Supplied as one piece, it suits installation or replacement on laboratory vacuum pumps, manifolds, gauges and process lines that use the KF standard. This external centering ring is practical wherever aluminium hardware combined with a Viton seal is required for DN 10/16 KF connections. It supports consistent assembly of small-flange vacuum systems common in analytical and research laboratories and forms part of the accessories and spare-parts range for lab equipment. From manufacturer WELCH, the ring is aimed at users who need a ready DN 10/16 KF external centering ring with Viton O-ring for maintenance or new builds without altering the existing flange interface.

Questions about External Centering Ring with Viton O-Ring, Aluminium, DN10/16 KF
What is this article?
External Centering Ring with Viton O-Ring, Aluminium, DN10/16 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.
