commercial truck fuel filter element

PU80201 Fuel Water Separator Filter Paper Core  The PU80201 paper filter core is a premium OEM-standard fuel water separator filter element designed for heavy-duty trucks, buses and engineering diesel engines, manufactured under strict IATF 16949 automotive quality standards. Built with professional hydrophobic multi-layer pleated filter paper, this element can efficiently capture rust particles, sediment, carbon deposits and solid contaminants in diesel fuel, while effectively separating free water and emulsified water inside the fuel pipeline. It provides full protection for high-pressure common rail fuel pumps and precision injectors, preventing injector clogging, fuel system corrosion, insufficient power and unstable engine operation caused by contaminated fuel. This filter maintains consistent performance under long-hour heavy-load driving, continuous road vibration and drastic temperature changes, perfectly suited for long-distance logistics transportation, mining construction sites and other harsh working environments. With precise original-size molding for direct plug-and-play replacement without modification, it is highly popular among global auto parts wholesalers, truck repair workshops and fleet maintenance companies. Featuring stable filtration performance, long service mileage and outstanding cost performance, it effectively reduces fuel system breakdown rates and cuts regular vehicle maintenance costs for fleet users.  Product Material Description: Filter Medium: 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: Thick cold-rolled steel with anti-corrosion coating, sturdy and shock-resistant against frequent vibration Sealing Gasket: High-temperature nitrile rubber ring, aging-resistant and fully leakproof for long-term sealing Bonding Adhesive: Industrial high-strength hot melt glue, tight lamination, no degumming under temperature fluctuation and continuous vibration
