FF63033 NN NanoNet Spin-On Diesel Fuel Filter FF63033 NN is a premium Fleetguard spin-on secondary fuel filter adopting advanced NanoNet nano fiber filtration technology, matched with OEM part number 1117101-A51-0000J. It is specially designed for Euro VI emission standard heavy-duty common rail diesel engines widely used on mainstream domestic heavy commercial trucks, logistics tractors and medium-sized construction machinery. Positioned in the rear section of the vehicle fuel supply system, it acts as the final precise protection barrier for high-pressure fuel pumps and precision fuel injectors. This filter efficiently intercepts ultra-fine rust particles, micro sand grains, carbon sludge, colloidal precipitates and tiny abrasive impurities mixed in diesel fuel, effectively preventing micro-scratches, clogging and early failure of precision fuel system components. Manufactured strictly in accordance with IATF 16949 automotive quality management system standards, it maintains stable ultra-precise filtration performance under long-distance highway transportation, dusty mountain mining routes, high-temperature tropical climates and frigid low-temperature northern working environments. As a fully compatible aftermarket OEM interchange filter, it greatly stabilizes engine power output, reduces unexpected vehicle downtime, and significantly extends the service life of expensive injectors and fuel pumps for heavy-duty fleet operation.
Product Material Description:
High-Strength Thickened Carbon Steel Outer Housing: Made of thick cold-rolled high tensile carbon steel with full electrophoretic anti-rust and anti-corrosion coating. It has excellent pressure resistance, impact resistance and diesel chemical corrosion resistance, which can withstand long-term rated working pressure of the fuel system without expansion, cracking or diesel leakage, providing comprehensive and stable external protection for the internal filter element structure.
NanoNet Nano Fiber Gradient Filter Media: Core NanoNet patented nano fiber composite filter material with deep dense pleated folding design to maximize the effective filtration area. The progressive gradient density fiber structure realizes staged ultra-fine filtration, achieving extremely high particle capture efficiency while keeping ultra-low flow resistance, far superior to traditional wood pulp filter paper in dirt holding capacity and long-cycle durability.
Industrial High-Temp NBR Sealing Gasket: Premium oil-resistant nitrile rubber sealing ring, resistant to long-term diesel soaking, high temperature aging and drastic temperature changes. It maintains stable sealing elasticity in the working temperature range of -35℃ ~ 130℃, thoroughly preventing bypass of unfiltered raw fuel and oil leakage at the installation joint.
Precision CNC Machined Thread Base: Solid carbon steel threaded base with standard precise thread tolerance, sturdy mechanical structure for convenient spin-on installation and quick disassembly during daily routine maintenance.
