Question by: Dustin J on Nov 30, 2025, 12:46 PM
got a 3/8 air brake line to replace, is this the blue Aeroquip Eclipse stuff the same type used on trucks and trailers?
Answer by: Customer Support on Dec 2, 2025, 6:04 AM
For truck air brake systems, trailer air brake systems, and auxiliary air systems, this tube is spec’d as SAE J844D Type 3B in blue and it is DOT FMVSS 106 compliant. It’s also listed for formed tubes and for formed or straight air brake harness assemblies, so it fits that common 3/8 air brake tubing use case.
