Caterpillar original For Caterpillar C4.4 C7.1 Engine Diesel Fuel Injector 370-7280, 295050-0331 Replacement for OEM, 370-7287 for 20F Excavator Loader Cross Reference 418-3229 original new injector

For fleet managers, maintenance teams, and parts distributors supporting Caterpillar-powered heavy equipment, the CAT 370-7280 fuel injector is a precision-engineered diesel common rail component built for reliable industrial operation. It is an OEM-equivalent replacement for the full Caterpillar C4.4 engine series (including ACERT, industrial, and generator variants) and selected C7.1 platforms, with verified compatibility across listed CAT excavator, material handler, generator set, and industrial engine models. Cross-referenced CAT reman and DENSO part codes simplify part matching for procurement and repair teams.

As an electronically controlled high-pressure common rail injector, the 370-7280 responds to ECU signals to deliver precisely metered fuel with an optimized spray pattern, boosting combustion efficiency, cutting fuel consumption and emissions, improving cold-start performance, and reducing engine noise. It features OEM-calibrated flow rates, a precision atomization nozzle, corrosion-resistant build, and industrial-grade durability to sustain stable power output and consistent fuel economy across long service cycles.

This injector supports heavy-duty sectors including construction, mining, agriculture, power generation, and general industrial operations. It complies with standard OEM installation procedures, and routine maintenance practices (regular filter replacement, fuel quality monitoring) help extend its service life. Global shipping, neutral packaging, and customized branding options are available to meet international B2B buyer and service provider needs.
