Details & Benefits

Product Name

c-aterpillar Fuel Injector Nozzle

Part Number (General Number)

0R-3420

Ultra-Fine Atomization

5-hole precision-drilled orifice with 142μm diameter ensures uniform and fine fuel droplets, optimizing fuel-air mixing, improving combustion efficiency by up to 27%, and reducing fuel consumption effectively for heavy-duty 3208/3406 series engines[2][3][5].

High-Pressure Durability

Engineered to withstand 11.0 MPa operating pressure, with heat-treated alloy steel construction (HRC56-58) that resists deformation and leakage under high-pressure conditions, ensuring stable performance in long-term heavy-load operations for 3208/3406-powered c-aterpillar equipment[5][3].

Anti-Clogging & Anti-Wear

Smooth orifice surface and wear-resistant coating prevent dust, carbon deposits, and impurities from clogging, extending the nozzle's service life in dusty, harsh working environments common in construction and mining applic-ations, suitable for the diverse operating conditions of 3208/3406-powered equipment[2][3].

OEM Compatibility

Direct-fit design strictly matches c-aterpillar OEM specific-ations, requiring no modific-ations during installation, ensuring perfect integration with the injector and fuel system for 3208/3406B/3406C/3406E series engines, and can replace old part numbers 4W7016, 0R1743, and R0R3420[1][2][3].
