Precision-built as a mission-critical diesel fuel system component, the Caterpillar (CAT) 10R-1273 Electronic Unit Injector is engineered exclusively for the C15 engine platform to meet strict original equipment (OE) performance specifications. It supports cross-replacement with part numbers 249-0713 (2490713) and remanufactured part number 20R-8063 (20R8063), and is compatible with all C15 variants covering industrial, truck, generator, marine, petroleum and mining configurations for heavy-duty equipment.

Operating within the Electronic Unit Injection (EUI) system, the injector responds to ECM signals to pressurize fuel, lift the nozzle needle and deliver finely atomized fuel into the combustion chamber for controlled, efficient combustion. It features a precision nozzle, hardened wear-resistant components, corrosion-resistant materials and high-pressure fuel delivery capability, with 100% pre-shipment testing. These design elements enable precise fuel metering, lower fuel consumption, reduced exhaust emissions, enhanced power output and extended engine service life.

The injector is available in new and remanufactured conditions, with neutral or customized OEM packaging and a 12-month warranty. It serves construction, mining, heavy transportation, marine, power generation, oil & gas, agriculture and infrastructure sectors, with strict quality control, global shipping and technical support available for B2B buyers. Following official installation and maintenance guidelines ensures reliable long-term operation.
