Description
O-ring in silicone (VMQ) for desiccators, DN 250 (290 x 5,3 mm), provides a flexible sealing element sized to the nominal diameter of compatible laboratory desiccators. Manufactured from silicone elastomer, the ring delivers the elasticity and durability needed for repeated sealing cycles while forming a reliable barrier against ambient moisture. The stated dimensions of 290 x 5,3 mm ensure correct seating on matching desiccator flanges, supporting grease-free closure where appropriate. This single-piece component from manufacturer Duran/DWK Life Sciences is intended for routine laboratory use in drying and storage applications that require a consistent airtight fit. Its silicone construction offers good chemical resistance under standard laboratory conditions, making it a practical spare or replacement part for desiccator maintenance. Suitable for laboratories seeking a straightforward sealing solution matched to DN 250 equipment.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about O-RING,silicone rubber, suitable for desiccators, DN 250 (290 x 5,3 mm)
What is this article?
O-RING,silicone rubber, suitable for desiccators, DN 250 (290 x 5,3 mm) 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.
