Description
BOLA Replacement Special Seals, Ø 10 mm PTFE/FKM are easily exchangeable sealing elements that combine a PTFE seal with an FKM O-ring for use in PTFE guide sleeves. The special seal is intended to provide reliable sealing against the stirring shaft in laboratory stirring closures. Designed for a shaft diameter of 10 mm and a cap thread of GL 25, these components support controlled, repeatable assembly where shaft sealing is required. The seal body is based on polytetrafluoroethylene (PTFE), a material widely used in chemical laboratory environments for its chemical resistance and low friction characteristics when contacting rotating shafts. Supplied as a pack of 10 pc(s) with a net weight of 0,001 kg, the set is suited to routine maintenance and spare-part stocking for stirring apparatus. These BOLA seals from manufacturer Bohlender fit the corresponding PTFE guide-sleeve systems and allow straightforward replacement without complex tools. They are relevant for Rührverschlüsse and related stirring-closure assemblies where PTFE/FKM special seals must match defined shaft and GL thread dimensions.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about BOLA Special Gaskets, Ø 10 mm PTFE/FKM
What is this article?
BOLA Special Gaskets, Ø 10 mm PTFE/FKM 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.
