DOT Air Brake Fittings 1/2" x 3/8" NPT Male, ANGRICHT Brass Air Line Connector with Spring Guard, 5 Pack Heavy Duty Hose Repair Fitting for Semi Truck Trailer
【Meets DOT Safety Standards】 Manufactured from high-quality brass, these fittings meet D.O.T. FMVSS571.106 specifications when used with SAE J1402 air brake hose. Tested to withstand up to 1200 PSI working pressure – far exceeding standard air brake system requirements – and perform reliably in extreme temperatures from -65°F to 250°F.
【Leak-Proof Precision Seal】 Precision-engineered threads and sealing surfaces create a tight, reliable connection that prevents air leaks, ensuring consistent brake response and reducing compressor run time to save fuel. No more wasted air or frequent system cycling.
【Easy 1-Wrench Installation】 Simple push-to-connect design requires just one standard wrench for a secure, reliable fit. The integrated spring guard prevents hose kinking at the connection point, extending hose life and reducing maintenance.
【Built to Last in Harsh Environments】 Made from solid brass with excellent corrosion and oxidation resistance, these fittings stand up to road salt, moisture, and extreme weather. Ideal for semi-trucks, trailers, air suspension systems, and shop air compressors.
【Complete 5-Piece Repair Kit】 Kit includes 5 brass male hose connectors with spring guards – enough for multiple air brake line repairs. Backed by our responsive after-sales support team ready to help with any questions about fitment or installation.
