Description
Tee ISO-K/KF DN 100/40 is a stainless steel vacuum fitting for laboratory and technical vacuum systems. This T-piece joins ISO-K and KF flange interfaces, supporting reliable branching of vacuum lines in research and process setups. Built from stainless steel, it provides mechanical durability for repeated assembly in demanding environments. The DN 100/40 size pairs a large ISO-K connection with a DN 40 KF port, giving flexible layout options when adapting pumps, chambers, and instrumentation. Offered as one piece from manufacturer WELCH, the tee integrates into modular ISO-K and KF flange assemblies used across laboratory equipment. As an accessory and spare part for lab apparatus, it helps configure vacuum plumbing without custom metalwork. The hybrid ISO-K/KF design suits facilities that standardise on both flange families and need a compact branch point. This stainless steel tee is intended for professional vacuum technology where dimensional compatibility with DN 100 and DN 40 interfaces is required.

Questions about Tee ISO-K/KF, Stainless Steel, DN 100/40
What is this article?
Tee ISO-K/KF, Stainless Steel, DN 100/40 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.
