Leak testing with shop air
Posted: Thu Jul 27, 2017 10:52 am
Its an empty R12 system with Mineral Oil and UVDye installed - but I don't have access to Nitrogen - so I'd like to be able to pressurize with normal shop air. I know air 's got moisture in it but I have another Accumulator that I can put on (and ruin) in the process of leak testing. I can put the new Accumulator back on after I find the leak ...
are there any other good reasons not to use compressor air in this situation?
Also, can I add R134 and pressurize it with the shop air.
thanks
