5257938 Cummins Compatible Twin Cylinder Compressor

This twin cylinder compressor serves as a critical engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it generates a higher volume of compressed air compared to single-cylinder models, ensuring that pneumatic reservoirs are filled rapidly even during high-demand operation.

This specific unit is compatible with Cummins systems and is engineered to meet rigorous service requirements. It features a water-cooled design with a water-cooled valve plate to maintain optimal operating temperatures under heavy load. The configuration includes an M26x1.5 air inlet and outlet port, alongside M16x1.5 water inlet and outlet ports, ensuring precise integration into existing pneumatic and cooling circuits.

Maintenance technicians should verify the integrity of the water cooling lines and the M26x1.5 connection points during routine inspections. Ensuring the through-drive mechanism is properly aligned helps maintain the efficiency of the 460cm³ swept volume performance over the service life of the component.

Check the compatibility list to ensure this unit meets your specific engine requirements.
