Compatible with Bosch CRIN 120 Series Heavy-Duty Common Rail Injector 0445120231 – For Komatsu HD785 / Hitachi EX3600

The injector 0445120231, which is compatible with Bosch CRIN 120 series, is suitable for large mining equipment such as Komatsu HD785 and Hitachi EX3600. It meets Euro III emission requirements and is adapted to heavy - load and high - dust working environments.

The injector adopts a strengthened dust - proof sealing structure, combined with the hydraulic lapping process of the spray holes. Under the condition of particle wear, its service life can be increased by up to 50%. The valve seat, a key component, is made of vanadium alloy material and undergoes precise heat treatment, improving its toughness against thermal shock and mechanical fatigue.

These improvements make it more suitable for high - dust and high - intensity continuous - operation scenarios such as mining areas, taking into account both durability and stable injection performance.
