Description
BOLA swivel screw fittings for GL 18 necks hold sensors, tubes or hoses with an outer diameter of 6,0 mm and permit a maximum deflection angle of 5°. The screw cap is made of PPS and the inner parts of polytetrafluoroethylene (PTFE), giving a chemically resistant interface for laboratory probe and tubing connections. The sensor, tube or hose is first passed through the fitting; the assembly is then screwed onto the GL socket and the inserted element is locked in the required position. This arrangement from manufacturer Bohlender enables controlled angular positioning of probes and lines on glassware or apparatus fitted with GL 18 threads. With a net weight of 0,0196 kg and supplied as one piece, the compact fitting suits analytical setups, process monitoring and general laboratory installations where slight angular adjustment of the inserted element is needed. PTFE contact surfaces support inert handling of many reagents, while the PPS cap provides mechanical stability for repeated assembly on GL-threaded ports used for temperature sensors, sampling lines or transfer tubing.

Questions about BOLA Swivelling screw fitting, GL 18, a Ø 6,0 mm, max. 5° PPS cap, inner parts m
What is this article?
BOLA Swivelling screw fitting, GL 18, a Ø 6,0 mm, max. 5° PPS cap, inner parts m 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.
