L6500-1105140 fuel filter

L6500-1105140 P502466 Spin-On 2 Micron Diesel Fuel Filter L6500-1105140 is the official OEM part number for Yuchai & Sinotruk heavy-duty engines, fully interchangeable with Donaldson standard part P502466, a premium spin-on secondary diesel fuel filter with professional 2μm ultra-precision filtration performance. Designed for mainstream Weichai, Yuchai, Sinotruk MC series heavy-duty truck engines and Kobelco SK series excavator diesel power systems, it acts as the core precision protection component of the fuel supply pipeline before high-pressure fuel pumps and common rail injectors. This filter efficiently captures micro solid contaminants including rust grit, fine sand, carbon sludge, colloidal deposits and tiny abrasive particles inside diesel fuel, effectively preventing injector scoring, clogging and fuel pump premature damage. Manufactured strictly following IATF 16949 international automotive quality certification standards, it passes ISO 4548-12 professional filtration testing, delivering stable consistent performance during long-distance highway haulage, dusty mining construction sites, high-temperature tropical areas and frigid low-temperature northern operating environments. As a perfect cross aftermarket replacement for original L6500-1105140 and Donaldson P502466 filters, it stabilizes continuous engine power output, cuts unexpected vehicle downtime, and significantly extends the service life of expensive precision fuel system assemblies for heavy commercial fleets and engineering machinery.  Product Material Description: Heavy-Duty Thickened Carbon Steel Housing: Adopts thick cold-rolled high tensile carbon steel shell with full electrophoretic anti-rust and anti-corrosion coating. Overall dimension: OD 108mm, Height 210mm, standard thread specification 1"-14UNF-2B. It withstands maximum working pressure up to 6.9bar, featuring excellent pressure resistance and impact resistance, no expansion, cracking or diesel leakage under long-term operation, offering full physical protection for internal filter media. High-Density Gradient Cellulose Filter Media: Premium resin-impregnated multi-layer cellulose filter paper with deep dense pleated folding design to maximize effective filtration area. Progressive gradient density structure realizes staged fine filtration, achieving stable 2μm particle capture efficiency, balancing outstanding contaminant holding capacity and ultra-low flow resistance to guarantee smooth fuel supply under full engine rated load. Industrial Grade NBR Nitrile Rubber Seal Ring: High temperature & oil resistant nitrile rubber gasket, resistant to long-term diesel erosion, thermal aging and drastic temperature fluctuation. It maintains stable sealing elasticity within working temperature range of -35℃ ~ 130℃, completely preventing unfiltered fuel bypass and mounting joint oil leakage. Precision CNC Machined Thread Base: Solid carbon steel threaded base with accurate thread tolerance and rigid structural strength, supporting fast spin-on installation and convenient disassembly during routine maintenance.
