on an opposite top surface to receive coolant; an internal conduit to circulate the received coolant; and an outlet coupler on the opposite top surface to return the coolant. A flexible metal inlet tube is fluidly connected to the inlet coupler to supply coolant. A flexible metal outlet tube is fluidly connected to the outlet coupler to return coolant.

Example aspects of riser support assembly and a method for adjusting a riser support assembly are disclosed. The riser support assembly can comprise a riser support pipe and a mount extending from a side of the riser support pipe, the mount configured to engage a mounting surface and to selectively adjust a height of the riser support assembly relative to the mounting surface.

A connector assembly for connecting a corrugated tube with a braid mounted on the periphery of the hose to a metal connector, comprises an inner sleeve mounted on the corrugated tube, and an outer sleeve mounted on the inner sleeve, the inner and outer sleeve cooperating with each other to hold the braid between the inner and outer sleeves. The inner and outer sleeves have respective inner and outer tapered surfaces. One of the inner and outer tapered surfaces has one or more portions projecting toward the other of the inner and outer tapered surfaces.

In order to be able to join a pipe member and a pipe joint more firmly than before without using welding, a joining structure airtightly or liquid-tightly joins an outer peripheral surface of the pipe member and an inner peripheral surface of a cylindrical member to be mounted on the pipe member, and the pipe member and the cylindrical member are made inseparable by an annular protrusion formed on the inner peripheral surface of the cylindrical member.

A mounting apparatus for mounting together a first pipe and a second pipe end to end. The mounting apparatus a first abutment member mountable on the first pipe at a predetermined distance from the end of the first pipe and a second abutment member mountable on the second pipe at a predetermined distance from the end of the second pipe. The apparatus further includes a sealing member locatable between the ends of the pipes and a tightening arrangement for urging the first and second abutment members mounted on the first and second pipes towards one another and thereby providing a seal between the pipes.

A valve coupling for joining pipe elements includes a valve housing surrounded by coupling segments. Projections extend from the segments and engage channels in the valve housing. Engagement between the projections and the channels guides the segments as they are drawn together to engage the pipe elements and secures the valve housing between the segments.
