The Caterpillar 130-1804 Fuel Injector Nozzle is engineered as an OEM-quality replacement component for CAT C13, C15, and C18 diesel engine platforms, along with related 3406E and 3456 series engines commonly deployed in heavy-duty applications. Manufactured from high-strength alloy steel and processed through advanced CNC machining and precision heat treatment, this nozzle delivers micron-level dimensional accuracy and consistent spray geometry across demanding duty cycles. The component is designed to withstand modern high-pressure diesel injection pressures while resisting wear from abrasive fuel contaminants.

This injector nozzle provides stable fuel delivery, optimized atomization, and improved combustion efficiency, supporting reduced exhaust smoke output and balanced idle performance in industrial, construction, mining, and generator set operations. Direct-fit dimensions identical to original equipment specifications allow straightforward installation without modification, and the specialized material composition delivers long-term corrosion resistance for operation in harsh environments such as marine propulsion units, oilfield equipment, and off-highway machinery.

Compatible across excavators, bulldozers, wheel loaders, articulated dump trucks, mining trucks, diesel generator sets, standby power systems, and offshore support vessels, the 130-1804 nozzle serves as a reliable aftermarket solution cross-referenced to 10R-1804 and 130-1804C. It is suited for global B2B distribution channels serving field service workshops, equipment rebuild operations, and preventive maintenance programs requiring dependable fuel system restoration.
