Description
External centering ring with Perbunan O-ring, aluminium, DN 10/16 KF is a vacuum flange accessory for KF small-flange connections used in laboratory and technical vacuum systems. The aluminium ring is fitted with a Perbunan O-ring and provides external centering for DN 10/16 KF joints, supporting alignment and sealing when assembling or maintaining small-flange vacuum lines. This component from manufacturer WELCH is intended as an accessory or spare part for apparatus that rely on KF geometry in research, analytical, and industrial laboratory setups. Supplied as one piece, it matches common DN 10/16 KF interfaces where an aluminium external centering ring with elastomer sealing is specified. Perbunan (NBR) O-ring material is suited to many general vacuum applications involving standard laboratory gases and process conditions. Use this centering ring when building, modifying, or servicing KF vacuum plumbing that requires reliable external centering and a compatible aluminium–Perbunan sealing combination at the DN 10/16 size.

Questions about External Centering Ring with Perbunan O-Ring, Aluminium, DN 10/16 KF
What is this article?
External Centering Ring with Perbunan O-Ring, Aluminium, DN 10/16 KF 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.
