Description
BOLA screw-in connecting pieces are straight PTFE fittings that join a GL 25 thread with an NPT 3/8" screw-in connection. This model offers an 8,0 mm through-bore and a hexagonal wrench size of 27 mm, supporting stable installation in laboratory fluid handling and apparatus assemblies. Made from polytetrafluoroethylene, the fitting ensures the medium contacts only PTFE and therefore provides universal chemical resistance for corrosive reagents and high-purity applications. The straight design facilitates clean integration into tubing circuits, vessel interfaces and modular stands where non-metallic, inert wetted surfaces are required. Each connector is supplied as a single piece with a net weight of 0,042 kg, suited to robust yet chemically inert transfer setups. These BOLA fittings from manufacturer Bohlender deliver reliable screw-in transitions for analytical, preparative and process work. The larger hex profile aids controlled tightening, while the defined bore helps preserve consistent flow paths in chemically demanding laboratory environments that depend on durable PTFE connectors.

What is this article?
BOLA GL-Screw-in Tube Fittings, GL 25, Ø 8 mm, NPT 3/8'' 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.
