Description
Blank-off flange in stainless steel with DN 16 KF geometry is designed to close unused ports on vacuum manifolds, pumps and laboratory vacuum lines. The KF small-flange interface matches widely used ISO-KF hardware found on analytical and process equipment, allowing a clean mechanical seal when a branch must be blanked. Stainless steel construction provides durability and chemical resistance under typical laboratory vacuum conditions. This blank-off flange from manufacturer WELCH is supplied as a single-piece accessory for laboratory equipment and supports tidy configuration of vacuum setups during installation, maintenance or system modification. DN 16 is a common size on compact vacuum assemblies, making the part a practical spare for service kits and bench infrastructure. When fitted with a suitable KF centring ring and clamp, the flange helps maintain a consistent seal on idle connections. It is suitable for laboratories operating filtration trains, vacuum ovens, evaporators or dedicated vacuum networks that rely on KF fittings and need reliable port closure without improvised caps.

Questions about Bride d'obturation, acier inoxydable, DN 16 KF
What is this article?
Bride d'obturation, acier inoxydable, DN 16 KF is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Raccords pour tuyaux, adaptateurs & raccords, inside Tubes, tuyaux et raccords, in Matériel de laboratoire.
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.
