Description
PTFE one-way stopcock with olives for tubing I.D. 7 mm and a bore of 4 mm provides straightforward shut-off control for laboratory fluid lines using flexible hose of 7 mm internal diameter. The PTFE construction delivers broad chemical resistance for aqueous and many organic media in analytical, preparative and general laboratory apparatus. Olive ends facilitate direct connection to matching tubing, while the 4 mm bore sets the internal flow cross-section through the valve. Designed as a one-way stopcock, it is well suited to simple on/off duties in bench manifolds, transfer lines and sampling setups where a compact PTFE valve is preferred. Supplied as a single piece from manufacturer Brand, the component aligns with laboratory valve, plug-cock and shut-off applications and is not specified as a sterile product. Low mass and small pack dimensions ease storage and retrofit into existing hose systems. Select this model when your tubing I.D. is 7 mm and you require a chemically inert PTFE one-way stopcock with a 4 mm bore for reliable everyday fluid control.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Stopcock, PTFE, one-way with nozzles, f. tub. inner dia. 7 mm bore 4 mm
What is this article?
Stopcock, PTFE, one-way with nozzles, f. tub. inner dia. 7 mm bore 4 mm is the article on this page. Luminix Health distributes Brand 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.
