15 FT 3-in-1 Commercial Truck Air Power Line Kit
Commercial Truck Air & Electrical Connection Standards: DOT FMVSS 106 & SAE Regulations
Commercial motor vehicle air and electrical lines in the United States are regulated by Federal Motor Vehicle Safety Standard (FMVSS) 106 and Society of Automotive Engineers (SAE) specifications. FMVSS 106 mandates strict tensile strength, burst pressure (minimum 900 PSI for air lines), and environmental resistance testing. SAE J1402 covers rubber brake hoses, SAE J844 governs nylon tubing, and SAE J560 dictates the standard 7-pole electrical pin layout for trailer ABS and lighting circuits.
Key Regulatory Standards Summary Table
