Description
Blank-off flange, fixed, stainless steel, DN 200 CF is a vacuum-system accessory component intended for sealing unused ports on CF flange connections in laboratory and technical vacuum setups. The fixed blank-off design provides a rigid, non-rotatable closure matched to the DN 200 CF nominal size, supporting clean, metal-sealed interfaces typical of ConFlat-style flange systems. Constructed in stainless steel, the flange is suited to demanding laboratory environments where mechanical stability and compatibility with high-vacuum hardware are required. Supplied as a single piece, it serves as a practical spare or configuration part for vacuum manifolds, chambers, and pump lines. This blank-off flange from manufacturer WELCH belongs to the accessory and spare-parts range for laboratory equipment and is specified for DN 200 CF geometry. It enables straightforward blanking of open CF ports during system build-up, maintenance, or reconfiguration without altering the fixed flange orientation. The component integrates into standard CF vacuum assemblies used across analytical, process, and research laboratories that rely on robust stainless-steel flange hardware for reliable sealing of unused openings.

Questions about Blank-Off Flange, Fixed, Stainless Steel, DN 200 CF
What is this article?
Blank-Off Flange, Fixed, Stainless Steel, DN 200 CF 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.
