Description
Reducing adapter KNS 24/29 → HNS 14/23 is a laboratory glassware transition fitting designed to link components that carry different standard ground joint sizes. It features a cone joint NS 24/29 paired with a socket joint NS 14/23, allowing a direct reduction from the larger NS 24/29 interface to the smaller NS 14/23 socket. Such step-down adapters are essential in multi-neck flask assemblies, distillation trains, reflux systems and vacuum lines where progressive joint-size changes keep the glass train compact and correctly aligned.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.
The piece has a net weight of 0,017 kg and is supplied as a single unit, adding only modest mass while preserving mechanical stability. It belongs to the category of standard ground joint reducing and transition pieces commonly stocked for modular laboratory setups. Made by Witeg in Germany, the adapter follows the Normschliff conventions familiar to research, industrial and educational laboratories across Europe. Typical uses include organic synthesis, solvent recovery, sample preparation and teaching demonstrations that require a dependable, interchangeable connection between mismatched NS joints without additional intermediate fittings.

Questions about Reduction adapter ST 24/29-> ST 14/23
What is this article?
Reduction adapter ST 24/29-> ST 14/23 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
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.
