I just bought a small industrial air compressor and want to put schedule 40 plastic pipe in my shop for air lines around the shop to various places. I know I have seen this done in other shops. Lowe's plastic pipe fittings all have a warning label "Not for compressed air or gas". My pipe is from another supplier and the fittings state "Pressure". Has anyone had any problems using plastic pipe? I will be running a max of 150 lbs pressure. I want to use 3/8" QD air fittings and plan to run the air directly out of the 60 gallon tank without a regulator (since it doesn't have one. The compressor says it will produce 150# but in actuality it kicks off at about 130#. Has anyone had any problem running air drills and air wrenches at that pressure. I had a smaller compressor before and I ran the regulated air at around 100# through 1/4" air fittings and hose with no problems except my impact wrench was a little weak.
