Price of copper tubing!

bet it be a lot cheaper and air be cleaner if you used nylon hose like used on commercial truck air brake systems and handle pressures up to 150 lbs easy!
So it might do a high PSI (still less than a 2 stage compressor at 175psi) but what’s the diameter of those lines? Pretty small right? Bigger the pipe the better the flow, just like exhaust headers and everything else we try to go big on our cars.
