25 28 50 Cylinder Head for Air Brake Compressors

What does a compressor cylinder head do?

This compressor cylinder head is the cast service part that closes off the top of an air brake compressor's cylinder block and carries the seats for the inlet and discharge valves. It holds the piston's compressed air without leaking, routes it out through the discharge port, and carries away part of the compression heat from the body. It is used on single- and twin-cylinder, air-cooled or water-cooled compressors fitted to heavy commercial vehicles.

Vehicle and engine compatibility

This component is compatible with Cummins ISLe engines and is also fitted to Ford Trucks Cargo, KamAZ 6520, Dongfeng Duolika, and Yutong ZK6118 vehicles. It also serves various models including Paz 3204, Zhongtong LCK6118, and Iveco Bus Metro, ensuring reliable performance across diverse heavy-duty applications.

Installation and maintenance

When performing maintenance on the pneumatic system, technicians should inspect the cylinder head for signs of thermal stress or leaks around the valve seats. Proper installation ensures that the compressor maintains stable pressure levels under sustained high loads. Check the compatibility list for specific engine requirements.

System reliability

Maintaining the integrity of the cylinder head is essential for preventing pressure drops in the braking system. This part allows for an efficient rebuild of existing compressors in place rather than requiring a complete unit replacement.
