922 200 Compressor Ring for Cummins N14 / ISM

What does a compressor ring do?

This compressor ring is a vital component within the pneumatic air brake compressor system, ensuring effective compression and sealing within the cylinder. Manufactured from high-strength components, these rings are designed to withstand the intense thermal and pressure fluctuations inherent in heavy commercial vehicle operating environments.

Compatible vehicles and engines

This specific ring is designed for use in air brake compressors compatible with Cummins N14 and ISM engines. It is widely fitted to heavy-duty vehicles including Peterbilt, Kenworth, Volvo, International, Ford Trucks, and Western Star models. It also serves various applications in Freightliner, Sterling, and Orion Bus fleets.

Installation and maintenance

During installation, technicians should verify the piston diameter and groove clearances against the manufacturer's service manual to ensure a precise fit. It is recommended to inspect the cylinder liner for wear before installing new rings to maintain optimal air pressure within the braking system.

Maintenance guidance

Proper maintenance of the compressor piston and ring assembly helps prevent pressure drops in the pneumatic circuit. For optimal performance in heavy-duty applications, always consult your authorized distributor for precise fitment guidance.
