The c-aterpillar 3412A series fuel injector, part number 7E-3384 (also referred to as 7E3384), is a high-performance common rail diesel fuel injector specifically developed for c-aterpillar 3412A series diesel engines, featuring excellent compatibility with 3500A series engines (including 3508, 3512, 3516) and a wide range of c-aterpillar heavy-duty equipment such as generator sets, industrial machinery, marine vessels, and mining equipment[1][3][6]. Crafted from high-quality alloy steel[2][7], this injector undergoes 100% strict factory testing before shipment to fully comply with OEM specific-ations, ISO 9001 and IATF 16949 quality standards[1][6], ensuring consistent performance, long-term durability, and perfect fitment. Adopting advanced common rail injection technology and precision-machined nozzle design, it achieves accurate control of fuel injection volume, timing, and atomization, thereby optimizing engine performance, promoting full diesel combustion, reducing fuel consumption, and delivering stable and reliable power output even under extreme high-load and harsh working conditions. Its robust structure and corrosion-resistant material make it highly adaptable to harsh environments such as dusty mining sites, high-temperature engine compartments, humid marine conditions, and industrial workplaces. Widely applied in c-aterpillar 3412A-equipped equipment and 3500A series-powered generator sets, industrial machinery, marine vessels, and mining equipment[6], it provides steady power support, seamless fitment, and effectively minimizes equipment downtime. As a cost-effective and trustworthy replacement part, it offers flexible order terms: MOQ starts from 1 piece[2][6], with tiered pricing (1-5 pieces at US$285 each, 6-19 pieces at US$265 each, ≥20 pieces at US$250 each[1][2]), 6-month warranty (flexible to extend to 12 months[1][6]), fast delivery within 3-10 working days (3-5 days for in-stock orders, 5-10 days for bulk orders[2][6]), and supports neutral, original, or customizable packaging[2]. It fully meets the maintenance and procurement needs of global customers in the power generation, industrial, marine, and mining industries, with multiple payment methods (T/T, Western Union, PayPal[6]) and shipping options (express, air, sea[2]) available to facilitate seamless global procurement.
