Description
BOLA Thread Adapter GL, GL 18 / GL 25 Ø 10,5 mm PTFE, 2 x external thread is a straight thread transition piece for laboratory connection and fluid-handling systems. Produced entirely from PTFE, it offers two external GL threads that join a GL 18 fitting to a GL 25 fitting in a straight geometry. The medium comes into contact solely with PTFE, providing universal chemical resistance for standard laboratory media. Dimensions specify conversion from external thread GL 18 to external thread GL 25, with a diameter of 10,5 mm. Delivered as one piece with a net weight of 0,022 kg, the adapter from manufacturer Bohlender is intended for laboratory material setups that require inert polymer links between different GL sizes. The straight design eases installation in glassware trains, tubing assemblies and compact apparatus where space and chemical compatibility both matter. Because the wetted surface remains PTFE only, the component supports clean, chemically robust transitions in analytical and preparative environments. It is suitable wherever reliable GL screw-thread adapters made of high-performance polymer are needed for everyday laboratory work.

Questions about BOLA Thread Adaptor GL, GL 18 / GL 25 Ø 10,5 mm PTFE, 2 x Male Thread
What is this article?
BOLA Thread Adaptor GL, GL 18 / GL 25 Ø 10,5 mm PTFE, 2 x Male Thread 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.
