Description
Tee, stainless steel, DN 40 KF is a three-way vacuum fitting intended for laboratory and technical vacuum systems based on the KF (Klein Flange) standard. Fabricated from stainless steel and sized to DN 40 KF, it provides a branch junction between matching flanges, lines, and apparatus. The item is supplied as one piece and is classified among accessories and spare parts for laboratory equipment. In pump manifolds, chamber connections, and instrumentation lines, a stainless steel tee at this nominal diameter supports robust mechanical coupling where DN 40 KF hardware is specified. This fitting from manufacturer WELCH is meant to slot into existing KF assemblies rather than serve as a complete instrument on its own. Consistent DN 40 flange geometry aids pairing with clamps, centring rings, and seals of the same series. Choose it when a durable metal T-piece is needed in research, analytical, or process vacuum setups built around KF DN 40 components.

Questions about Tee, Stainless Steel, DN 40 KF
What is this article?
Tee, Stainless Steel, DN 40 KF 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.
