Air line colors

[Fat Brian]

Is there any standard for what color the air hoses to the trailer should be?  I have black, white, red, and green wire so I have some options there.

Left side emergency and supply always red, right side service and application always blue with coiled plastic lines. Rubber lines normally black with red and blue id on gladhands. Electric are black pre abs green post abs.

Thank you, I can work with that.

I work at Utility Trailer Mfg. The above info is correct.  Here is some helpful info too. Standard airline size is 3/8 od, some companies order 1/2 inch airlines. 5/8 airlines are either black or a lime green color. ABS harness are orange from where they drop out of the raceway to the rear sub assembly.( rear axles).

Brake cans or actuators are black with silver or gold 1/2 caps. Ours are never painted, DOT regulations on that part.

On our trailers the electric and airlines run down the center on reefers and down the roadside on dry vans.

Roadside = drivers side or left side

Curbside = passenger side or right side

It was confusing at first but after a while it is not left or right it is road and curb. I catch myself doing alot especially when people look at you like what the heck did you say. My wife is used to it now after 19 years with Utility.
