what's the wall thickness on this green air brake tubing, and is 250 feet enough to do a full trailer harness assembly?
Answer by: Customer Support on Jan 15, 2026, 7:18 AM
Wall thickness runs 0.09 inches, and the OD is 0.75 inch. Whether 250 feet covers a full trailer harness depends on your layout, but this is a bulk coil intended for exactly that kind of work. Formed and straight air brake harness assemblies are listed right in the application spec, so you're in the right place for that job.

got a roll of this green stuff, is it meant for air brakes on trucks and trailers or is it more for shop air

Built for vehicle air systems, it fits right in on truck air brake systems, trailer air brake systems, and auxiliary air systems. It is also commonly used when you are building formed tubes or putting together formed and straight air brake harness assemblies.
