The ONLY time we used PVC for air mains at work was with Schedule 160,  rated 
for air service. And even at that, we eventually replaced it with SS  tubing 
and welds, due to the low temperature resistance of the PVC. Go above  100F, 
and things degrade RAPIDLY. We had glued fittings blow apart.  Egads...

In my  post that has not made it to digest form yet, I clearly state that 
no  manufacturer of PVC pipe ( on the websites I have visited) recomends 
its  use on compressed air. In fact the sites I visited expressly say it 
is NOT  to be used for compressed air.  And this is for schedule 40 , 80 
and  CPVC. Do some research. Find any manufacturer that does not warn of 
its  dangers and get back to us.  Do not recomend processes that can 
cause  bodily injury without giving warnings. Old car repair is 
inherently  dangerous, but one should not add to that danger needlessly.
