A connector assembly (608) for a length of corrugated tubing (601) having an inner corrugated element (602) and an outer flexible sheath layer (603). The connector assembly (608) comprises a fitting (609) including a fluid-flow passage and an abutment surface (612) for the corrugated tubing (601) to seat thereon; axial loading means operably connectable to the fitting (609), the axial loading means including a connector (613) and a collet (610), the collet (610) having a radially inward protruding clamping element (611) for insertion into a trough (606) of the inner corrugated element (602), and a sheath-contact portion (625) for engaging the outer sheath layer (603), so that, when the connector (613) moves the collet (610) into engagement with the fitting (609), the collet (610) causes the corrugated element (602) to move onto the abutment surface (612) whilst maintaining engagement with the outer sheath layer (603). The sheath-contact portion (625) is axially positionable between the inner corrugated element (602) and the outer sheath layer (603) of the corrugated tubing (601), in use.

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.

A valve is disclosed with a clamp mechanism that accepts interchangeable outlet connections. The interchangeable outlook connections may have different sealing geometries, where different sealing geometries are specified to be used with different gases. For use with a particular gas, the valve may be configured with the interchangeable outlook connection with the sealing geometry that is appropriate for that gas.

A coupling system for interconnecting a tube to a valve body is provided. The valve body has a body portion and a nipple extending from the body portion, and the nipple has a threaded external surface and an internal wall defining a bore. The coupling system further includes an adapter having opposing first and second ends, a nut defining a hole through which the first end passes, and a compression fitting located between the nipple, the adapter, and the nut such that when the nut is tightened onto the nipple, the compression fitting inhibits removal of the adapter from the valve body. The adapter defines a passageway extending from the first end to the second end, wherein the first end is received in the bore and the second end is configured to couple to the tube. The nut has an internally threaded surface configured to engage the threaded external surface.

A pipe joint structure contains: a body, a connection ring, and a screwing nut. The body includes a hollow channel defined therein, a connecting tube surrounding around the hollow channel and having at least one open end, and a coupling section arranged adjacent to an end portion of an outer wall of the connecting tube. The connection ring includes an inner joining diameter for connecting with the coupling section. The screwing nut includes an internal orifice, an outer diameter of which is greater than the body and the connection ring. The internal orifice has first inner threads formed around inner wall thereof and has a limiting rib arranged on one end of the internal orifice facing to the body, wherein an outer diameter of the internal orifice is greater than an outer diameter of the body and is smaller than an outer diameter of the connection ring.
