Engineered as a direct-fit OEM replacement for Caterpillar 3412 series diesel engines, the 173-9379 original fuel injector is a high-precision industrial-grade component built to align with strict Caterpillar performance specifications. Listed in the official OE database under part numbers 7W-3379 and 173-9379, it also supports cross-replacement with part numbers 1739379, 326-2150, 7W3379 and CAT173-9379, making it suitable for both new engine installations and high-performance replacement use cases across global industrial diesel fleets.
Constructed from high-strength hardened steel with corrosion-resistant surface treatment, this injector delivers reliable performance in extreme operating conditions ranging from -40°C to 120°C. Its mechanical/electronic regulation system maintains consistent fuel flow and 1500–2000 bar injection pressure across all 12 cylinders, while the precision-machined single/multi-hole nozzle produces an optimized spray pattern for superior fuel atomization. This design boosts combustion efficiency, reduces fuel consumption and exhaust emissions, and supports stable long-term engine operation under heavy loads.
Validated through both OEM and aftermarket reliability testing, this injector is compatible with a wide range of heavy-duty equipment across core industrial sectors, including construction, mining, marine, industrial power, agriculture and oil and gas operations. It comes with a 12-month warranty, and can be installed and serviced following official Caterpillar calibration guidelines to minimize downtime for B2B fleet operators and equipment maintenance providers.
