25 03 50 WABCO SS318 Cylinder Head

The precision-engineered cylinder head serves a critical role in the air brake compressor system, ensuring stable pressure regulation and structural integrity under high-load conditions. This component is manufactured using heavy-duty grade materials to withstand the rigorous thermal and mechanical stresses typical of heavy commercial vehicle operations.

25 03 50 is the OE-equivalent cylinder head used in WABCO SS318 and CUMMINS ISX systems. This part is fully compatible with WABCO (911 153 921 2) and CUMMINS (4089206) specifications, ensuring precise fitment for workshop technicians performing engine or compressor overhauls. Its design focuses on maintaining optimal pneumatic efficiency within the air brake circuit.

For workshop professionals, this part provides a reliable solution for maintaining compressor-related air brake systems. Regular inspection of the cylinder head and surrounding seals is recommended during scheduled maintenance to prevent pressure drops. This component is specifically engineered to meet the technical requirements of heavy-duty engine architectures like the CUMMINS ISX, providing a long-lasting service life in demanding environments.
