Beschreibung
Adapter flange KF-Swagelok DN 25, 12 mm is a vacuum interface component that joins a KF small flange of nominal size DN 25 with a 12 mm Swagelok-style tube connection. It allows laboratories to couple standard KF vacuum hardware to compatible Swagelok tubing without improvised transitions, supporting clean, repeatable links in analytical, process, and general laboratory vacuum setups. The KF DN 25 side mates with matching small-flange clamps, centring rings, and seals, while the 12 mm Swagelok end accepts corresponding tube fittings for process lines, instrumentation, or pump accessories. Supplied as a single piece, the adapter fits spare-part and accessory inventories for vacuum pumps, manifolds, and modular laboratory assemblies. This KF-to-Swagelok transition is available from manufacturer WELCH for users who need a defined DN 25 to 12 mm interface in vacuum or gas-handling systems. Typical applications include integrating KF vacuum components with Swagelok tubing runs, replacing worn connection parts, and creating compact transition points in laboratory vacuum layouts. It is classified among accessories and spare parts for laboratory equipment and should be paired with matching DN 25 KF hardware and 12 mm Swagelok fittings of the corresponding nominal size for correct system assembly.

Questions about Adapter Flange KF-Swagelok DN 25, 12mm
What is this article?
Adapter Flange KF-Swagelok DN 25, 12mm is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Other instruments & spare parts, in Präzisionsinstrumente.
Some instruments do not sit cleanly in one measuring principle, and every instrument eventually needs a spare: a lamp, a fuse, a seal, a knob. The spare has to be the part for that model. A near match is a different part. Calibration of the instrument, once it measures, belongs with EURAMET, BELAC and the BIPM.
