light commercial vehicle diesel filter

FF185 TP877 Spin-On Diesel Fuel Water Separator Filter FF185 fuel filter with cross reference part number TP877 is a high-efficiency spin-on integrated fuel and water separator specially developed for Yunnei common rail diesel engines equipped on light commercial vehicles. Positioned on the front section of the vehicle fuel delivery system, it acts as critical purification equipment to process diesel before fuel enters high-pressure oil pumps and precision fuel injectors. This filter efficiently captures solid impurities such as fine sand, rust particles, carbon deposits and colloidal sludge inside diesel oil, while rapidly separating free water and suspended moisture droplets. Manufactured strictly following ISO/TS16949 international automotive quality certification standards, it is fully compatible with Euro IV, Euro V and Euro VI emission standard Yunnei engines. It maintains stable filtration performance during long-distance highway logistics, urban daily delivery, dusty construction roads, high-humidity coastal areas and low-temperature cold weather. As a reliable aftermarket replacement component, it effectively protects precision fuel system parts, reduces abnormal wear and clogging failures, and guarantees stable engine power output for light trucks, pickups and small engineering machinery in daily operation.  Product Material Description: Outer Carbon Steel Housing: Adopts thickened cold-rolled carbon steel with full electrophoretic anti-rust paint treatment. It possesses outstanding pressure resistance, impact resistance and diesel corrosion resistance, which can withstand long-term normal working pressure of fuel systems without expansion, cracking or oil leakage, providing solid external protection for internal filter elements. Gradient Composite Filter Paper: Multi-layer high-density wood pulp filter media impregnated with hydrophobic resin, manufactured with deep dense pleating technology to maximize the effective filtration area. The gradient density structure realizes staged fine filtration and strong hydrophobic performance, balancing top-tier filtration precision and steady fuel flow rate without oil supply shortage. NBR Sealing Gasket: Premium nitrile rubber sealing ring with excellent resistance to diesel erosion, high temperature and aging. It maintains stable sealing elasticity within the temperature range of -35℃ to 125℃, effectively preventing bypass of unfiltered fuel and leakage at the installation joint. Precision CNC Thread Base: Machined solid carbon steel threaded base with standard thread specifications and precise dimensional tolerance. The sturdy structure supports convenient spin-on installation and quick disassembly during routine maintenance.
