Description
BOLA screw-in connectors GL, NPT 1/4" – GL 18, featuring two male threads and AF 15, serve as dedicated laboratory fittings for screwing into BOLA reactor-lid ports and forming a GL threaded nozzle. The combination of an NPT 1/4" screw-in thread and a GL 18 threaded nozzle creates a practical link between reactor-lid connections and larger GL-compatible laboratory components. A hexagonal gripping surface with the standard wrench size of 15 mm allows firm, controlled mounting using common laboratory spanners. Offered by manufacturer Bohlender, these connectors support modular reactor builds and everyday laboratory process work where NPT-to-GL transitions must remain compact and mechanically clear. Each unit is supplied as one piece with a net weight of 0,0101 kg, fitting neatly into BOLA reactor-lid layouts. The dual external-thread arrangement keeps the connection path short and organised for fluid or gas lines attached to the lid. Laboratories that rely on BOLA reactor accessories can use this fitting to standardise GL 18 attachments while retaining the NPT 1/4" interface on the reactor side, simplifying assembly of multi-port lid systems.

Questions about BOLA Screw In Fittings GL, NPT 1/4'' - GL 18 2x male thread, SW 15
What is this article?
BOLA Screw In Fittings GL, NPT 1/4'' - GL 18 2x male thread, SW 15 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.
