301.03.0012 KNORR-BREMSE Complete, Air Dryer Valve

The technical function of this complete air dryer valve is to ensure the pneumatic integrity of the heavy commercial vehicle brake system by removing moisture and contaminants from the compressed air stream. Designed with high-strength components, it maintains consistent pressure regulation under demanding operating conditions.

301.03.0012 is the OE-equivalent of the KNORR-BREMSE II19208, II19208181, II19208AT, II19209N50, K022746, and LA 8211 parts used in KNORR-BREMSE and MAN systems. This component is engineered to meet strict technical standards for seamless integration into existing heavy commercial vehicle architectures.

For workshop technicians performing maintenance or system overhauls, this unit features specific port dimensions including M22x1,5 and M12x1,5 to ensure precise assembly. It is essential to verify the port configurations and pressure ratings during installation to maintain optimal pneumatic performance and prevent system failures in heavy-duty trucks and buses.
