Description

The heavy-duty performance of your pneumatic brake system depends on high-quality components that ensure consistent air pressure. This complete air dryer valve is engineered to manage moisture and maintain optimal pressure levels within the braking circuit of heavy commercial vehicles.

301.02.0121 is the OE-equivalent of the WABCO 932 400 021 0 complete, air dryer valve used in DAF, PACCAR, and VDL heavy-duty vehicles. This component is designed to meet rigorous technical standards for reliability and long-term operation in demanding transport environments.

For workshop technicians, this assembly features specific port configurations including M22x1,5 and M16x1,5 VOSS connections to ensure a precise fit during installation. It is essential to check the heater voltage (24 V) and port dimensions against the existing system to ensure seamless integration and prevent leaks in the pneumatic line.

Maintaining the air dryer valve is a critical part of preventive maintenance for fleet managers. Regular inspections of the port connections and pressure stability help prevent system failures and ensure the longevity of the entire braking assembly.
