4676385 fuel filter

4676385 OEM Fuel Filter Replacement Element Cross 4649267 PF7983 P502463 4676385 is a professional OEM-grade cartridge fuel filter specially developed for Hitachi ZAXIS excavators, wheel loaders and engineering machinery equipped with Isuzu 4HK1 and AH6HK1 diesel engines, cross compatible with part numbers 4649267, Baldwin PF7983, Donaldson P502463 and Fleetguard FF5786. As the key precision filtration component of the engineering vehicle fuel supply system, this filter efficiently captures rust particles, sand, sludge, carbon sediment and emulsified free moisture mixed in diesel fuel before fuel flows into high-pressure fuel pumps and precision injectors. It effectively prevents abrasive wear, internal blockage and electrochemical corrosion of delicate fuel system core parts. Manufactured strictly according to original OEM dimension standards and IATF16949 automotive quality specifications, it stabilizes fuel delivery pressure remarkably, promotes complete diesel combustion, boosts engine power output, reduces fuel consumption and black smoke emission under continuous heavy-load construction operation. Widely applied to Hitachi ZAXIS full series excavators, ZW series wheel loaders and matching stationary diesel generator sets. Every finished product undergoes strict burst pressure, water separation efficiency and durability testing. We provide sufficient spot stock, customizable private label packaging and a 12-month quality warranty, which is a reliable stocking spare part choice for global construction machinery parts distributors, repair service centers and engineering fleet maintenance teams.  Product Material Description: Filter Media: Multi-layer high-density composite wood pulp filter paper with dense uniform pleats, featuring stable micron filtration precision, excellent water repellency and ultra-large dirt holding capacity for long continuous working hours. Sealing O-Ring: Premium NBR nitrile butadiene rubber gasket included, resistant to diesel corrosion, high temperature and low-temperature aging hardening, realizing full tight sealing to completely eliminate fuel leakage at assembly joints. Upper & Lower End Caps: High-strength reinforced integrated engineering plastic end covers, rigid structure that resists deformation and cracking under sustained high fuel pressure impact. Internal Support Skeleton: Perforated galvanized steel inner framework, firmly supports the pleated filter paper to avoid collapse and distortion caused by instantaneous strong fuel flow.
