Description
Metal vacuum hose, stainless steel, DN 40 CF, 250 mm is a stainless-steel metal vacuum hose for laboratory and technical vacuum connections. It is specified with a DN 40 CF flange interface and a length of 250 mm, giving a compact metal hose section for linking vacuum components where CF geometry is required. Intended as an accessory or spare part for laboratory equipment, the hose supports installation and replacement work on pumps, chambers, manifolds, and related apparatus that use DN 40 CF connections. The stainless-steel construction provides a durable metal conduit suited to routine vacuum line service in research and analytical settings. Supplied as 1 piece, the item is ready for direct integration into existing or new vacuum assemblies. This metal vacuum hose from manufacturer WELCH offers laboratories a clearly defined stainless-steel hose option in DN 40 CF format at 250 mm length. Technicians can deploy it wherever a short flexible metal vacuum hose is needed to maintain continuity of the vacuum path without improvised tubing. The combination of stainless steel, DN 40 CF sizing, and 250 mm length makes it a practical stock item for facilities that standardise on CF-flanged metal vacuum accessories.

Questions about Metal Vacuum Hose, Stainless Steel, DN 40 CF, 250mm
What is this article?
Metal Vacuum Hose, Stainless Steel, DN 40 CF, 250mm is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in PVC, PTFE & other tubing, inside Tubing, hoses & fittings, in Labware.
PVC is the flexible everyday tube for water and mild aqueous liquids. PTFE is the stiff, almost inert tube for solvents. Other polymers sit between them. The bore, the wall and the chemical resistance are the specification, and the tube is cut to length.
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.
