The Perkins 3412 Series Fuel Injector 232-1175 is engineered as a direct OEM replacement for high-output V12 diesel platforms including the 3412, 3412B, and 3412C engine models. Built from high-grade hardened steel, this injector is designed to withstand continuous high-pressure diesel injection cycles in demanding industrial environments. Its precision-machined nozzle delivers complete fuel atomization, contributing to improved combustion efficiency, reduced exhaust emissions, and consistent engine performance across the 500–850 HP operating range.

Compatible with cross reference part numbers 10R-7222, 10R-7223, and 2321175, the 232-1175 injector offers broad interchangeability for industrial generators, marine propulsion systems, mining equipment, construction machinery, oil and gas installations, and agricultural heavy machinery. The unit operates within an optimal pressure range of 1800–2000 bar, features a 140–160° spray angle, and weighs between 1.5–2.0 kg. Corrosion-resistant construction ensures dependable service in marine, dusty, and high-humidity operating conditions where original Perkins specifications must be maintained.

Installation follows standard torque specifications of 35–45 Nm with proper cylinder head port alignment. For maximum service life, Perkins-approved diesel fuel is recommended, and injector inspection is advised every 500 operating hours. Ultrasonic cleaning is suggested for severe carbon deposits, and the 12-month / 1000+ operating hour warranty reflects the long-term reliability engineered into every 232-1175 unit supplied for Perkins 3412 series applications.
