where to find plastic air lines?
im getting ready to repipe my garage and i was wondering about plastic air lines? Where can you find them? Should i just use copper or iron instead?

there was a post in the body forum i believe about those plastic air lines, i would probably just go with copper though if your comfortable with soldering.

Some of the newer plastic may be OK for air line but stay away from PVC. It is a no-no for air lines because it can shatter on impact.
My garage will be growing copper in the near future.

thanks. what thickness should i use for the copper or iron i run a lot of air tools all the time but i also paint should i run a smaller line for the paint?

I would not run a smaller line for paint. It's better to have the larger volume of air available and not need it than to find out at the last moment that you do not have enough for a particular set up.

Run the biggest one you can for the main line. It helps slow the air down so moisture settles out and it provides a surge capacity. I would think a minimum of 1/2 inch for branches if they are short and 3/4 inch for anything over 15 feet long. Remember to put drip stubs and drains on the ends of your outlets.

The plastic pipe that I have seen was kind of pricey. I went with schedule 40 black iron pipe. This link has a lot of good info on piping set up

Just a thought but if you want to have a real easy install and you don't need huge lines, use semi air brake tubing. this stuff comes in sizes up to 5/8 or 3/4 I think and its super easy to work with and it doesnt explode! Just a thought! I used this stuff on my air ride install and that was absolutly abused, temp changes, dirt, grimme, and abrasion. The only think it bad for is extreme temperature. I once used it as a temperary setup on a compressor and the heat produced by the compressor made the line go soft, it expanded to about 5 times its size(bulging at that the compressor) and still never burst. Compression fittings with "T"s would work for branch lines. Consider it; it may be what your looking for.
