Dongfeng ISZ13 ISZ15 engine fuel filter

1125030-H02F0 OEM Diesel Fuel Filter Element Cross 1125030-H02B0 1125030-H02F0 is an OEM standard high-efficiency fuel water separator filter, interchangeable with part number 1125030-H02B0, professionally developed for Dongfeng ISZ13 and ISZ15 series Euro 5 / Euro 6 diesel engines fitted on Dongfeng Kinland Flagship KX, KL, KR and Tianlong heavy-duty trucks. As the core precision purification component of the high-pressure common rail fuel system, this filter adopts advanced coalescing separation technology to efficiently capture rust particles, sand, sludge, carbon sediment and emulsified free moisture contained in diesel fuel. It thoroughly cleans fuel before delivery to high-pressure fuel pumps and precision fuel injectors, effectively preventing abrasive wear, internal blockage and electrochemical corrosion of delicate fuel system core components. Manufactured strictly according to original OEM dimensional specifications and IATF16949 automotive quality management standards, this filter stabilizes fuel rail pressure consistently, promotes full combustion of diesel, boosts engine power output, reduces fuel consumption and black smoke emissions during long-distance heavy-load transportation. Widely applied to long-haul tractors, container trucks, dump trucks and logistics heavy vehicles of Dongfeng flagship series. All finished products pass strict burst pressure, water separation efficiency and long-term aging durability tests. We provide sufficient spot inventory, neutral packaging & private label customization and a 12-month quality warranty, which is a stable and cost-effective spare part choice for global heavy truck auto parts wholesalers, professional repair service centers and large logistics fleet maintenance teams.  Product Material Description: Filter Media: Multi-layer high-density gradient composite wood pulp filter paper with dense uniform pleated structure, featuring stable micron filtration precision, excellent hydrophobic demulsification performance and ultra-large dirt holding capacity for continuous long-hour heavy-duty operation. Sealing Rubber Gasket: Premium NBR nitrile butadiene rubber sealing ring, resistant to diesel corrosion, high temperature and low-temperature aging hardening, realizing complete tight sealing to fully eliminate fuel leakage at assembly joints. Upper & Lower End Caps: High-strength thickened engineering plastic end covers with integrated injection molding, rigid structure that resists deformation and cracking under sustained high fuel working pressure impact. Internal Support Skeleton: Reinforced perforated plastic central framework, which firmly supports the pleated filter media to avoid collapse and distortion caused by instantaneous strong fuel flow pressure.
