do NOT use any sort of PVC plastic pipe for the air lines. When
it breaks, it grenades,

There are plastic pipes designed for air use but they only go to 1/2"
which may not be large enough for a big comp. They are reliable though and
the push fittings are quick to install.

There are larger plastic pipes that are rated for air use. They're green
plastic (I think ABS.) The fittings are glued on with a solvent cement. One
brand name is Chem-Air. They are expensive.
