Description
Hinge clamp ring with closure by ring and nut bolt, DN 32/40 KF is a laboratory flange accessory for joining matching KF components at the DN 32/40 nominal size. The hinged ring opens for placement around aligned flanges and is secured by a ring-and-nut-bolt closure, providing a controlled mechanical joint without welding or permanent fixtures. Supplied as 1 pc, it is suited to assembly, service and spare-part duties on apparatus that specifies KF small-flange interfaces in this diameter range. The DN 32/40 KF designation marks compatibility with the corresponding standardized flange pair, supporting consistent fitment across vacuum and process laboratory installations that use this connection family. From manufacturer WELCH, the clamp ring is positioned as an accessory or replacement part for laboratory equipment rather than a complete instrument. Hinged construction eases installation where flanges are already seated in a line or manifold, and the nut-bolt closure supports repeatable tightening during routine maintenance cycles. Specify this DN 32/40 KF hinge clamp ring wherever a dependable, demountable mechanical fastening of matching KF flanges is needed in research, analytical or technical laboratory environments that follow KF connection practice.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Hinge clamp ring with closure by ring and nut bolt, DN 32/40 KF
What is this article?
Hinge clamp ring with closure by ring and nut bolt, DN 32/40 KF is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
