Type M is just fine, the only Copper you don't want to use is the soft coiled type but I have even seen that used successfully several times although I would strongly recommend not doing that.

Thanks guys! I'm getting started on it today. I just wanted to find out before I started soldering it together so I could exchange it if I had to.

I do not remember from two years ago when I researched it. IIRC, it came from a handbook of tables; I may have read them wrong.

When I looked again on the Internet, I found burst pressures in line with what you guys have been saying.

Probably a mistake caused by miss-matching with the pipe size, easy to do since as the diameter increases the pressure ratings decrease by a lot. This will not be any concern with the pressures and pipe sizes normally used for shop air line.

I have another question about my air line. I have my main line and drops figured out. My question is do I just tee off of my drops to install my filter and regulator? Each drop will have a water trap w/petock. Thanks for anymore info.

Whew.. Thought I was hallucinating or losing my memory.

I AM a little cautious when I turn off the valve (From the compressor to the lines, right at the compressor) and have to turn it on to pressureize hte lines.. I usually go kind of slowly then.
