Looking to add an air compressor to my garage, not anything big, just a 20 or so gallon for the moment. Not looking to keep it portable though, but stationary in a corner. My question is can I run a stationary line in PEX? I know PVC is a big no as far as compressed air lines, and metal lines are out of the budget. I know they sell Garage-Pak air line kits, but like metal, it's out of the budget. I have a PEX crimping tool, and the tubing is affordable. Would there be any objections to using PEX? Max pressure would be in the 120psi range and not pressurized all the time.
