diesel fuel water separator element

112253220172 Diesel Fuel Filter Paper Core The 112253220172 paper filter core is a professional OEM standard fuel filter element designed for heavy-duty commercial trucks and industrial diesel engines. Produced strictly under IATF 16949 international automotive quality standards, this multi-layer pleated filter paper can effectively capture sediment, rust debris, carbon residue and other solid impurities in diesel fuel, while achieving excellent water separation performance to remove free moisture mixed in fuel supply lines. It delivers comprehensive protection for high-pressure fuel pumps, common rail injectors and precision fuel system parts, effectively preventing blockage, internal corrosion and insufficient engine power caused by impure fuel. The filter maintains stable performance under continuous engine vibration, frequent temperature changes and long-hour heavy-load working conditions, perfectly adapting to long-distance highway logistics, mining construction sites and harsh outdoor operating environments. Made with precise original mold sizing for direct plug-and-play replacement without cutting or modification, this filter core is widely purchased by global auto parts distributors, truck repair garages and fleet maintenance companies. It features reliable filtration stability, extended service life and outstanding cost performance, which greatly reduces fuel system breakdown risks and cuts regular vehicle maintenance expenses in the long run.  Product Material Description: Filter Medium: High-density reinforced composite cellulose filter paper, oil-resistant, large dirt holding capacity, excellent water separation efficiency and stable fuel permeability Inner & Outer Support Mesh: Galvanized perforated steel mesh, pressure-resistant, anti-deformation and rust-proof against long-term fuel erosion Upper & Lower End Caps: Thickened cold rolled steel with anti-corrosion coating, sturdy structure to resist bumping and vibration Sealing Gasket: High temperature resistant nitrile rubber, aging resistant and fully leakproof for long-term sealing Bonding Glue: Industrial high-strength hot melt adhesive, tight lamination without degumming under temperature fluctuation and continuous vibration
