Description
Valve stopcock PE 12,7 mm straight-through stopcock is a compact polyethylene shut-off fitting designed for simple, reliable flow control in laboratory tubing lines. The straight-through (Durchgangshahn) design provides an unobstructed path when open, supporting clear media transfer in aqueous and many common laboratory fluid circuits. Hose barbs with an outer diameter of 12,7 mm allow secure connection to matching flexible tubing, while the PE body offers a lightweight, corrosion-resistant alternative to metal valves for routine bench and apparatus work. Maximum operating pressure is specified at 0,3 bar, making the unit suitable for low-pressure gravity feed, gentle pumping, and general laboratory distribution rather than high-pressure process service. Supplied as a single piece with a net weight of 0,016 kg, the stopcock is easy to integrate into temporary setups, teaching labs, and modular fluid paths. Categories such as valves, conical stopcocks, valve cocks, and shut-off valves reflect its intended use for isolation and on/off control. This PE valve stopcock from manufacturer Witeg combines straightforward geometry with practical barb sizing for everyday laboratory fluid handling where chemical resistance of polyethylene and low-pressure ratings are appropriate.

Questions about Valve tap PE 12.7mm through tap
What is this article?
Valve tap PE 12.7mm through tap is the article on this page. Luminix Health distributes Witeg 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.
