I've had 3/4" PVC air lines in my garage & basement (9 outlets total)

The
pipe's rated at 400 PSI and went together a lot easier than iron

So far, no problems.

that it will kill you.


For vibration resistance, have your pipe make a turn before clamping
it to
anything - this gives it wiggle room.

here's one example of possible problems:
