3965888 CUMMINS Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide reliable air compression for heavy commercial vehicle pneumatic systems. Featuring a robust design with a Ø80.00 bore and 45mm stroke, it ensures consistent pressure delivery under demanding operating conditions. The water-cooled configuration and high-strength components make it a durable choice for maintaining system integrity in heavy-duty applications.

3965888 is the OE equivalent of the CUMMINS 3965888 single cylinder air compressor used in the CUMMINS ISB engine. This component is designed to meet strict technical requirements for fitment and performance within the engine's air supply architecture, ensuring seamless integration with existing hardware.

For workshop technicians, this unit features an M26x1,5 air inlet port, an M22x1,5 air outlet port, and an M10x1 unloader port. The water-cooled system utilizes M16x1,5 ports for inlet and outlet to manage thermal loads effectively. Proper installation should follow standard workshop procedures for water-cooled compressor assemblies to ensure the through-drive and cooling paths are fully operational.

Regular maintenance of the air-cooling system and checking the integrity of the M26x1,5 inlet connection is recommended to prevent pressure fluctuations. This part is specifically designed for heavy-duty service environments where consistent air-brake system support is critical.
