301.02.0041 Complete, Air Dryer Valve — SCANIA

The heavy-duty air dryer valve assembly provides essential moisture filtration and pressure regulation within the pneumatic braking system of heavy commercial vehicles. Engineered for durability, this component ensures stable air supply and protects downstream components from contaminants and moisture buildup.

301.02.0041 is the OE-equivalent of the WABCO 432 410 201 0 complete, air dryer valve used in DAF, FAUN, MAN, NEOPLAN, and SCANIA vehicles. It also serves as a high-grade replacement for several MAN-specific references including 81.52102-6019, 81.52102-6021, 81.52102-6023, 81.52102-6036, 81.52102-6049, 81.52102-6056, 81.52102-6059, 81.52102-6083, and 81.52102-9036. It is fully compatible with systems requiring Scania 2090009 or Faun 1658023 specifications.

Workshop technicians should verify the port configurations during installation to ensure a leak-free fit. The unit features Port 1 (M22x1,5) and Port 21 (M22x1,5) alongside a Port 22 (M12x1,5) design to meet standard heavy vehicle pneumatic requirements. Regular maintenance of the air dryer system is critical to prevent moisture accumulation in the braking circuit and ensure long-term system reliability.
