Description

What does a compressor cylinder head do?

This compressor cylinder head functions as the cast service component that sits atop the cylinder block to seal the compression chamber from above. It is a vital component for maintaining proper pneumatic pressure and regulating internal temperatures during operation.

Compatible vehicles and engines

Designed specifically for compatibility with BMC compressors, this part allows workshop technicians to rebuild air brake units in place rather than replacing the entire assembly. It is also fitted to various BMC trucks and heavy commercial vehicles.

Installation and maintenance

During installation, technicians should inspect the valve seats and internal air passages to ensure a perfect seal. Proper seating of the head is essential to prevent pressure leaks and maintain consistent air delivery for the braking system.
