hi,as other guys here have said,only run steel pipe for your air lines. BUT put a large U bend in the pipe(using 90 % elbows(4 of them) make the bend at least 2 feet long,and put a garden hose bib in the center of the bend (at bottom) that way the water will collect there (condensation) and you can drain it using the hose bib. im boatbob2
