Description
Red FEP-coated O-ring DN 200 is a precision sealing accessory for flat-flange laboratory vessels. It features an elastic silicone core fully and seamlessly enclosed by an FEP jacket, delivering good elasticity together with outstanding chemical resistance. Vessels that use a ring-groove ground joint have a circular recess in the ground face into which a matching gasket fits; this O-ring engages that groove accurately and seals the vessel tightly. Application is the dense closure of flange vessels. The ring is supplied as a single piece, with a net weight of 0,022 kg and a gross weight of 0,043 kg. This red component from manufacturer Duran/DWK Life Sciences is not suitable for desiccators. The FEP outer layer protects the silicone core without interrupting elasticity, supporting dependable performance in chemically aggressive laboratory environments. It is suited to plan-flange glassware and comparable flange assemblies that require a durable, chemically resistant O-ring for secure ring-groove sealing.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about O-Ring, red, FEP coated, not suitable for desiccators
What is this article?
O-Ring, red, FEP coated, not suitable for desiccators 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.
