25 25 10 Cylinder Head Compatible with Cummins

What does a compressor cylinder head do?

A 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.

Compatible vehicles and engines

This component is engineered for high-performance operation in various heavy commercial vehicle applications. It is compatible with Cummins ISBe and ISLe engines, fitting models such as Ford Trucks Cargo, KamAZ 6520, and Yutong ZK6118. This part is essential for maintaining optimal air pressure within the pneumatic braking system.

Installation and maintenance

For professional technicians, selecting the correct cylinder head ensures proper valve seating and pressure stability. When replacing this component, ensure the compressor's discharge port and mounting surfaces are inspected to prevent leaks. This part allows for efficient rebuilding of existing compressors in place rather than requiring a full unit replacement.
