Description
Quick disconnect coupling, male, is a straight hose connector for laboratory liquid-handling systems that need fast, secure line changes on larger small-bore tubing. This male coupling fits Ø 6,4 mm tubing and includes a shut-off function intended to limit fluid loss when the connection is opened. Supplied as a single unit weighing 0,004 kg, it suits bench-scale transfer lines, wash circuits, and modular hose assemblies used in general labware workflows. The straight geometry supports straightforward inline routing and simple alignment with matching female quick-disconnect components. Within the hose-connectors category for liquid handling, the part allows tool-free make-and-break joints so fluid paths can be reconfigured quickly for sampling, rinsing, or instrument supply. The coupling comes from manufacturer ROTH SELECTION for everyday laboratory use alongside compatible tubing. Its 6,4 mm interface, integrated shut-off, and modest mass make it a practical choice where slightly higher flow capacity and controlled disconnection behaviour are required in compact laboratory setups.

What is this article?
Quick disconnect coupling, male, straight, Ø 6,4 mm, with shut-off, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
