Description
Adapter flange KF-Swagelok DN 25, 1 in. is a vacuum and laboratory connection component that joins a KF (NW) DN 25 flange interface to a 1 inch Swagelok-compatible fitting. The adapter provides a defined transition between standardised Klein-flange vacuum hardware and larger Swagelok-style tube or compression connections in a single piece. On the flange side it matches NW25 clamp geometry used with common KF clamps and centring rings; on the tube side the 1 in. Swagelok end aligns with corresponding tubing and fittings. Packed as one piece, it is intended for modular vacuum manifolds, instrument interfaces and laboratory gas or fluid lines where KF and Swagelok standards must be combined. Offered from manufacturer WELCH within accessories and spare parts for laboratory equipment, the part is identified by the DN 25 / 1 in. sizing so users can match flanges, clamps and tube diameters correctly. It suits research, analytical and technical laboratory configurations that require a robust KF-to-Swagelok adapter at this nominal size.

Questions about Adapter Flange KF-Swagelok DN 25, 1in.
What is this article?
Adapter Flange KF-Swagelok DN 25, 1in. 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.
