Description
BOLA double-sided seals for GL 18 threads feature a silicone ring with double-sided PTFE cuffs, ensuring the process medium contacts only PTFE during application. Dimensions are 16 mm outer diameter, 6,0 mm inner diameter and 4,6 mm height, intended for GL 18 threads and tubing diameters from 5,5 to 6,5 mm. The PTFE contact surface supports chemically demanding laboratory sealing tasks where fluoropolymer wetting is preferred. Supplied in packs of 5 pieces with a net weight of 0,01 kg, these seals fit standard laboratory glassware and apparatus connections. Products from manufacturer Bohlender in this BOLA range pair a resilient silicone core with PTFE cuffs for elasticity and media-compatible sealing. They are suited to research, analytical and preparative setups that require reliable GL-thread interfaces and defined tubing ranges. Geometry and material contact follow the stated manufacturer data, simplifying selection against existing GL 18 fittings. Use them where clean PTFE contact and secure sealing at the tube interface are required without changing the specified dimensions or construction.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about BOLA Double-sided gaskets, GL 18, Ø 16 x 6 mm SILICONE-ring with double-sided PT
What is this article?
BOLA Double-sided gaskets, GL 18, Ø 16 x 6 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.
