Has anyone used PEX tubing to run compressed air in a shop?

I had copper air lines in my old garage and really liked it. I'm getting
tired of tripping over rubber hoses in the new garage. I think one of my
coworkers that I've loaned tools to before has a PEX crimper, so if I can
borrow a crimper is PEX worth the trouble for an easy 25' run? Or should
I just go copper again now that Cu prices are dropping again. (of course
with PEX, maybe I could buy a 100' roll and run a line all the way around
the garage instead of just down one side...)

You need pex-al-pex that can handle air

There is another kind of PEX piping that is used in residential and
commercial applications and in pressure service on compressed air and
compressed gas systems. It is known as crosslinked
polyethylene-aluminum-crosslinked polyethylene (PEX-AL-PEX).
