Re: How much air PSI can a standard propane bottle safely hold????

I am in the propane business and yes the propane pressure is far greater than what your compressor will produce, that being said I have people pick up old tanks that we can not fill for one reason or another mostly old valve regulations and they will grab them and change the valve and use that for an air tank. I do not feel comfortable myself doing that just because it is not what it was made for but it does work. The real chance for a problem is the propane vapor in a tank and static electricity that can be caused during the purging of the propane vapor from a tank, propane vapor is heavier than air so open the tank urn up side down and leave it for a few days and if you are a chicken like myself get a little nitrogen purge the tank and off you go. Sorry to be so long winded.
