Description
3-way stopcock PTFE thread NS 14,5 is a laboratory stopcock with T-bore for controlled multi-path flow in glass apparatus. It uses a ground joint size NS 14,5 together with an NS-PTFE plug and a threaded stopcock lock for secure seating during operation. Bent tube connectors measure 8 × 100 mm and the bore diameter is 1,6 mm, in accordance with DIN 12554. Supplied as a single piece from manufacturer Witeg, the unit has a net weight of 0,056 kg. The PTFE plug and threaded retention support reliable sealing at the NS 14,5 interface, while the T-bore configuration enables three-way routing of liquids or gases in standard laboratory setups. Bent tube ends of 8 × 100 mm facilitate connection to adjoining glassware, and the 1,6 mm bore defines the internal flow path. Built to DIN 12554 dimensions, this stopcock suits assembly work where an NS 14,5 PTFE-plug three-way valve with threaded lock is required. The compact 0,056 kg construction keeps the fitting practical for benchtop glass systems.

Questions about Stopcock, three-way PTFE ST 14,5
What is this article?
Stopcock, three-way PTFE ST 14,5 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.
