Question by: Kirk M on Nov 12, 2025, 11:41 AM
Running tractor-trailer rigs and need to swap out the air brake lines. This hose rated for that kind of application, and what pressure does it hold up to?
Answer by: Customer Support on Nov 13, 2025, 2:32 PM
Tractor to trailer lines are exactly what this hose is built for, along with axle chamber lines and tractor service lines. It handles up to 225 PSI operating pressure, which covers standard air brake system demands. The 0.50 inch inner diameter and EPDM construction with polyester braid reinforcement give it solid durability for that kind of regular workload. It also carries SAE J1402 A, DOT AII, and FMVSS106 ratings, so it meets the certifications required for air brake use on commercial vehicles.
