FF5688 fuel filter

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.

FF5688 SGL2000104 FUEL Filter  This spin-on diesel fuel filter cross-references part numbers FF5688, SGL2000104, fully interchangeable with Baldwin BF9844, Donaldson R010019 and OEM No. G58001105140C, 23390-E0020. Manufactured strictly per IATF 16949 automotive quality standards, it adopts high-efficiency multi-layer composite cellulose filter media with professional spin-on integrated housing structure. Designed for heavy-duty diesel engines of commercial trucks, passenger buses and construction excavators, it precisely traps solid particles, rust, colloids and separates free water from diesel fuel. It delivers stable fuel flow with low pressure drop under heavy-load working conditions, perfectly protecting high-pressure fuel pumps and injectors, extending engine overhaul cycles, and serving as a cost-effective direct OEM replacement spare part for global aftermarket maintenance. Material Description: The filter core adopts imported high-density wood pulp cellulose mixed with fine glass fiber composite filter paper, formed by deep pleating technology to maximize the effective filtering area. The filter paper features excellent oil resistance, hydrolysis resistance and dimensional stability, and will not soften, expand or deform after long-time immersion in diesel, biodiesel and low-quality fuel. The outer shell is made of thickened cold-rolled steel plate with anti-rust electrophoretic coating inside and outside, featuring strong pressure resistance and corrosion resistance. The sealing rubber ring is crafted from high-grade NBR nitrile rubber, resistant to high temperature, oil aging and cold brittleness, which can maintain stable elasticity for a long time in variable temperature working environments. The internal central support tube uses perforated galvanized iron material, which firmly supports the filter element to avoid collapse under high fuel pressure, ensuring stable filtration performance in the whole service cycle.
