Description
Silicone seal for GL 32 thread without PTFE collar is a laboratory sealing component featuring an inner diameter of 20 mm, intended for use with PBT screw connection closures. This silicone gasket is suitable for fixing tubes and delivering reliable sealing performance in standard laboratory connection systems. It matches GL 32 threaded PBT caps and provides a practical interface for tubing retention without an added PTFE collar. Supplied by manufacturer Duran/DWK Life Sciences as part of the DURAN® range, the seal supports everyday fluid-handling and apparatus assembly tasks where a flexible silicone seal is required. The single-piece unit weighs 0,004 kg net and fits readily into glassware setups that employ GL 32 threads. Its material properties allow secure yet adaptable contact with tubes and closures, helping maintain leak-resistant connections during routine laboratory work. The 20 mm inner diameter accommodates corresponding tube sizes while preserving a firm seal against the threaded cap. Applications centre on tube fixation and general sealing duties in chemical, analytical or research environments that benefit from a straightforward, collar-free silicone design for GL-threaded 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.
