Description
Silicone seals for GL thread without PTFE collar deliver reliable sealing and tube-retention capability for laboratory screw-connection assemblies. Specified for GL 45 threads with an inner diameter of 32 mm, the seal is compatible with PBT screw-connection closures and is used for fixing tubes as well as providing an effective seal. The silicone construction supplies the elasticity and chemical resistance expected for standard laboratory service. Omitting the PTFE collar results in a simple, direct-contact design suited to applications that do not require an additional fluoropolymer interface. These seals from manufacturer Duran/DWK Life Sciences are marked with the DURAN® trademark and are offered as individual pieces. Primary applications comprise tube fixation and sealing on GL 45 ports. The 32 mm inner diameter matches larger tubing sizes, ensuring secure mechanical hold and leak-tight performance. Net weight is 0,005 kg. The component supports the construction of laboratory apparatus based on PBT screw caps and is well suited to research, analytical and preparative environments. Easy to fit and replace, it facilitates efficient maintenance of glassware and tubing circuits that rely on GL-threaded closures.
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.
