fleet commercial truck fuel filter element

FS20021 Diesel Fuel Water Separator Filter Paper Core FS20021 paper filter core is a professional OEM-standard fuel water separator filter specially designed for modern heavy-duty commercial trucks, construction machinery and large diesel engines, manufactured strictly following IATF 16949 automotive quality management system. The advanced multi-layer composite pleated filter medium can efficiently filter rust particles, sediment, carbon residue and solid impurities mixed in diesel fuel, meanwhile efficiently separating free water and emulsified moisture inside the fuel circuit. It provides full protection for high-pressure common rail fuel pumps and precision injectors, effectively avoiding injector blockage, internal component corrosion, insufficient power and unstable engine operation caused by contaminated fuel. This filter maintains stable filtration performance under long-time heavy-load operation, continuous vibration and extreme temperature changes, perfectly adapting to long-distance logistics transportation, mining sites, construction projects and other harsh working conditions. With precise original size molding for direct plug-and-play replacement without modification, this filter is highly favored by global auto parts wholesalers, truck repair garages and fleet maintenance companies. It features stable filtration performance, long service mileage and excellent cost performance, which can effectively reduce fuel system failure frequency and cut overall vehicle maintenance costs for fleet users.  Product Material Description: Filter Medium: Imported high-density hydrophobic reinforced cellulose filter paper, excellent water repellency, large dirt holding capacity and stable fuel permeability Inner & Outer Support Mesh: Galvanized perforated steel mesh, pressure-resistant, anti-deformation and rust-proof against long-term diesel erosion Upper & Lower End Caps: Thickened cold rolled steel with anti-corrosion coating, sturdy structure resistant to vibration and impact Sealing Gasket: High-temperature resistant nitrile rubber ring, aging-resistant and complete leakproof sealing Bonding Adhesive: High-strength industrial hot melt glue, tight permanent lamination, no degumming under temperature fluctuation and persistent vibration
