I have some air tools I want to test before i sell but no compressor, I have a spare cylinder of pub gas Co2 , can I use this through a regulator to cobble together some kind of air line to test the tools ? The biggest is a grinder which is 7 bar - 100 psig .
use a conector and pipe of a car tire pump and clip it on your car tire it will be sufficient to test or fit a valve on some pipe and take it to the local garage tire pump and try
