The Perkins C9.3 Fuel Injector 169-7408 is an OEM-specification common rail injector engineered for the Perkins C9.3 high-pressure diesel engine platform. It is designed to deliver precision fuel metering across all load conditions, ensuring the correct fuel quantity reaches each combustion event for consistent engine performance. Superior atomization technology produces ultra-fine fuel droplets that promote efficient combustion, while electronically controlled ECM solenoid actuation allows real-time adjustment of injection timing and duration.

This injector supports common rail working pressures of approximately 1,800–2,200 bar, making it suitable for demanding heavy-duty applications. It is built with corrosion-resistant materials to perform reliably in humid environments, coastal regions, and high-temperature operating conditions. Optimized combustion characteristics help reduce black smoke, particulate matter, NOx emissions, and overall fuel consumption, supporting both operational efficiency and emissions compliance for industrial users.

Compatible with a wide range of Perkins-powered equipment—including excavators, wheel loaders, motor graders, compactors, generator sets, mining machinery, and industrial power units—the 169-7408 injector is qualified across the construction, mining, power generation, marine, agriculture, and oil & gas sectors. Long service life is engineered for continuous operation in harsh field conditions, providing dependable fuel system performance for Perkins C9.3 engine operators worldwide.
