air line color code

[rayshound]

Does anyone know the air line color code? I once had a Gilling & took parts off of a bluebird and both had different color air lines. Both manuals, Gilling & BB both had the same color code chart. Both busses & manuals are gone. Does anyone have such a chart, thanks Ray

I am not aware of any "industry standard" codes.  Many big rigs have all-black piping, some a mix
of  black, red, blue, green, etc.

Individual companies may have their own codes, but I've never heard of anything specific.  The
air-brake engineering manuals put out by Bendix don't mention any color codes, but mine is
several years old...
