Description
Reducing adapter KNS 60/46 to HNS 45/40 is a ground-joint transition piece that joins laboratory glassware of two different standard taper sizes in one compact fitting. It combines a cone NS 60/46 with a socket NS 45/40, allowing a larger male joint to couple securely to a smaller female joint in distillation trains, reaction assemblies, and vacuum apparatus. The single-piece unit has a net weight of 0,103 kg and is intended for modular glass setups where rapid, leak-resistant size conversion is required without custom glassblowing. Produced by Witeg, this reducing adapter belongs to the established normschliff transition range used across chemical synthesis, analytical sample preparation, and teaching laboratories. Standardised cone and socket geometry ensures interchangeability with common European ground-joint systems, so flasks, condensers, receivers, and adapters can be reconfigured quickly. Categories such as transition pieces and normschliff reducers highlight its role in flexible apparatus design. Suitable for research, quality-control, and educational environments that routinely mix NS sizes, the adapter supports reliable, repeatable glassware trains while remaining simple to install and clean between experiments.

Questions about Reduction adapter ST 60/46 -> ST 45/40
What is this article?
Reduction adapter ST 60/46 -> ST 45/40 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.
