Caterpillar original Diesel Fuel Injector: 295050-1810, for heavy duty diesel engine application, 20R-2479, 295050-0411, 418-3229, OEM Replacement Excavator Fuel Injector Pump original new injector

Designed to meet stringent heavy-duty diesel engine replacement standards, the CAT 295050-1810 is an OEM-grade common rail diesel injector purpose-built for Caterpillar C4.4 engine platforms. It matches verified cross-reference numbers across Denso, CAT, Perkins and industrial remanufacturing databases, including 295050-1811, 418-3229, 392-1368, 20R-2479 and T413878, with confirmed compatibility with Caterpillar C4.4, C4.4 ACERT and Perkins 1204E industrial diesel engines.

This electronic high-pressure common rail injector operates via ECU-controlled signals that precisely regulate injection timing and fuel delivery quantity. Its precision-machined nozzle optimizes fuel atomization for more complete combustion, while high-grade alloy steel construction delivers corrosion resistance and stable high-pressure injection performance. The low-leakage design improves fuel economy, reduces exhaust emissions and extends service life, supporting consistent, reliable engine output across demanding industrial workloads.

It fits a broad portfolio of heavy-duty equipment across construction, mining, agriculture, power generation, material handling and pump/compressor sectors, including excavators, loaders, generators, tractors and forklifts. Designed for direct replacement, installation must follow CAT manual torque specifications, with recommended leak testing, common rail pressure checks and ECU calibration after fitting. Backed by a 12-month standard warranty, it offers neutral or custom packaging and worldwide shipping for B2B parts distributors, repair providers and equipment fleet operators.
