Caterpillar C10 Series Fuel Injector 10R-0725 Product Detail Page Description Product Overview The 10R-0725 / 10R0725 fuel injector is a heavy-duty diesel fuel injector commonly used for Caterpillar CAT C10, C12, 3176C, and 3196 engine applications, depending on engine serial number, injector trim code, fuel system configuration, and machine build specification. Caterpillar’s official parts listing identifies 10R-0725 as a Cat® Reman remanufactured fuel injector and lists compatible model groups including 3176C and 3196 industrial engines and 3196 marine engines. The same official listing also shows 212-3464 as an alternate comparable fuel injector part with the same listed dimensions of 14.8 in length and 3.0 in height. This injector is designed for industrial diesel fuel delivery, high-pressure atomization, cylinder-specific fuel metering, combustion stability, low-emission performance, and reliable operation in heavy-duty engines used in trucks, industrial power units, marine propulsion, construction machinery, and equipment fleets. Important fitment note: 10R-0725 is widely listed in the aftermarket for CAT C10/C12, 3176C, and 3196 applications, but injector compatibility must always be confirmed by engine serial number, original injector part number, ECM calibration, injector trim file/code, and fuel system configuration before purchase or installation. Caterpillar also states that configuration changes may affect part fitment and recommends dealer verification before purchase.
