Having experienced the exploding pvc pipe, I would have to agree that
it is not a good idea. This was at the original Cirrus Design
factory. It was on the order of 2" dia. and I think rated 400psi. It
lasted a year or two before it let go. There was not an air dryer at
the compressor, which meant that there was certainly some oil in the
line, which as mentioned, is not good for pvc. Also, we felt that the
shock of turning tools on and off contributed to the failure. The
reason we felt this is because it blew right when someone let off the
trigger on a sander. Fortunately, the shrapnel didn't go very far and
no one got hurt (except our ears!).
