I need to replace my copper air line for my ARB locker, I'm having a hell of a time finding the proper sized copper tubing.
I believe that the existing copper line is 6mm, most of the stores here in town carry 1/8"
The 1/8" outside diameter is real close but the inside diameter is smaller.
has anybody used the 1/8" line? any problems? I would like to use compression fittings for easier future repairs as well.
