Hydraulic Accumulator Nitrogen Charging Kit - 7-in-1 Pressure Test Tool with 40MPA FPU-1-25 Gas Valve for Hydraulic Systems | Perfect for Industrial Maintenance, Construction Equipment & Heavy Machinery Testing

This is a good kit, BUT the hose that is in the kit does not fit any Nitrogen tank. The fitting on the hose is not marked with a number indicating what it is. After going to my local PraxAir place we have determined that the end on the hose is a CGA-540/oxygen fitting. Of coarse putting oxygen into an accumulator is a no no so I find it interesting that the hose that comes with the Nitrogen charging kit fits an oxygen tank and not a nitrogen tank. So you will need a CGA-540 to CGA-580 adaptor to use with 1800-2200psi nitrogen tank. ADDED INFO. I received a response from the seller. The Fitting on the end of the hose is an international standard G5/8. Get the adaptor mentioned above and all is well.
