Description
3-Way stopcock with solid NS plug NS 14,5 is a precision laboratory glassware component designed for controlled multi-path fluid routing in chemical and analytical setups. It features a T-bore configuration with a solid ground joint plug and an integrated bent tube connection, enabling reliable diversion or isolation of liquid or gas streams. The bore diameter is 1,6 mm, supporting fine flow regulation while the over-rotation-proof threaded stopcock lock secures the plug against unintended movement during operation. Manufactured to DIN 12554 and supplied in the 8 × 100 mm format, this stopcock from manufacturer Witeg suits standard conical joint systems of NS 14,5. The solid NS plug provides a durable sealing surface for repeated use in vacuum or pressure-assisted apparatus. Typical applications include synthesis lines, distillation manifolds, gas-handling trains and general laboratory plumbing where a compact three-way valve is required. Net weight is 0,061 kg per piece, offered as a single unit for straightforward integration into existing glass assemblies. The robust construction supports everyday laboratory handling without compromising joint integrity or flow path accuracy.

Questions about Stopcock, three way, solid plug
What is this article?
Stopcock, three way, solid plug 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.
