Description
BOLA one-sided seals for GL 25 threads combine a silicone ring with a PTFE cuff to provide dependable laboratory sealing. Outer diameter is 22 mm, inner diameter 8,0 mm and height 6,5 mm; they suit tube diameters from 7,5 mm to 9,0 mm. In use the process medium contacts only the PTFE surface, giving chemical resistance while the silicone element supplies elasticity and sealing force. These components from manufacturer Bohlender are packed in units of 10 pieces; differing order quantities are rounded up in steps of ten. Each seal has a net weight of 0,0025 kg, with the media-facing cuff made of polytetrafluoroethylene (PTFE). The design supports secure connections on GL 25 glassware and tubing assemblies where an inert contact surface is required. They are suited to routine laboratory work with aggressive or sensitive media that must not interact with elastomers except through the PTFE barrier, helping maintain clean, chemically compatible seals on threaded fittings.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about BOLA One-Sided Gaskets, GL 25, Ø 22 x 8 mm SILICON O-ring with PTFE washer
What is this article?
BOLA One-Sided Gaskets, GL 25, Ø 22 x 8 mm SILICON O-ring with PTFE washer 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.
