Description
Reducing 4-way cross DN 40/25 KF is a stainless steel vacuum fitting for laboratory and technical systems built around the KF flange standard. This reducing cross provides four connection points, combining a DN 40 interface with a DN 25 KF port so neighbouring line sizes can be joined in a single cross geometry. Fabricated from stainless steel, the component supports reliable integration into vacuum manifolds, pump lines, and instrument assemblies where mechanical strength and corrosion resistance are valued. It is supplied as 1 pc and is classified among accessories and spare parts for laboratory equipment. The reducing 4-way cross from manufacturer WELCH uses the established KF clamping principle for DN 40 and DN 25 flanges, helping configure branched vacuum routes without non-standard adapters. The explicit DN 40/25 KF marking makes it straightforward to pair with matching flanges, seals, and clamps already in use. Select this stainless steel reducing cross when a four-port transition between DN 40 and DN 25 KF connections is needed in research, analytical, or process laboratory vacuum setups.

Questions about Reducing 4-Way Cross, Stainless Steel, DN 40/25 KF
What is this article?
Reducing 4-Way Cross, Stainless Steel, DN 40/25 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.
