He also sold all types autobody shop equipment & supplies . He set me up as air compressor installer & maintenance plus occassionaly if the customer wanted to do his own installation , my job was to go to that particular body shop or garge to give the guy instructions & ideas for piping & safety. All compressor companies we dealt with at that time demanded 3/4" Galvanized pipe & fittings , with an inline drain valve for draining water buildup . Black pipe is for gas & is dangerous for compressed air usage . If other than Galv pipe was installed , the company voided the warranty on the compressor . HTH ! God bless, Ken [Reply]   [No Email]

Have to keep and eye on it and have filters if painting. I had 3/4 copper in the last shop, liked it alot. New shop hasn't been hard plumbed yet. Planning on either transport air line (pex) or conventional pex with a starter piece of copper for cooling. [Reply]  [No Email]

Black pipe with malable fittings is fine for air line. My Quincy compresser is factory piped to the tank with black pipe. [Reply]  [No Email]
