Description
PTFE three-way valve with Ø 4,5 mm hose nozzles and NW 2 mm bore is a compact laboratory shut-off and distribution component for fluid handling. Machined from solid PTFE, the body offers broad chemical resistance and exceptionally smooth actuation thanks to the material’s low-friction sliding properties. Blue polypropylene handles provide a clear, ergonomic grip for precise flow path selection. The valve withstands operating pressures up to a maximum of 1 bar and is suitable for vacuum service down to 5 mmHg, making it practical for both pressure and reduced-pressure setups. It is autoclavable, supporting repeated thermal sterilisation cycles in routine lab workflows. Supplied as a single piece from manufacturer Bürkle, this three-way PTFE valve with integrated hose barbs suits tubing connections in chemical, analytical and general laboratory installations where inert wetted surfaces and reliable, easy operation are required. Net weight is approximately 0,048 kg per unit.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about PTFE-valve, three-way, Ø 4,5 mm, NW 2mm, autoklav.
What is this article?
PTFE-valve, three-way, Ø 4,5 mm, NW 2mm, autoklav. is the article on this page. Luminix Health distributes Bürkle for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
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.
