Description
Sealing ring for unground spherical joints S 19 (silicone + FEP) is a specialised laboratory component for schliffless DURAN® spherical joints that achieve sealing exclusively through the dedicated ring. This FEP-coated silicone ring is selected when high chemical resistance of the seal is required. The silicone core combined with the FEP sheath provides the material properties needed for demanding chemical work where conventional seals may be inadequate. Supplied as a single piece with a net weight of 0,001 kg and gross weight of 0,001 kg, the ring ensures reliable closure of unground ball joints in glass apparatus. From manufacturer Duran/DWK Life Sciences, it supports leak-free connections in laboratory setups handling aggressive media without reliance on ground glass surfaces. Its primary application is the effective sealing of schliffless spherical joints, contributing to safe handling of substances in research, synthesis and analytical workflows that benefit from the inert FEP surface and flexible silicone body.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about Sealing ring , for polished sperical joints (silicone + FEP)
What is this article?
Sealing ring , for polished sperical joints (silicone + FEP) 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.
