Description
Sealing ring for unground spherical joints (VITON) is a fluoroelastomer (FKM) component designed for S 29 unground spherical joints that achieve a seal solely through the elastomer ring. These VITON rings are intended for vacuum applications where elevated chemical resistance is essential. Material properties of the fluoroelastomer support reliable performance when aggressive media or demanding laboratory conditions are present. Supplied as a single piece with a net weight of 0,002 kg, the ring from manufacturer Duran/DWK Life Sciences provides effective sealing of unground spherical joints in glassware assemblies. Its construction ensures a consistent vacuum-tight interface without reliance on ground joint surfaces. The component is suited to research and analytical setups that require durable chemical resistance together with dependable vacuum integrity. Application centres on the secure sealing of schlifflose Kugelschliffe systems, delivering a practical solution for laboratory vacuum work where joint geometry depends entirely on the sealing ring.
This article is part of PVC, PTFE & other tubing, in Tubing, hoses & fittings.

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 PVC, PTFE & other tubing, inside Tubing, hoses & fittings, in Labware.
PVC is the flexible everyday tube for water and mild aqueous liquids. PTFE is the stiff, almost inert tube for solvents. Other polymers sit between them. The bore, the wall and the chemical resistance are the specification, and the tube is cut to length.
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.
Which category should I open next?
