Description
Silicone O-rings DN 120 are circular elastomer seals sized for DN 120 flat flange connections in laboratory and technical apparatus. Made from silicone, these O-rings serve as plan flange seals that create a defined interface between mating flange faces on glass or process equipment. Each piece has a net weight of 0,007 kg and is supplied as a single unit, allowing straightforward replacement or assembly of individual joints. The DN 120 nominal diameter matches corresponding flange standards used in modular laboratory glassware and related systems. In everyday laboratory work they support reliable sealing of plan flange assemblies during setup, transfer or maintenance operations. These silicone O-rings from manufacturer Witeg form part of the standard sealing accessories employed with DN-rated flat flanges. Their simple geometry permits quick installation without special tools, while the silicone material provides the flexibility expected of elastomer flange seals. Laboratories handling chemical, analytical or process glassware rely on such standardised DN 120 silicone O-rings to maintain consistent joint integrity across experimental and production configurations that use plan flange connections.

Questions about O-rings, DN 120, made of Silicone
What is this article?
O-rings, DN 120, made of Silicone is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Other lab tools & accessories, inside Tools & accessories, in Labware.
This shelf is the bench tools that do not belong to a narrower rack: odd holders, small aids, pieces that complete a setup. The useful check is what the tool touches, and whether that contact adds a contaminant.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
