301.04.0004 DAF Cartridge, Air Dryer Valve

The 301.04.0004 Cartridge, Air Dryer Valve is a critical component designed to maintain the integrity of the pneumatic braking system by removing moisture and impurities from the compressed air stream. This high-strength component ensures consistent air quality and prevents system corrosion in heavy commercial vehicles.

This product is developed to be compatible with DAF (1681575, 1821580, 1891431), SCANIA (2131091), WABCO (4329012462), and KNORR-BREMSE (K039455) systems. Specifically engineered for models such as the DAF CF 85 (MX Series), XF 105, and CF 75/65 series, it serves as a reliable OE equivalent for professional maintenance. 301.04.0004 is the OE equivalent of the DAF 1681575, 1821580, 1891431, KNORR-BREMSE K039455, SCANIA 2131091 and WABCO 4329012462 used in the vehicle's brake system.

For workshop technicians, this cartridge features a precise M41x1,5 port size to ensure a secure fit within the air dryer housing. Regular inspection of the air dryer assembly and timely replacement of the cartridge are essential to prevent moisture buildup and maintain optimal pneumatic pressure within the braking circuit.

Regularly monitoring the air dryer performance helps prevent long-term damage to pneumatic valves and actuators within the heavy commercial vehicle braking architecture.
