FF5687 fuel filter

FF5687 P552200 FF2200 Heavy Duty Spin-On Diesel Fuel Filter The FF5687 fuel filter, cross-referenced with part numbers P552200 and FF2200, is a professional heavy-duty spin-on diesel fuel filter specially designed for Cummins heavy-duty diesel engines used in commercial trucks, excavators, loaders, agricultural equipment and industrial diesel generators. Serving as an essential core component of the engine fuel supply system, it precisely filters incoming diesel before fuel flows into high-pressure fuel pumps and precision fuel injectors. It efficiently captures solid contaminants such as rust particles, sand, carbon residue, sludge and colloidal impurities, greatly reducing abrasive damage to delicate fuel system components. Manufactured strictly under ISO/TS16949 automotive quality management standards, this filter delivers consistent high-efficiency filtration under continuous heavy-load operation, dusty mining sites, extreme high and low temperatures, as well as high-humidity working environments. It is a fully compatible aftermarket OEM replacement part, trusted to stabilize engine power, minimize unexpected downtime, and extend the service life of core engine fuel assemblies for long-haul trucks and engineering machinery worldwide.  Product Material Description: Outer Steel Housing: Thickened high-strength cold-rolled carbon steel shell with electrophoretic anti-rust and anti-corrosion coating. It features outstanding pressure resistance, impact resistance and diesel chemical resistance, which can withstand long-term rated fuel system pressure without expansion, cracking or fuel leakage, providing sturdy full protection for internal filter elements. Multi-Layer Gradient Filter Media: High-density composite wood pulp filter paper treated with reinforced resin, adopting deep pleated folding to maximize effective filtration area. The gradient density structure realizes progressive fine filtration, balancing excellent particle trapping efficiency and stable fuel flow to avoid insufficient oil supply under full engine load. High Temperature NBR Sealing Gasket: Industrial nitrile rubber sealing ring with superb resistance to diesel corrosion, heat and aging. It maintains reliable sealing elasticity within a working temperature range of -35℃ to 130℃, effectively preventing unfiltered fuel bypass and mounting joint leakage. Precision Machined Thread Base: CNC processed solid carbon steel thread base with standard accurate thread size, stable mechanical strength for easy spin-on installation and convenient routine disassembly during maintenance.
