Description
Centering ring adaptor with Viton O-ring in stainless steel for DN 10/16 KF vacuum connections provides a compact interface piece for laboratory vacuum lines and apparatus. The adaptor geometry matches the familiar KF (ISO-KF) flange family at DN 10/16, enabling alignment and sealing between compatible components in pump manifolds, traps, gauges, and process attachments. A Viton O-ring supplies the elastomeric seal against the mating flanges, while the stainless-steel body offers mechanical stability for repeated assembly in everyday laboratory service. This accessory is available from manufacturer WELCH as a single-piece unit intended for spare-part and set-up use with laboratory equipment. It belongs to the accessories and spare-parts category for lab devices and supports clean, tool-friendly KF joint assembly when a centering ring with integrated seal is required. Specifying the DN 10/16 KF size at order ensures dimensional compatibility with existing small-flange vacuum hardware. The robust metal-and-elastomer construction is aimed at routine vacuum plumbing rather than specialised high-purity or ultra-high-vacuum metallurgy, making it a practical choice for general laboratory vacuum systems, service kits, and replacement of worn centering components.

Questions about Centering Ring Adaptor with Viton O-Ring, Stainless Steel, DN 10/16 KF
What is this article?
Centering Ring Adaptor with Viton O-Ring, Stainless Steel, 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.
