Description
This compressor cylinder head acts as the cast service component that sits on top of an air brake compressor's cylinder block, sealing the compression chamber from above. By replacing this component, workshop technicians can rebuild an existing compressor in place rather than replacing the entire unit, which significantly optimizes maintenance efficiency.
This part is compatible with WABCO systems. It is designed to house the seats for the inlet and discharge valves, manage internal air passages, and facilitate cooling through integrated cavities. Proper installation ensures stable air output and efficient temperature regulation during heavy-duty operation.
When performing a rebuild, technicians should inspect the cylinder block surface and valve seats to ensure a proper seal. Selecting the correct head type—whether it is an air-cooled or water-cooled design—is essential to match the specific architecture of the compressor being serviced.
Consult your authorized distributor.
