Description
BOLA replacement special seals for shaft diameter 6 mm are readily interchangeable sealing inserts combining a PTFE seal with an FKM O-ring for PTFE guide sleeves. They provide the sealing interface against the stirring shaft in laboratory stirrer closure systems and restore leak-tight performance when the original seal is worn. Compatible with cap threads GL 18 and GL 25, these seals fit the corresponding BOLA PTFE guide-sleeve assemblies used in chemical mixing and reaction setups. The pack contains 3 pieces and has a net weight of 0,001 kg, making them practical consumables for routine maintenance of stirrer hardware. Material is polytetrafluoroethylene (PTFE) with an FKM O-ring for chemical resistance and reliable shaft contact. From manufacturer Bohlender, the BOLA special seals are intended for straightforward exchange in PTFE guide sleeves without complex tools, supporting continuous laboratory stirring applications in research, synthesis, and analytical environments where consistent shaft sealing is required.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about BOLA Special Gaskets, Ø 6 mm PTFE/FKM
What is this article?
BOLA Special Gaskets, Ø 6 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.
