Description
BOLA screw couplings GL 14 PTFE with PBTP screw caps provide a compact laboratory connection for joining two GL threads of equal size. The assembly uses screw caps of PBTP, suitable up to +180 °C, combined with a PTFE/FKM seal and a PTFE connecting piece so that the medium contacts only PTFE. This wetted-path design supports chemically inert fluid transfer between matching GL glassware or apparatus ports. For the GL 14 thread, the length from sealing lip to sealing lip is 15 mm, yielding a short, space-efficient coupling. Net weight is 0,01 kg, and the product is supplied as one piece. Construction is based on polytetrafluoroethylene (PTFE) for the media-contacting components, with PBTP caps delivering mechanical hold and thermal performance for routine laboratory use. Offered by manufacturer Bohlender, these couplings are intended for secure GL-to-GL joints where chemical resistance and a defined seal geometry matter. Suitable for laboratory glassware interconnection, small-scale fluid handling and apparatus setups requiring a GL 14 PTFE coupling with PBTP screw caps.

Questions about BOLA Threaded Couplings, GL 14 PTFE, PBTP nuts
What is this article?
BOLA Threaded Couplings, GL 14 PTFE, PBTP nuts 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.
