The c-aterpillar 3412A series fuel injector, part number 7W-2269 (also referred to as 7W2269), is a high-reliability common rail diesel fuel injector specifically engineered for c-aterpillar 3412A series diesel engines, boasting 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 excavators[1][3][6]. Crafted from high-strength wear-resistant alloy steel[2][7], this injector undergoes 100% strict factory testing, precision performance calibration, and high-pressure leakage detection before shipment to fully comply with OEM specific-ations, ISO 9001 and IATF 16949 quality standards[1][6], ensuring consistent injection performance, exceptional durability, and perfect fitment with the engine’s fuel supply system. Adopting high-efficiency common rail injection technology and precision-machined multi-hole nozzle design, it achieves precise control of fuel injection volume, timing, and atomization, thereby optimizing engine power output, promoting full diesel combustion, reducing fuel consumption and harmful exhaust emissions, and delivering stable and reliable performance even under extreme high-load, high-temperature, and harsh working conditions. Its robust structure and anti-wear & anti-corrosion surface treatment make it highly adaptable to harsh environments such as dusty mining sites, high-temperature engine compartments, humid marine conditions, and high-intensity industrial workplaces. Widely applied in c-aterpillar 3412A-equipped equipment and 3500A series-powered generator sets, industrial machinery, marine vessels, and mining excavators[6], it provides steady power support, seamless fitment, and effectively minimizes equipment downtime, further reducing maintenance costs for global customers. 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$310 each, 6-19 pieces at US$290 each, ≥20 pieces at US$270 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.
