Description
O-rings DN 60 silicone PTFE-coated are precision sealing elements designed for laboratory glassware and apparatus connections. Each ring combines a resilient silicone core with a continuous PTFE coating, giving the seal the elasticity needed for reliable seating together with the chemical resistance associated with fluoropolymer surfaces. The nominal diameter DN 60 suits corresponding ground-joint, collar and hat-sleeve geometries commonly found in laboratory set-ups. Supplied as a single piece with a net weight of 0,005 kg, the component is ready for immediate installation in vacuum lines, reaction vessels or transfer assemblies where a clean, inert sealing interface is required. These O-rings from manufacturer Witeg belong to the family of sleeve and collar gaskets used to maintain tight joints between glass or metal flanges without introducing metallic contact. The PTFE outer layer helps reduce sticking and simplifies demounting after thermal cycling, while the silicone interior maintains conformability under moderate compression. Ideal for routine laboratory sealing tasks involving flat or conical interfaces of DN 60 size, the rings support reproducible assembly of glass apparatus and process equipment.

Questions about O-rings,made of silicone, PTFE coated DN
What is this article?
O-rings,made of silicone, PTFE coated DN is the article on this page. Luminix Health distributes Witeg 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.
Which category should I open next?
The category is Stoppers, caps & closures. The sub-category is Lids & seals. The catalogue is Labware.
