Description
PVC spiral hose KF25/500 is a flexible laboratory vacuum hose made of PVC with an embedded spiral reinforcement, combining collapse resistance with good handling for vacuum line connections. It features KF DN 25 small-flange ends and a working length of 500 mm, making it suitable for linking vacuum pumps, manifolds, rotary evaporators and other apparatus that use standard KF interfaces. The internal spiral supports the tube wall under reduced pressure while the PVC wall remains flexible enough for routing in crowded fume hoods or instrument racks. Supplied as a single piece with a net weight of 0,800 kg and gross weight of 1,000 kg, the hose originates from Germany and is offered by manufacturer VACUUBRAND within the laboratory materials range. Its KF DN 25 geometry ensures direct compatibility with common small-flange vacuum components used in research and analytical laboratories. The reinforced construction helps maintain an open flow path during continuous or intermittent vacuum service, simplifying temporary setups as well as more permanent vacuum plumbing. This spiral hose provides a practical, ready-to-use tubing element for everyday vacuum applications where flexibility, flange standardisation and mechanical stability are required.
This article is part of PVC, PTFE & other tubing, in Tubing, hoses & fittings.

Questions about PVC tubing with spiral, KF DN 25/500 mm
What is this article?
PVC tubing with spiral, KF DN 25/500 mm is the article on this page. Luminix Health distributes Vacuubrand 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.
