Most shops I have seen use iron pipe for air, but I was just looking at a
couple on-line specs sheets on PVC and it looks like if I were to
distribute air at 125 PSI in my shop using 1" Schedule 40 PVC I would have
about a 30% safety margin at the worst case scenario. That's based on
120F operating temperature. While yes it does hit 120F here in the desert
once in a great while I don't think its ever gotten above 105 in the shop
building. Better safe than sorry though.

Wadda ya think?

P.S. I have seen other shops use PVC also, and they said they never had
any problems.

The only real issue I see is that "wish this hose was 2 inches longer"
factor. I could probably mitigate that by using brass fittings at the
ends and securing them properly at the wall, and of course the fact that
there would be air all over the shop instead of in one corner would help
quite a lot.


I started with PVC years ago, and never had any problem, but that doesn't me
you won't. Most building or mechanical codes forbid it because of the
possible air born chards due to impact damage.

When I added to my shop a couple of years ago, I switched to PEX. I found
that PEX will not shatter even when frozen, and can even be easier to route.
The only down side is the cost of the tool.
