Description
Flexible coupling DN 16 KF, 120 mm is a flexible vacuum connection component for laboratory apparatus and technical vacuum lines. It combines a DN 16 KF flange interface with an overall length of 120 mm, enabling a short flexible section between matched KF components while preserving the nominal flange geometry. The part is supplied as one piece and is classified among accessories and spare parts for laboratory equipment. In vacuum manifolds, pump connections and instrument setups, a flexible coupling of this type helps accommodate minor misalignment and reduces mechanical stress on rigid tubing or glassware joints. This flexible coupling from manufacturer WELCH is intended for integration into standard KF vacuum assemblies used in analytical, process and research environments. Its compact 120 mm length suits bench-scale and instrument-level installations that need a defined flexible link without changing the DN 16 KF interface. Laboratories can stock the unit as a replacement or expansion element within existing KF infrastructure. Clear dimensional designation of flange size and length supports straightforward selection against system drawings and spare-part lists.

Questions about Flexible Coupling, DN 16 KF, 120mm
What is this article?
Flexible Coupling, DN 16 KF, 120mm 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 Matériel de laboratoire.
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.
