Description
BOLA replacement inner parts for GL 25 fittings with 6,0 mm hose outer diameter are spare sealing components for laboratory tubing connections. Each set consists of a clamping ring together with a sealing wedge and sealing plate made of PTFE, so that the flow medium contacts only PTFE and benefits from very good chemical resistance. An additional FKM O-ring is specified for fittings intended for hose outer diameters below 3 mm and remains out of contact with the medium. These parts restore the function of existing BOLA screw fittings without replacing the complete assembly and are suited to routine maintenance of fluid-handling lines in chemical and analytical laboratories. Supplied from manufacturer Bohlender as a pack of 2 pieces with a net weight of 0,011 kg, they match GL 25 thread geometry and the stated 6,0 mm hose outer diameter for a precise fit. PTFE wetted surfaces support use with aggressive media while the compact spare-part format keeps laboratory stocks lean and ready for quick exchange during setup or service work.

Questions about BOLA Replacement Inner Parts, GL 25 aØ 6 mm PTFE, PVDF
What is this article?
BOLA Replacement Inner Parts, GL 25 aØ 6 mm PTFE, PVDF 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.
