Question by: Jean B on Dec 8, 2025, 6:13 PM
does this hose hold up alright for air brake lines on a heavy truck, or is it more of a general engine hose?
Answer by: Customer Support on Dec 10, 2025, 3:47 PM
Air brake use is supported, but there's a pressure and temperature ceiling to keep in mind. For air service specifically, the rating tops out at 250 PSI and 250 degrees F, which is a bit lower than the general fluid limit of 300 degrees F. The hose carries FMVSS106 certification, which is the federal standard required for motor vehicle brake hose, so it's built with that application in mind. The 1.38 inch ID and single wire braid reinforcement make it a solid fit for heavy vehicle brake lines running within those parameters.

Does this hose meet the FMVSS106 standard for air brake lines, or is it just rated for general engine use?
Answer by: Customer Support on May 7, 2025, 6:56 AM
FMVSS106 compliance covers both engine and air brake applications for this hose. The FC355 series from Eaton Aeroquip carries that federal motor vehicle safety standard rating, so it qualifies for air brake service, not just general underhood routing. The 1.38 inch ID and up to 250 PSI working pressure are what you're working with, so confirm those fit your system before ordering.
