Air Compressor

[parsonsj]

Did you just go through and sweat the joints in the copper like you would for normal water usage in the home?

Exactly. The 1" tubing is a lot easier to sweat if you step to the yellow can (insterad of the blue propane) since that makes a hotter flame. The M or L tubing is rated at 250 psi in annealed (after sweating) state, if I remember correctly. The ball valves are rated even higher than that.

It's been in place for years now, no problems to date. One final note: be sure and isolate the copper tube from the compressor with flexible line. Otherwise the vibration would likely lead to a failure of the sweated joints near the compressor. I used Aeroquip 12 AN push-on hose and fittings from the compressor to the copper tube.

I also run two compressors in times of high demand (like when my buddy comes over to use my blasting cabinet while I'm grinding or something). I use an isolater (or one-way valve) to keep the higher rated compressor from filling the lower rated compressor beyond its rating.
