Description

Silicone seal for GL 25 thread without PTFE collar is a laboratory sealing element with an inner diameter of 10 mm. Fabricated from silicone, it is designed to fit screw connection closures made of PBT and supports reliable tube fixation as well as general sealing tasks. The component is supplied as 1 pc and carries the DURAN ® trademark from manufacturer Duran/DWK Life Sciences. With a net weight of 0,002 kg it remains lightweight yet functional for everyday laboratory assemblies involving GL-threaded joints. Typical use includes securing tubes in place and creating effective seals at connection points where a PTFE collar is not required. The silicone material provides the flexibility needed for repeated assembly while maintaining compatibility with standard PBT closures. This seal integrates readily into glassware and tubing systems that employ GL 25 threads, offering a straightforward solution for fixation and sealing applications in research and analytical settings.

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.
