Description
Blank-off flange, fixed, stainless steel, DN 63 CF is a fixed sealing component for ConFlat vacuum ports, used to close unused openings on laboratory and process vacuum apparatus. Made of stainless steel, it matches DN 63 CF flange geometry so that open CF faces can be blanked without intermediate adapters when the mating standard is already CF. Fixed blank-off flanges of this kind are fitted where a durable metal-sealed closure is required to preserve vacuum integrity on manifolds, chambers, and instrument lines. The part is supplied as one piece and serves as an accessory or spare for laboratory equipment vacuum systems. This stainless steel blank-off flange from manufacturer WELCH supports reliable port blanking on DN 63 CF assemblies during setup, reconfiguration, or temporary decommissioning of unused connections. Technicians and system builders can install it on compatible CF hardware to seal open flange faces while retaining the option to remove the blank later and restore the port. It is suited to vacuum manifolds, pump interfaces, and analytical instrument setups that employ ConFlat connections and need a straightforward mechanical seal for spare or idle DN 63 CF ports.

Questions about Blank-Off Flange, Fixed, Stainless Steel, DN 63 CF
What is this article?
Blank-Off Flange, Fixed, Stainless Steel, DN 63 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.
