412 100 806 2 Compatible Compressor Cylinder Head

What does a compressor cylinder head do?

The compressor cylinder head serves as the primary sealing component situated atop the air brake compressor cylinder block. By sealing the compression chamber from above, this component allows workshop technicians to rebuild a compressor in place rather than replacing the entire unit. It functions as the structural housing for inlet and discharge valve seats, internal air passages, and essential cooling cavities.

Compatibility and application

This component is specifically designed for compatibility with WABCO systems. It ensures the compressor maintains proper air output and stable operating temperatures during heavy commercial vehicle service. Professional technicians use these heads to restore pneumatic performance in various heavy-duty engine configurations.

Installation and maintenance

When performing maintenance, ensure the cylinder head is inspected for surface integrity. Proper installation of the head and its associated gaskets is vital to prevent pressure leaks within the pneumatic circuit. For optimal performance, always verify that the port sizes and mounting points align with the existing compressor architecture during the rebuild process.

Selection guidance

Selecting a high-strength replacement helps maintain consistent air pressure delivery across the braking system. Consult your authorized distributor to ensure exact fitment for your specific compressor model.
