Colored Air Line

[robert teed]

Seems to Me plastic would be the way to go. If mine
are the original there still working good. 25 year
test works for me.

Are you guys making one big mistake. I was told at Las Vegas by some of
the "experts" to forget that terrible plastic air line and use copper
lines. The copper fittings and connections are also supposed to be far
superior as far as leaks go. I haven't gotten around to plumbing the
system yet but my plan has been to go copper, based on their advice.
What's the concensus?

Be advised that copper can be more trouble than it is worth. As design
engineer that designs reviews air, gas and hydraulic systems it is
subject to stress failure and excessive corrision both inside and out.
If you wish to go to a metal type lines for your coach they will require
well thought out layout and support to prevent wearing of holes caused
by coach movement. Rubber grommets and standoff should be used to
prevent wear and failure. 2 lines should never be tied to each other.
I would recommend only a 304 or 316l stainless tubing. Even a good
grade of steel tubing would be more durable.

Don't listen to those "experts" Phil, they will get you KILLED! First the
copper line does not have a high enough burst pressure, and second it would
break from any flexing in a short while. Brass fittings are ok but DOT
approved nylon line is the only way to go. It is very rugged, relatively
cheap and lasts a long time. It was designed correctly by GM engineers and
should stay that way.
