Description
Replacement gasket for plastic olive, silicone (VMQ), is a sealing component that prevents or limits unwanted substance transfer from one space to another in laboratory constructions. Made of silicone (VMQ), it is intended as a spare part for achieving a leak-tight connection of plastic olives used with plastic hose couplings. The gasket is designed specifically for plastic olives corresponding to article numbers 29 255 06 03 and 29 247 05 04, supporting secure assembly in tubing and transition systems. Its flexible silicone construction helps maintain seal integrity at the olive interface during routine laboratory fluid handling. Supplied as a single piece with a net weight of 0,001 kg and a gross weight of 0,002 kg, this DURAN® component from manufacturer Duran/DWK Life Sciences serves as a practical replacement element for existing setups. It is suitable for use in transition pieces, ground-joint reducers and screw-coupling arrangements where a reliable silicone seal is required. The gasket forms an integral part of modular laboratory glassware and plastic connection assemblies that demand controlled, drip-free joints without altering the surrounding apparatus.

Questions about Replacement Seal
What is this article?
Replacement Seal is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
