Description
BOLA screw coupling reducers GL 25 to GL 14 are laboratory fittings for joining two GL-threaded connections of different sizes. Each reducer consists of two screw caps made of PPS with GL threads, a PTFE/FKM seal and a PTFE connecting piece, so the process medium comes into contact only with PTFE. The sealing-lip-to-sealing-lip length is 27,5 mm and the net weight is 0,017 kg, giving a compact transition between GL 25 and GL 14. PTFE wetted surfaces support chemically demanding laboratory fluid paths where an inert interface is required. The PPS screw caps provide the mechanical closure on the GL threads while the PTFE body and seal maintain media isolation. Supplied as one piece, the reducer is intended for glassware and tubing assemblies that must bridge unequal GL sizes without introducing additional contact materials. These BOLA components from manufacturer Bohlender are used in analytical, synthesis and general laboratory setups that need a reliable size reduction between GL 25 and GL 14 threads with PTFE-only media contact throughout the connection.

Questions about BOLA Reducing Screw Thread Adaptor Couplings, GL 25 - GL 14 PTFE, PPS nuts
What is this article?
BOLA Reducing Screw Thread Adaptor Couplings, GL 25 - GL 14 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.
