25 17 10 Cylinder Head for Air Brake Compressors

What does a compressor cylinder head do?

A compressor cylinder head is a critical component within the pneumatic brake system, responsible for sealing the combustion or compression chamber and managing air flow. This part ensures that the air compressor maintains consistent pressure required for reliable braking performance in heavy commercial vehicles.

Vehicle and engine compatibility

This specific cylinder head is designed to be compatible with Cummins engines, including the ISB, ISC, and ISG12 series. It is widely used in a variety of heavy-duty applications across brands such as Freightliner, Kenworth, Peterbilt, and Volvo. It also fits several other commercial vehicle models to ensure reliable pneumatic system operation.

Installation and maintenance guidance

When performing maintenance or repairs, technicians should verify the discharge port thread type and bolt hole pattern against the existing unit. Because even slight deviations in flatness on the sealing face can lead to air leaks, it is essential to ensure the component matches the specific compressor architecture used in the vehicle's braking system.

Selection guidance

Check the compatibility list to ensure this component meets your specific engine requirements.
