Question by: Ricky Y on May 1, 2025, 9:53 AM
hose gonna hold up running air brake lines on a Class 8 truck? got 1-3/8 inch lines and need something rated for it
Answer by: Customer Support on May 3, 2025, 7:58 AM
For air brake use, the working pressure tops out at 250 PSI and the temperature ceiling on air service specifically is 250°F, which is a step down from the 300°F rating that applies to fuel and coolant applications. The 1.38 inch ID matches your line size, and the FMVSS106 certification means it meets federal motor vehicle safety standards for exactly this kind of application. The polyester braid cover and wire braid reinforcement are built for the vibration and routing demands you find in commercial truck installations.

What kind of stuff can I run through this hose?
Answer by: Customer Support on Mar 18, 2026, 5:07 PM
This AQP hose handles air, gasoline, fuel, lubricating oils, and coolants. Just make sure to check the general guidelines for selection, installation, and maintenance.

got a 1-3/8" ID air brake line that needs replacing on an older rig, this the right hose for that size?
Answer by: Customer Support on Oct 29, 2025, 7:55 PM
A 1.38 inch ID matches a 1-3/8 inch line exactly, so yes, the bore size lines up for that application. The FC350-24 from Eaton Aeroquip is built specifically for engine and air brake service, and it carries FMVSS106 certification, which is the federal motor vehicle safety standard required for air brake hose used in highway vehicles. The black polyester braid construction holds up well in those under-hood environments where heat and movement are a constant factor.
