PVC Pipe for air lines?

Not unless you want to kill yourself. They aren't made for air pressure, only liquid and not the type of pressures that you see in a compressed air system. Check garagejournal.com for extensive discussions on this very subject. Only use black pipe, heavy wall copper pipe or pex rated for air, rated at 300 PSI burst pressure. Some will say yes, but your wife is worth more than a few dollars for cheap air lines.

Thanks for the info. I'm gonna guess that "wife" was a typo.

Yeah, sent it from my phone. stupid autocorrect . Meant to type life.
Although if married, maybe the wife would appreciate the thought.

When PVC fails (and it will under air pressure) it is a catastrophic failure. Little shards everywhere. The stuff is bad news. Guys will say they've never had a problem, but it is just a matter of time.

Look into the aluminum tube type systems that are popular now. The tube is coated with blue epoxy, makes it real pretty.

Next choice would be sweated copper lines.

Last choice is black iron pipe. You'll never get it to seal 100% so it is problematic.

There is also a system available that uses nylon tubing to connect from fitting to fitting, but I don't have any experience with it.
