Useful Information

Description and Purpose:

The Cummins® Single Cylinder Air Brake Compressor (Part Number: 4318216) is an original replacement component built to the exact standards of the OEM. Intended for use with engines such as QSX15, QSB, ISB, ISX, it features water cooling, engine-driven lubrication, and a flange mounting system. This unit is supplied as a direct-fit solution for reliable air delivery in commercial brake systems.

Why Replacement is Important:

Air brake compressors are vital for maintaining consistent braking pressure. Using this genuine Cummins replacement restores original system performance and prevents pressure loss caused by internal wear, leaks, or reduced output in aging units. It’s an essential part of routine, safety-critical maintenance.

Impact on Vehicle Performance:

With its OEM design parameters, this compressor maintains factory-level air pressure support, essential for safe brake response under load. The precise dimensions and specifications (including piston stroke, port threads, and pressure capacity) ensure compatibility without modifications, supporting smooth and consistent vehicle operation.

Manufacturer Information:

Cummins® is a trusted name in heavy-duty diesel engine technology, known for quality-engineered components and long-standing OEM partnerships. Their replacement parts reflect the same reliability and performance standards found in their factory-installed equipment across global fleets.
