Description
Silicone seal for GL 32 thread without PTFE collar is a laboratory sealing component with an inner diameter of 16 mm, intended for secure tube fixation and reliable sealing. Manufactured from silicone, it is designed to fit screw connection closures made of PBT and supports applications such as fixing tubes and creating effective seals in laboratory glassware systems. The seal is supplied as a single piece with a net weight of 0,004 kg and is non-sterile for standard laboratory use. This DURAN® accessory from manufacturer Duran/DWK Life Sciences provides a flexible, durable interface for GL 32 threaded connections where direct silicone contact is preferred. By omitting the PTFE collar, the design enables straightforward assembly while maintaining a tight fit around tubing. Suitable for everyday research and analytical setups, the component helps secure tubes and prevent leakage in apparatus that rely on PBT screw caps. Its compact dimensions and precise inner diameter make it a practical choice for maintaining stable connections in general laboratory workflows.

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.
