1. High-Strength Alloy Forged Body
   The injector main body adopts high-precision alloy steel integral forging, outstanding resistance to high temperature and high fuel pressure. Stable long-term full-load operation performance under construction and mining harsh environments, no deformation or internal fuel leakage.
2. Precision Multi-Stage Injection Nozzle Assembly
   Equipped with micro multi-hole precision nozzle assembly, multi-stage variable injection control structure. Each injector completes strict flow, atomization and dynamic balance testing before delivery, realize uniform fuel atomization, raise combustion efficiency, reduce black smoke and nitrogen oxide emissions.
3. 100% OEM Size & Calibration Standard
   Fully comply with CAT original machining and calibration standards, internal fuel channel size and electromagnetic control parameters consistent with OEM injectors. Direct plug-and-play replacement without ECU parameter modification, perfect matching CAT 3126B engine.
4. Multi-Layer High Pressure Sealing System
   Multi-layer composite fluorine rubber sealing rings installed on all oil circuit joints, with strong oil resistance, high temperature resistance and anti-aging performance. Effectively block internal and external fuel leakage, extend injector service cycle and lower maintenance frequency.
5. Optimized Power & Fuel Economy Performance
   Accurate control of injection timing and fuel delivery volume, effectively solve engine insufficient power, unstable speed, excessive fuel consumption and exhaust black smoke faults. Keep original power output of 3126B engine, reduce cylinder liner and piston wear.

Delivery: Multiple global shipping channels including air and sea freight. Each injector is individually oil-sealed with anti-collision foam packaging, complete inspection reports and traceable tracking number.

All products pass hydraulic pressure and atomization test before shipment.

Import duties, local consumption taxes and extra handling fees are not included in quoted price and freight. Buyers shall bear all relevant fees in accordance with local customs regulations.

This heavy-duty diesel fuel injector is specially designed for CAT 3126B engine with OEM part number 183-0691, widely used in CAT 325C, 330C excavators and articulated mining trucks. It adopts alloy forged body, precision multi-stage injection nozzle and factory original calibration data, fully reaches OEM matching standard. It is the core replacement spare part for engine overhaul, effectively reduce equipment downtime and long-term maintenance costs.
