Description
Silicone seal for GL thread without PTFE collar is a laboratory sealing element intended for GL 25 screw connections. The seal has an inner diameter of 8 mm and is manufactured from silicone, providing a flexible gasket surface for tube fixation and sealing duties. It is designed to fit PBT screw connection closures and is typically used to secure and seal tubes or rods passing through GL 25 ports. Typical applications include fixing of tubes and creating a reliable seal at the threaded interface in laboratory glassware and apparatus assemblies. The component carries the DURAN® registered trademark and is supplied as a single piece with a net weight of 0,002 kg. From manufacturer Duran/DWK Life Sciences, this silicone seal supports clean, reusable sealing around tubing in chemical, analytical and life-science workflows where a GL 25 thread is present. Absence of a PTFE collar keeps the design simple and focused on silicone-to-thread contact, making it a practical spare or replacement part for screw-cap connection systems used on bottles, reactors and laboratory vessels.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about Silicone Sealing Ring , for GL threads, without PTFE washer
What is this article?
Silicone Sealing Ring , for GL threads, without PTFE washer 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.
