Description
BOLA screw couplings GL 45 PTFE with PPS screw caps are laboratory connectors designed to join two GL threads of the same size in a chemically resistant assembly. Each unit comprises two screw caps made of PPS, rated up to +200 °C, fitted with a PTFE/FKM seal and a connecting piece of pure PTFE. The process medium contacts only PTFE, supporting clean, inert fluid paths in glassware and apparatus setups. The sealing-lip-to-sealing-lip length is 23 mm for the GL 45 thread size, giving a compact coupling profile suited to bench and apparatus work. Net weight is 0,125 kg per piece, supplied as a single unit. Material construction centres on polytetrafluoroethylene (PTFE) for the wetted path, while the PPS caps provide mechanical strength and thermal stability under typical laboratory conditions. These couplings from manufacturer Bohlender are intended for connecting matching GL threads where chemical inertness and reliable sealing are required. Ideal for laboratory fluid handling, glassware interconnection and apparatus assembly where GL 45 interfaces must be joined without exposing the medium to non-PTFE surfaces.

Questions about BOLA Threaded Couplings, GL 45 PTFE, PPS nuts
What is this article?
BOLA Threaded Couplings, GL 45 PTFE, PPS 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.
