Description
BOLA screw-in connecting piece GL 32 with G 1" male thread is a straight polytetrafluoroethylene (PTFE) fitting for larger laboratory and process connections. It unites a G 1" screw-in thread with a GL 32 laboratory thread and offers an 18,0 mm through-bore for generous media flow. The hexagonal body section measures 34 mm across flats, allowing firm wrench engagement during mounting on vessels, manifolds or apparatus. Entirely PTFE construction delivers universal chemical resistance, ensuring the process fluid contacts only this inert polymer and avoiding metallic contamination. Such connectors are used to join tubing, screw-cap systems and G-thread ports when aggressive solvents, acids or bases must be transferred safely. The straight design from manufacturer Bohlender keeps line layouts simple and compact while remaining compatible with standard GL laboratory glassware and plasticware. Supplied as one piece with a net weight of 0,0848 kg, the fitting supports modular, chemically inert fluid paths in research, pilot-plant and industrial laboratory settings that require robust PTFE screw-in adapters for reliable long-term service.

Questions about BOLA GL-Screw-in Tube Fittings, GL 32, Ø 18 mm, G 1'' Opening of the spanner
What is this article?
BOLA GL-Screw-in Tube Fittings, GL 32, Ø 18 mm, G 1'' Opening of the spanner is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
