Description
Silicone sealing ring, VMQ, with vulcanised PTFE cuff is a laboratory sealing component designed for GL 45 screw connectors. Constructed from silicone (VMQ) with a vulcanised PTFE cuff on one side, it delivers good sealing performance together with a degree of chemical inertness from the PTFE surface. The integrated bore accommodates glass rods, olives, tubing and comparable inserts for pipes with inner diameters of 25,0 - 27,0 mm. With an inner diameter of 26 mm and an outer diameter of 42 mm, the ring provides firm pipe fixation and reliable sealing in laboratory configurations. Offered as a single piece from manufacturer Duran/DWK Life Sciences, it serves applications focused on sealing and securing tubes within scientific glassware systems. The combination of resilient silicone and the PTFE layer makes it suitable for environments that benefit from both flexibility and reduced interaction with process media. Geometry is matched to standard screw connection pieces, enabling simple incorporation into existing laboratory tubing and glassware assemblies.

Questions about Silicone Sealing Ring, VMQ, with bonded PTFE face
What is this article?
Silicone Sealing Ring, VMQ, with bonded PTFE face 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.
