Hey Dennis, great write up. I'm trying to figure out a system setup like your and I was wondering what type of copper tubing you're using. Type L/Type M? I can't seem to find any information on copper tubing psi ratings anywhere. Our compressor is running 175 psi and we're nervous about the burst pressure of the tubing.

Here's some background:
175 psi compressor
The line is going about 75-80 feet from the compressor
We were thinking about 1/2in copper tubing (is that diameter going to affect anything?)

Thanks in advance.
