Description
Silicone seals for GL thread without PTFE collar provide dependable sealing and tube-fixing performance in laboratory screw-connection systems. Designed for GL 45 threads with an inner diameter of 26 mm, the seal fits PBT screw-connection closures and is intended for securing tubes while ensuring a tight seal. Manufactured from silicone, the component offers the flexibility and chemical resistance typical of this elastomer for everyday laboratory use. The absence of a PTFE collar keeps the design simple and suitable for applications where direct silicone contact is preferred. These seals from manufacturer Duran/DWK Life Sciences carry the DURAN® trademark and are supplied as single pieces. Typical uses include fixing of tubes and general sealing tasks on GL 45 ports. The 26 mm inner opening accommodates corresponding tubing diameters, supporting stable mechanical retention and leak prevention. Net weight is 0,006 kg. Ideal for assembly of laboratory apparatus that relies on PBT screw caps, the seal contributes to reliable fluid-handling set-ups in research, quality-control and preparative work. Its straightforward geometry allows quick installation and replacement during routine maintenance of glassware and tubing systems.

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.
