Description
Centering Ring Adaptor with Perbunan O-Ring, stainless steel, DN 32/40 KF is a vacuum flange accessory for laboratory and process equipment. It is intended for KF (small-flange) connections in the DN 32/40 size range, where a centering ring and elastomeric seal are required to align and close the joint between mating flanges. The stainless-steel body provides a robust metal interface, while the integrated Perbunan O-ring forms the sealing element for typical laboratory vacuum service. Supplied as a single piece from manufacturer WELCH, this adaptor fits the common accessory and spare-parts role around pumps, manifolds, and analytical apparatus that use quick-release KF fittings. The DN 32/40 KF format supports flexible assembly when components of those nominal sizes must be coupled. Clear geometry and a defined seal make routine installation and replacement straightforward in daily lab workflows. Use it wherever a stainless centering ring with Perbunan sealing is specified for KF vacuum lines.

Questions about Centering Ring Adaptor with Perbunan O-Ring, Stainless Steel, DN 32/40 KF
What is this article?
Centering Ring Adaptor with Perbunan O-Ring, Stainless Steel, DN 32/40 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.
