industrial engine diesel filter FF5688

GFF82004 FF5688 Heavy Duty Diesel Fuel Filter Water Separator SGFF82004 is fully cross interchangeable with FF5688 heavy-duty fuel water separator filter, manufactured to strict OEM standards for medium and heavy-duty diesel trucks, construction machinery and industrial diesel power units. Diesel fuel commonly contains free water, rust particles, sediment, sludge and fine solid contaminants generated during transportation and storage. Once these impurities enter the fuel system, they will scratch fuel injectors, wear fuel pumps, cause clogged fuel lines, rough idling, hard cold starting, insufficient power output and increased fuel consumption. This dual-purpose filter combines high-precision particle filtration and efficient water-oil separation performance with a multi-layer gradient filter structure. It steadily delivers purified diesel to the engine injection system, effectively protecting expensive precision fuel components, stabilizing engine power performance during long-time heavy-load operation, reducing unexpected mechanical failures and downtime. Built to withstand harsh outdoor working conditions with fluctuating pressure and temperature, this filter serves as a cost-effective and reliable aftermarket maintenance spare part for logistics fleets, construction equipment and commercial diesel vehicles worldwide.  Product Material Description: Filter Medium: High-density multi-layer composite glass fiber filter paper with uniform pore size, high filtration precision and superior dirt holding capacity; Outer Shell: Thickened high-tensile cold rolled steel housing with full electrophoretic anti-rust coating, resistant to diesel corrosion, physical impact and surface abrasion; Sealing Gasket: Premium nitrile rubber (NBR), featuring excellent oil resistance, wide temperature tolerance and long-term anti-aging property to achieve complete leakproof sealing; Internal Reinforced Galvanized Metal Skeleton: Firmly supports the filter element to prevent deformation or collapse under continuous high fuel pressure; Hydrophobic Polymer Separation Layer: Professional water-repellent material to realize efficient separation of water from diesel fuel.
