Sourced for demanding diesel fleets and industrial power systems, the BOSCH 0445120037 common rail fuel injector is a genuine OEM component built to Bosch manufacturing standards. Belonging to the Bosch 120 Series, this injector is engineered to deliver accurate fuel metering, optimized atomization and improved combustion efficiency across medium-duty and heavy-duty diesel engines, resulting in lower emissions and extended engine service life.
This injector is fully cross-referenced under primary OE number 0445120037 and its recognized variants 0 445 120 037, 0445 120 037 and 0445120037RX, along with alternative numbers 0445120115, 0445120240, 5263306, 87538123, 3965750 and 4940171. It is compatible with Cummins QSL9, ISLe, ISC, QSC8.3 and C Series engines, as well as Case industrial and generator power applications, making sourcing straightforward for procurement and maintenance teams.
Constructed to withstand high fuel rail pressures exceeding 1600 bar, 1800 bar and 2000 bar depending on engine calibration, the unit maintains stable injection characteristics under harsh operating conditions. For reliable service, use only high-quality diesel fuel, avoid water contamination, replace fuel filters regularly and monitor injector correction values. During installation, replace the copper sealing washer and O-rings, clean the injector seat and fuel rail connections, verify coding requirements, follow OEM torque specifications and perform a leak-off test.
