- 【Material & Durability】Crafted from high-strength brass with precision machining, these DOT air brake fittings are built to withstand extreme pressure (up to 250 PSI) and resist corrosion, rust, and wear. The robust construction ensures long-term reliability in harsh environments, including heavy-duty trucking, trailers, and industrial pneumatic systems. Ideal for both commercial and off-road applications, these fittings meet SAE J1131 standards for superior performance.
- 【DOT-Approved Safety Compliance】Strictly certified by the U.S. Department of Transportation (DOT FMVSS 571.106), these fittings guarantee compliance with federal safety regulations for air brake systems. Each unit is rigorously tested for leak-proof performance, pressure resistance, and durability to ensure safe operation in commercial vehicles, buses, and trailers. DOT approval means you can trust these fittings for critical braking applications.

Perfect for replacing daily wear parts or building robust hose connections in air lines and copper tubing applications. Trusted performance where durability and safety matter.
