Perkins original Perkins 370-7281 replacement fuel injector new injector original new injector

The Perkins C4.4 fuel injector 370-7281 is engineered as a direct OEM equivalent replacement for Perkins industrial diesel engines. Manufactured from hardened alloy steel with an anti-corrosion surface treatment, this injector is CNC-machined to meet precise OEM tolerances. It integrates seamlessly into the high-pressure common rail fuel system, with an operating pressure range of 1800–2200 bar and a calibrated flow rate of 60–65 L/h at 200 bar, ensuring consistent fuel delivery across demanding duty cycles.

Featuring a multi-hole spray nozzle and electronic control actuation, the 370-7281 injector delivers optimized fuel atomization for uniform combustion, improved power output, and reduced NOx and particulate emissions. The solenoid or piezoelectric actuator responds to ECU signals for precise control over injection timing, quantity, and duration. Its robust construction provides exceptional wear resistance and long service life in heavy-duty applications such as construction, mining, agriculture, and power generation.

This injector is fully compatible with Perkins C4.4, C4.4 ACERT, C4.4 Generator, C4.4 Industrial, and C4.4 Agricultural engines, and fits a broad range of equipment including wheel loaders, excavators, backhoe loaders, telehandlers, skid steer loaders, road rollers, generator power units, and tractor series. Cross-referenced with 209-4394, 320-7281, and 0R-7281, the 370-7281 provides a reliable, cost-effective replacement solution backed by a 12-month or 1000-hour warranty.
