All my air lines are brass pipe. There is about 120' of brass lines. Note always pull off the top of the air line for your air needs and add drip legs at the end of the run. The line needs to run at a 1/4" per foot of fall from the compressor. This will move the water to the drip leg at the end of the run. Use copper pipe. Good Luck

I can explain it to you but I can't help you understand it.
