Description
Silicone sealing ring, VMQ, with vulcanised PTFE cuff is a laboratory sealing component intended for GL 32 screw connection pieces. Constructed from silicone elastomer (VMQ), it provides dependable sealing when used with the corresponding threaded connector. One side is equipped with a vulcanised PTFE cuff that imparts a degree of chemical inertness to the contact surface. The ring has an inner diameter of 10 mm and an outer diameter of 29 mm, accommodating tubes whose internal diameter ranges from 9,0 mm to 11,0 mm. A central bore enables the insertion of glass rods, olives, flexible tubing and similar laboratory accessories without compromising the seal. Typical applications comprise sealing and secure fixation of tubes in chemical and life-science apparatus. This component from manufacturer Duran/DWK Life Sciences is supplied as a single piece and supports stable glassware and tubing assemblies that require both elasticity and surface inertness. The silicone matrix together with the PTFE layer ensures reliable sealing performance under standard laboratory conditions.
This article is part of Lids & seals, in Stoppers, caps & closures.

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.
