Description

This high-strength component serves as a critical element within the pneumatic brake system, ensuring the continuous removal of moisture and contaminants from the compressed air stream. Designed for heavy-duty commercial applications, it maintains stable air pressure and protects downstream components from damage.

The 301.03.0059 is the OE equivalent of the KNORR-BREMSE K007770N00, K007771N50, and LA8509 air dryer valves used in heavy commercial vehicle braking systems. This part is specifically engineered to meet the rigorous demands of industrial-grade pneumatic circuits.

Technical specifications include specialized port sizes such as M22x1,5 for primary connections and M12x1,5 for auxiliary lines. Technicians should verify all port thread types and ensure the 11 BAR pressure rating aligns with the existing system requirements during installation to maintain optimal service intervals.

Regular inspection of the air dryer assembly is recommended to prevent moisture buildup in the braking system. This component ensures reliable performance in demanding environments through its precision-engineered construction.
