Description
Flexible coupling DN 63 ISO-K, 100 mm is a flexible vacuum connection component for laboratory apparatus and larger technical vacuum lines. It combines a DN 63 ISO-K flange interface with an overall length of 100 mm, offering a compact flexible section between matched ISO-K components while retaining the nominal flange geometry. The part is supplied as one piece and is grouped with accessories and spare parts for laboratory equipment. In vacuum manifolds, pump connections and instrument setups, a flexible coupling of this format helps accommodate slight misalignment and reduces stress on rigid pipework or chamber ports. This flexible coupling from manufacturer WELCH is intended for integration into standard ISO-K vacuum assemblies used in analytical, process and research environments. Its 100 mm length suits installations that need a short flexible link at DN 63 ISO-K without altering the flange standard. Laboratories can stock the unit as a replacement or expansion element within existing ISO-K infrastructure. Clear indication of flange size and length supports reliable selection against drawings and maintenance lists.

Questions about Flexible Coupling, DN 63 ISO-K, 100mm
What is this article?
Flexible Coupling, DN 63 ISO-K, 100mm is the article on this page. Luminix Health distributes WELCH 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.
