Description
Sealing ring in Viton for KS 13/5 is a dedicated sealing element for spherical joint assemblies of joint size KS 13/5. The ring is made of Viton and is designed to sit between the matching spherical joint ball and socket, supporting a reliable seal in grease-free or low-lubricant laboratory connections. It is supplied as one piece with a net weight of 0,001 kg and is classified among joint connection products. This sealing ring from manufacturer Rettberg is offered under the registered trademark Rettberg ®. Viton is selected for its suitability as an elastomeric seal material in laboratory glassware applications where chemical resistance and dimensional fit to the KS 13/5 spherical interface are required. The component is intended for use with corresponding KS 13/5 spherical joint halves, helping to complete flexible glassware linkages in modular apparatus. Laboratories assembling or maintaining spherical joint systems can employ this Viton sealing ring to restore or establish the sealing function at the KS 13/5 size without altering the glass components themselves. It forms a practical spare or accessory part within spherical joint setups used in research and routine laboratory work.
This article is part of PVC, PTFE & other tubing, in Tubing, hoses & fittings.

Questions about Sealing ring, Viton, for size 13/5
What is this article?
Sealing ring, Viton, for size 13/5 is the article on this page. Luminix Health distributes Rettberg 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.
