PMC-TECH specializes in the R&D and manufacturing of fuel injectors and diesel engine components. We have just completed an order for Caterpillar C9 fuel injectors (Model 387-9433) destined for a maintenance project involving mining excavators in Australia.

Designed primarily for 330D and 336D excavators, these 387-9433 injectors undergo comprehensive testing on high-pressure test benches. We strictly verify parameters such as injection pressure, fuel delivery volume, and return flow, ensuring seamless installation without the need for additional on-site calibration.
Key components—including the valve body, sealing assembly, and nozzle—are assembled and calibrated using high-standard processes to minimize failure rates in high-temperature environments. These injectors are ideal for heavy-duty mining applications and machinery retrofitting, enhancing equipment rental profitability and meeting the needs of maintenance clients requiring frequent, bulk replacements.

We welcome interested parties to visit our factory, where we look forward to hosting you.
