F0125-004 fuel filter

F0125-004 Spin-On Diesel Fuel Filter OEM K6200-1105140KS1 F0125-004 is a professional spin-on secondary diesel fuel filter, fully cross-referenced with OEM part number K6200-1105140KS1 and interchangeable with MF30485, specially customized for Yuchai 6K series Euro VI common rail heavy-duty diesel engines widely equipped on JAC heavy trucks, bulk cargo vehicles, tractor units and medium construction machinery. Installed on the rear fuel pipeline before high-pressure fuel pumps and precision fuel injectors, it serves as the final precision protection barrier for the engine fuel system. This filter efficiently captures rust particles, fine sand, carbon residue, colloidal sludge and tiny abrasive impurities mixed in diesel fuel, effectively preventing micro-scratches, injector clogging and premature fuel pump damage. Manufactured strictly under IATF 16949 automotive quality management standards, it delivers stable long-cycle filtration performance during long-distance highway haulage, dusty mining routes, high-temperature tropical climates and frigid low-temperature northern working environments. As a perfect aftermarket OEM direct replacement filter, it stabilizes sustained engine power output, reduces unexpected vehicle downtime, and greatly extends the service life of expensive precision fuel system assemblies for heavy-duty fleets.  Product Material Description: High-Strength Thickened Carbon Steel Housing: Made of thick cold-rolled high tensile carbon steel with full electrophoretic anti-rust and anti-corrosion coating. Standard dimension Φ110×243mm, thread specification M32×1.5-6H. It features outstanding pressure resistance and impact resistance, capable of enduring long-term rated fuel system working pressure without expansion, cracking or diesel leakage, providing comprehensive stable outer protection for internal filter media. Multi-Layer Gradient Composite Filter Media: High-density resin-impregnated wood pulp filter paper with deep dense pleated folding design to maximize effective filtration area. The progressive gradient density structure realizes staged precise fine filtration, balances excellent particle trapping efficiency and ultra-low flow resistance, ensuring sufficient steady fuel supply even under full engine rated load. Industrial Grade NBR Nitrile Rubber Seal: Premium oil-proof high-temperature nitrile rubber sealing gasket, resistant to long-term diesel soaking, thermal aging and drastic temperature fluctuations. It maintains stable sealing elasticity within -35℃ ~ 130℃ working temperature range, completely preventing bypass of unfiltered raw fuel and oil leakage at the mounting joint. Precision CNC Thread Base: Solid carbon steel threaded base with standard M32×1.5 internal thread processed by CNC machining, accurate thread tolerance and rigid structural strength for convenient spin-on installation and quick disassembly during daily routine maintenance.
