It is also not UV protected. If you run it in the shop exposed to light, it will rot eventually.
I know I am REALLY the oddball here. I wanted something easier than black pipe. Even though I have my own threader, it is a pain cutting and threading to make it look good. When running 100 foot of natural gas line, I had to use black pipe. What a pain. It is heavy and difficult for an old man to work with.
I came across a great deal on several hundred feet of 1/2 in air brake line. Very flexible and easy to work with. If you heat the end, it stretches easily enough to get it over a pex line fitting.
It is UV protected and has a burst pressure of 1300 psi.
Talk about easy. Cut with pex cutters, heat the end with a heat gun for 20 seconds, use a brass pex fitting. Also found deals on bulk pex fittings and clamps.
My compressor has an aftercooler. I ran three loops up the wall and back down before any of the lines headed into the shop area. I have a fancy three stage dryer set up, but have never installed it. Each loop on the wall has a ball valve at the bottom. I open them every once in awhile but have NEVER seen moisture in the system. Sandblast for an hour straight, and never get moisture.
