Who sells DOT stamped copper tubing so I can replace my air line from the new compressor I've installed for the storage tanks? My Google is not working..
thanks
thanks

Huh, I guess the copper in my 1953 wrecker is due to fail soonCopper NG- work hardens and becomes brittle.
Steel tubing.
I used this in my deuce when I swapped from the dual piston compressor to the single. Its been fine for 2yrs.Just the stuff in the plumbing section at the hardware store is about all you're going to find. It should work fine.
That's exactly what I did with mine, for the same reasons. Works great!You could go with some PTFE stainless steel line like I did. I installed an auxiliary air-tank and got rid of the old copper line. It had a lot of bangs and bumps and gashes on it. I don't have any pictures of where it comes out of the compressor, if you want I can take some tomorrow . You don't have to go as long as I did either. Just go to the frame (about 2ft long) and then use a DOT nylon hose to JIC junction.

For one it is thicker and I'm sure annealed. By going with a flexible line like the PTFE hose I'll never have to worry about work hardening the hose like copper does. It will also take a "hit" from some random object (rock flying up from the road) without putting a gash or hole in it. Since it is stainless steel lined it can take a hit and will never rust. I also installed a heavy duty hose protective sleeve on it (double protection). Our buses used to run copper lines from the compressor to the "ping" tank. Now all the buses use PTFE stainless steel hose. There is a reason for that. I have not had to replace a single one of these lines since the transit department started using them. On the old style copper lines it was fairly common to replace a line at least once a week on a buss. For a safety item like the air-system I don't want to take chances.
