11 25 50 Cylinder Head for Mercedes-Benz Compressors

What does a compressor cylinder head do?

A compressor cylinder head is the critical service part that closes the top of an air brake compressor cylinder block and carries the seats for the inlet and discharge valves. This component holds compressed air without leakage, routes it through the discharge port, and assists in managing compression heat. It is an essential part for rebuilding pneumatic compressors in place rather than replacing the entire unit.

Compatible vehicles and engines

This specific cylinder head is compatible with Mercedes-Benz vehicles including AXOR 2, Setra Series 400, and various models like Citaro, Integro, and Travego. It is designed to work with OM 457 LA and OM 457 HLA engines. The component is also suitable for Mercedes-Benz buses such as Intouro, Tourismo, and Conecto.

Installation and maintenance

When performing maintenance or repairs, technicians should inspect the cylinder head for cracks or uneven surfaces to ensure a proper seal. Proper installation of this head ensures the pneumatic system maintains consistent pressure required for safe braking operations in heavy commercial vehicles.

Troubleshooting and selection

The part is designed to meet the requirements of heavy-duty service environments, providing a reliable solution for workshop technicians and fleet managers looking to extend compressor life.
