Beschreibung
Hose connector, stainless steel, DN 40 KF – DN 25 is a vacuum-line fitting that joins KF flange interfaces of different nominal sizes in laboratory and process vacuum systems. One side accepts a DN 40 KF connection while the other matches DN 25, allowing hose or tubing transitions without rebuilding the entire manifold. Stainless steel construction provides mechanical strength and corrosion resistance suited to routine vacuum pump lines, filtration setups, and apparatus maintenance. The KF (Klein Flange) geometry is widely used in research and industrial vacuum technology, so this adapter integrates cleanly with standard clamps and centring rings. Offered as a single piece from manufacturer WELCH, it serves as a practical accessory or spare part when reconfiguring, repairing, or expanding vacuum equipment. Laboratories that need a compact, durable transition between DN 40 KF and DN 25 ports can use this connector to keep systems modular and serviceable while preserving vacuum integrity under normal operating conditions.

Questions about Hose Connector, Stainless Steel, DN 40 KF - DN 25
What is this article?
Hose Connector, Stainless Steel, DN 40 KF - DN 25 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.
