301.02.0119 MERCEDES BENZ Complete, Air Dryer Valve

The 301.02.0119 is a critical component designed to manage moisture and maintain air quality within the pneumatic braking system of heavy commercial vehicles. This complete air dryer valve assembly is engineered with high-strength components to ensure long-term reliability under intense operational pressures. By effectively filtering air and managing pressure fluctuations, it protects downstream pneumatic systems from contamination.

This part serves as the OE equivalent of the MERCEDES BENZ 002 431 57 15 and WABCO 932 400 016 0 air dryer valve used in MERCEDES BENZ and EVOBUS vehicle systems. It is specifically engineered to meet the rigorous demands of heavy-duty transport, ensuring seamless integration with existing brake-suspension hardware and maintaining consistent system pressure.

For workshop technicians, this unit offers a precise fit with its specialized port configurations: Port 21 (M22x1,5), Port 22 (M16x1,5 VOSS), Port 11 (M10x1 VOSS), Port 23 (M16x1,5), Port 24 (M22x1,5 VOSS), and Port 4/25 (M12x1,5). Regular inspection of the heater functionality and port seals is recommended during routine brake system maintenance to prevent any air quality degradation.

Maintaining the integrity of the air dryer is essential for preventing moisture-related failures in the pneumatic circuit. This component provides a robust solution for fleet managers and service professionals seeking to minimize downtime in heavy commercial vehicle operations.
