Description
BOLA Replacement Screw Cone Caps HT with GL 18 thread are black laboratory screw caps for hose outer diameters from 0,8 to 10,0 mm. Manufactured from PPS reinforced with glass fibre, each cap features a grippy knurled rim and a hexagonal profile (SW 22) that support firm seating and easy opening or closing on GL-threaded fittings. These replacement screw cone caps from manufacturer Bohlender offer good chemical resistance and remain suitable for temperatures from –20 °C to a maximum of +250 °C. The reinforced polymer construction is intended for laboratory tubing connections that require a robust spare cap after wear or routine service. Supplied as a single piece with a net weight of 0,013 kg, the GL 18 HT variant covers a wide hose outer-diameter window for flexible fluid lines. Knurling improves grip during manual work, while the hexagon allows controlled torque with standard tools, making the cap a practical spare for BOLA screw cone systems in research and technical laboratories.

Questions about BOLA HT Replacement Caps, GL 18, Ø 0,8 - 10 mm Glass-fibre reinforced PPS cap ma
What is this article?
BOLA HT Replacement Caps, GL 18, Ø 0,8 - 10 mm Glass-fibre reinforced PPS cap ma is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
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.
