Description
Centering ring with screen and Perbunan O-ring, stainless steel, DN 100 ISO-K is a flange accessory for laboratory and technical vacuum assemblies that use the ISO-K connection standard. The component brings together a stainless steel centering ring, an integrated screen and a Perbunan O-ring so that mating DN 100 ISO-K flanges can be aligned, sealed and protected at the joint. The stainless steel body provides a robust mechanical interface, while the screen element sits in the flow path of the connection and the Perbunan elastomer forms the compressible seal face. Pack size is 1 piece, making the item suitable as a dedicated spare or replacement part during installation or maintenance of DN 100 ISO-K lines. This centering ring from manufacturer WELCH belongs to the accessories and spare-parts range for laboratory equipment and supports routine work on pumps, chambers and process hardware that specify screened ISO-K seals. Use it wherever a DN 100 ISO-K joint requires both centering geometry and a Perbunan O-ring with screen in a single stainless steel unit.

Questions about Centering Ring with Screen and Perbunan O-Ring, Stainless Steel, DN 100 ISO-K
What is this article?
Centering Ring with Screen and Perbunan O-Ring, Stainless Steel, DN 100 ISO-K 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.
