BOLA GL reducers GL 45 – GL 18 PTFE/PPS provide a practical laboratory adapter from larger GL vessel threads to a GL 18 nozzle for tubing and accessories. Each reducer features a black PPS screw cap and a movable PTFE reducing nozzle with an FKM O-ring, enabling a secure step from a GL 45 thread cap to a GL 18 threaded outlet. The movable reducing nozzle allows the vessel to be exchanged without first disconnecting attached equipment, preventing twisting of hoses and cables. Only PTFE comes into contact with the medium, supporting chemically demanding applications. Suitable for hose diameters from 1,6 mm to 10,0 mm, the fitting accommodates common laboratory tubing sizes. It is offered as one piece with a net weight of 0,052 kg and uses polytetrafluoroethylene for the wetted reducing element. These BOLA GL reducers from manufacturer Bohlender are well suited to research and process laboratories needing inert media contact, dependable GL-thread reduction, and straightforward vessel handling in everyday fluid systems.

Questions about BOLA GL-Reductions, GL 45 - GL 18 PTFE/PPS
What is this article?
BOLA GL-Reductions, GL 45 - GL 18 PTFE/PPS 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 Labmateriaal.
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.
