2500 260 001 CUMMINS Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide consistent pneumatic pressure within the vehicle's air brake system. Designed as a robust component for heavy commercial vehicle engine systems, it utilizes a water-cooling method to maintain optimal operating temperatures during intensive service cycles.

The 2500 260 001 is the OE equivalent of the CUMMINS 3975798 air compressor used in CUMMINS ISBe, ISDe, and ISLe engine configurations. This high-strength component features a 225cm³ swept volume and specific port dimensions including an M26x1,5 air inlet and M22x1,5 air outlet to ensure precise fitment and performance.

Maintenance technicians should monitor the water cooling connections—specifically the M16,5 inlet and outlet ports—to ensure the thermal management system functions correctly. Regular inspection of the through-drive and the ESS feature functionality is recommended to prevent system downtime in heavy-duty fleets.

By providing exact dimensional compatibility with original specifications, this part supports the efficient operation of the engine's pneumatic subsystems. It is an essential component for maintaining the air brake pressure required for heavy commercial vehicle safety.
