Description
Intermediate adapter DN 25/25 KF is a stainless steel vacuum component for laboratory equipment that uses KF flange connections. With a length of 125 mm, this intermediate adapter links two DN 25 KF interfaces in a straight run, supporting spacing and alignment needs in vacuum lines and apparatus. Stainless steel construction provides mechanical durability for routine laboratory vacuum work in research, analytical, and technical settings. Both ends follow the KF flange format so the piece can be integrated with standard clamp-style KF hardware without changing the nominal connection size. Available as one piece from manufacturer WELCH, the adapter serves as an accessory or spare part wherever an intermediate DN 25/25 KF stainless steel section is required. It fits modular vacuum manifolds, pump connections, and instrument vacuum paths that already rely on DN 25 KF geometry. Laboratories building or maintaining KF-based vacuum assemblies can use this intermediate adapter to complete or extend DN 25 runs while keeping flange dimensions consistent throughout the setup.

Questions about Intermediate Adapter, Stainless Steel, DN 25/25 KF, 125mm
What is this article?
Intermediate Adapter, Stainless Steel, DN 25/25 KF, 125mm 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.
