Designed for the CAT 3512B diesel engine platform, the 370-7282 fuel injector (OE 3707282) is a precision fuel injection nozzle assembly responsible for delivering accurately metered, finely atomized diesel fuel into the combustion chamber. As a core component of the engine's fuel system, it directly influences combustion efficiency, power output, fuel economy, and emissions performance. Maintaining consistent injection quality is therefore essential to keeping the 3512B running reliably under demanding, heavy-duty operating cycles.

This injector is offered as a universal replacement covering an extensive range of cross reference numbers, including 20R-2478 / 20R2478, T409982 / T4-09982, Denso-type references 295050-0401 / 2950500401 and 295050-0400 / 2950500400, and CA3707282. Such broad interchangeability simplifies parts identification, procurement, and inventory management for distributors, engine rebuilders, and fleet maintenance teams, while reducing the risk of ordering errors. The injector supports CAT 3512B engines deployed in industrial power generation, marine, and mining equipment applications.

Manufactured to OEM standards, the injector assembly delivers the fit, spray performance, and durability required for heavy-duty service. For B2B buyers, it represents a dependable sourcing option that supports engine overhauls, scheduled maintenance programs, and urgent replacement needs, helping to minimize equipment downtime, control operating costs, and protect the service life of high-value Caterpillar power assets.
