412 100 800 2 WABCO Compatible Compressor Cylinder Head

What does a compressor cylinder head do?

This compressor cylinder head acts as the critical service component that sits atop the air brake compressor cylinder block, sealing the compression chamber from above. It is engineered to allow workshop technicians to rebuild a compressor in place rather than replacing the entire unit. By providing stable valve seating and internal air passages, this component directly governs both the air output and the running temperature of the assembly.

Vehicle and system compatibility

This part is compatible with WABCO systems. It serves as a precise replacement for original components used in heavy commercial vehicle braking systems, ensuring efficient pressure regulation and durability under high-load conditions.

Installation and maintenance

When performing maintenance, technicians should inspect the valve seats and cooling cavities within the head to ensure optimal performance. Proper installation of the cylinder head is vital to maintaining the integrity of the compression chamber and preventing air leaks in the pneumatic circuit.

Selection guidance

Selecting the correct cylinder head ensures compatibility with specific compressor architectures, whether single-cylinder or twin-cylinder configurations. Consult your authorized distributor.
