922 150 Compressor Piston for Cummins N14 & ISM Engines

What does a compressor piston do?

A compressor piston is a critical component within the pneumatic air brake system that facilitates air compression through reciprocating motion. This high-strength component is engineered to withstand the intense thermal and pressure cycles inherent in heavy commercial vehicle brake systems.

Compatible vehicles and engines

This specific piston is compatible with Cummins N14 and ISM engines. It is fitted to a wide range of heavy commercial vehicles including Freightliner models such as the FLD112 and FL80, Peterbilt 379 and 357 series, Kenworth T800 and W900, as well as Volvo, International, Western Star, and Ford Trucks. It also serves various bus applications like New Flyer and Orion Bus.

Installation and maintenance

When performing maintenance on the air brake compressor, technicians should verify the piston diameter and cylinder liner condition. This piston is designed to integrate seamlessly into existing repair kits to restore optimal pneumatic pressure. Ensure that all ring grooves are inspected for wear before installation to maintain system integrity.

Selection guidance

For optimal performance in heavy-duty applications, always ensure the replacement part matches the engine specifications. Consult your authorized distributor.
