Description
Intermediate adapter, stainless steel, DN 16/16 KF, 60 mm is a vacuum flange component for connecting matching KF fittings in laboratory and technical vacuum assemblies. It provides a straight intermediate section with DN 16/16 KF interfaces and an overall length of 60 mm, allowing modular build-up of vacuum lines between pumps, manifolds, traps, and instrumentation. Made of stainless steel, the adapter is intended for routine laboratory vacuum work where durable metal KF clamp joints are required. This intermediate adapter from manufacturer WELCH is offered as a single piece within accessories and spare parts for laboratory equipment. It bridges two identical DN 16 KF ports without changing flange size, helping maintain a continuous vacuum path when a short extension or spacing piece is needed. The KF (Klein Flansch) geometry supports quick, demountable connections commonly used in analytical, research, and process setups. Select this stainless-steel intermediate piece wherever DN 16/16 KF alignment and a 60 mm length suit the layout of your vacuum apparatus or supporting hardware.

Questions about Intermediate Adapter, Stainless Steel, DN 16/16 KF, 60mm
What is this article?
Intermediate Adapter, Stainless Steel, DN 16/16 KF, 60mm is the article on this page. Luminix Health distributes WELCH 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.
