Wouldn’t it be great to have access to compressed air throughout the garage or shop without having to haul and set up your compressor everywhere you need it? Well, it doesn’t take as much as you think to make it happen. Here is a simple, rudimentary way of setting up the workshop to do just that.
What Kind of Pipe?
If you’re considering PVC pipe, don’t. If the PVC broke under pressure, the plastic would burst and send a salvo of splintery shrapnel all over the place. For a home shop, we recommend copper– 1) you won’t run into the same problem; 2) it won’t corrode; and 3) it’s readily available at the local home improvements stores. For the fittings, you’re going to want to find a refrigeration solder designed for 200+psi working pressure, such as Stay-Brite #8, which installs easily with a standard Butane or Propane Torch, as well as the Stay-Clean flux to spread it out (don’t cross fluxes).
(If you don’t want to solder, use black steel pipe. Measure the pipe runs and buy exact lengths– the home improvement stores will cut and thread them for you. The nice thing about air compression lines is, unlike water or gas lines, they don’t need perfect joints, so it’s OK if they leak a little. For the purpose of this article, we’re going with the first choice– copper)
Here are the necessary tools you’ll need to do this project:
You will also need a wire brush handy for cleaning the copper joints.

We recommend you run your main line high, but exposed, up near the ceiling, with a drop anywhere you think you’ll want an air hose. At the bottom of the drop, install a TA ball valve at the top and bottom of the T, and a quick coupler on the 90 (facing, of course, away from the wall).
There are plenty of sites that go in greater detail regarding connections and PSI, etc. We would advise you to look for the most authoritative direction (if you find multiple sources that concur, even better!). The subject is diverse and there are lots of possibilities for configuration. Good luck with your installation!
