Description

The high-strength components of this Complete, Air Dryer Valve ensure stable pneumatic performance within the brake system. Designed for heavy commercial vehicle applications, this unit manages air filtration and pressure regulation effectively to maintain system integrity under demanding operational conditions.

301.02.0044 is the OE-equivalent of the WABCO 432 410 005 0 complete air dryer valve used in MAN, SCANIA, and NEOPLAN vehicles. This part is engineered to meet strict technical standards for compatibility with WABCO brake-suspension systems and high-duty truck architectures.

Workshop technicians should note the specific port configurations: Port 1 and Port 21 utilize M22x1,5 threads, while Port 22 and Port 4/23 feature M12x1,5 threads. Regular inspection of the air dryer assembly and connection points is recommended to ensure optimal pressure maintenance of 10 BAR and prevent moisture accumulation in the pneumatic lines.
