Description
Sealing ring for unground spherical joints (VITON), size S 41, provides effective sealing for schliffless ball joints used in laboratory glassware systems. Because unground spherical joints achieve tightness exclusively through the sealing ring, the choice of a high-performance elastomer is essential. Produced from fluoroelastomer (FKM/VITON), the ring excels in vacuum applications and situations that demand elevated chemical resistance. Its material characteristics support reliable performance when aggressive substances or reduced-pressure conditions are encountered. Offered as a single piece with a net weight of 0,002 kg from manufacturer Duran/DWK Life Sciences (DURAN®), this sealing ring ensures secure closure of unground spherical joints without ground glass surfaces. It serves as a practical accessory for vacuum lines, reaction setups and other laboratory apparatus requiring durable, chemically resistant joint seals in both research and routine analytical environments.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about Sealing Ring , for polished sperical joints (VITON)
What is this article?
Sealing Ring , for polished sperical joints (VITON) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Lids & seals, inside Stoppers, caps & closures, in Labware.
Lids and seals are the covers of dishes, jars and tanks: a snap lid, a sealing film, a gasket. The seal is doing the work. A lid that only rests on the rim does not contain a volatile liquid.
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.
