Useful Information

Description and Purpose:

This Genuine Cummins Air Brake Compressor comes in new condition and is identified by Part number: 4318214RX. It is a single-cylinder, water-cooled, engine-lubricated unit engineered to supply stable air pressure to heavy-duty brake systems. Key features include a 3.35 in piston diameter, 2.20 in stroke, 145 PSI max pressure, and a durable mounting-flange design with a 28.7 mm crankshaft thread and multiple threaded ports for proper pneumatic routing. Cross reference: 4318214NX, 4318214

Why Replacement is Important:

Failing compressors often struggle to maintain pressure, causing slow buildup and inconsistent brake response. Timely replacement prevents unsafe pressure loss in demanding vehicle operation.

Impact on Vehicle Performance:

When operating correctly, the compressor delivers consistent airflow that supports stable braking on vehicles equipped with Cummins ISM, M11, and N14 engines, maintaining safe system performance across varying duty conditions.

Manufacturer Information:

Cummins® develops precision-engineered components designed to support heavy-duty torque output, stable combustion efficiency, and extended service intervals.
