Description
BOLA double-sided seals for GL 25 threads feature a silicone ring with a double-sided PTFE cuff, ensuring that the medium contacts only PTFE during application. Outer diameter is 22 mm, inner diameter 8,0 mm and height 6,6 mm, intended for tube diameters from 7,5 mm to 9,0 mm. This geometry suits GL 25 laboratory connections that need an elastic core with chemically inert sealing faces on both sides. The pack contains 5 pieces, each with a net weight of 0,0028 kg, for convenient stock of standard laboratory sealing components. Polytetrafluoroethylene (PTFE) at the wetted surfaces supports use with aggressive or sensitive media where silicone alone would be unsuitable. From manufacturer Bohlender, the seals follow established BOLA dimensions for GL fittings and tubing ranges, simplifying replacement and system assembly. They are appropriate for stoppers, joints and tubing interfaces in laboratory material setups that require reliable double-sided PTFE contact without changing the GL 25 thread standard.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about BOLA Double-sided gaskets, GL 25, Ø 22 x 8 mm SILICONE-ring with double-sided PT
What is this article?
BOLA Double-sided gaskets, GL 25, Ø 22 x 8 mm SILICONE-ring with double-sided PT is the article on this page. Luminix Health distributes Bohlender 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.
