This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment I haven't found any PSI specs on copper either but I'm sure a local = commercial plumbing supply can tell you. I have a vertical compressor = that maxes out at 135 and the piston pump transfers the air to the tank = via a piece of 1/2" soft copper so I guess copper is okay. Let us know = if you find any specific data.

I haven't been able to get pressure rating anywhere. = I spent an hour on the net and looked at McMaster Carr etc. Lotsa = rhetoric but no specs. I'm sure the rating depends on the diameter. I give up. Guess I'll just go with 1/2 inch blue and hope it works. ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
