D.O.T. AIR BRAKE NUTS

D.O.T. air brake nuts are components of air brake systems in commercial vehicles that are designed to connect air brake lines and ensure a leak-proof transmission of compressed air. The "D.O.T." designation indicates that the nuts meet the safety standards set by the Department of Transportation (D.O.T.). These fittings are essential for controlling a vehicle's stopping power and are required for large, heavy vehicles like trucks, semi-trailers, trailers, buses, and railroad trains. A typical truck can have 60 to 100 air brake tube fittings.
