Produced under strict ISO automotive quality standards, it maintains stable filtration efficiency under high fuel pressure and extreme temperature changes, serving as a reliable and cost-effective aftermarket maintenance spare part for logistics fleets, vehicle repair garages and construction machinery teams around the world.  Product Material Description: Filter Medium: High-density multi-layer composite glass fiber filter paper with uniform pore distribution, featuring stable filtration precision and outstanding dirt holding capacity; Outer Shell: Thickened high-strength cold-rolled steel housing with electrophoretic anti-rust coating, resistant to diesel corrosion, external impact and outdoor surface abrasion; Sealing Gasket: Premium nitrile rubber (NBR), with excellent oil resistance, wide high-low temperature resistance and long anti-aging performance to achieve complete leak-proof sealing; Internal Reinforced Galvanized Metal Skeleton: Firmly supports the filter element to prevent deformation or collapse under sustained high working fuel pressure; Hydrophobic Polymer Membrane: Specially formulated water-repellent material to realize highly efficient separation of water and diesel oil.

SGFF82005 F1171-061 Heavy Duty Diesel Fuel Water Separator Spin-On Filter SGFF82005 can be fully cross-replaced with F1171-061 spin-on fuel water separator filter, manufactured strictly according to heavy-duty vehicle industrial quality standards. This filter is widely applied to medium and heavy-duty diesel logistics trucks, engineering machinery, stationary diesel generator sets and various commercial diesel engines. During transportation and field operation, diesel fuel easily absorbs moisture and mixes with rust sediment, fine dust, sludge and tiny metal impurities. Once these contaminants enter the fuel supply system, they will cause fuel injector clogging, fuel pump abrasion, difficult cold start, unstable engine idle, insufficient acceleration power and obvious rise in fuel consumption. Equipped with multi-layer gradient composite filter medium and professional hydrophobic separation layer, this product can efficiently capture solid particles and separate free water mixed in diesel, delivering stable purified fuel to the engine fuel injection system. It comprehensively protects precision fuel system parts, maintains steady engine power under long-time heavy-load continuous operation, effectively reduces unexpected mechanical failures and subsequent maintenance expenses. Featuring stable performance under high fuel pressure and fluctuating temperature environments, it is a cost-effective and reliable aftermarket maintenance spare part for global transport fleets, construction teams and auto repair workshops.  Product Material Description: Filter Medium: High-density multi-layer composite glass fiber filter paper with uniform pore size, equipped with high filtration precision and excellent dirt holding capacity; Outer Housing: Thickened high-tensile cold rolled steel shell with full electrophoretic anti-rust coating, resistant to diesel corrosion, external impact and daily surface scratches; Sealing Gasket: Premium nitrile rubber (NBR), with outstanding oil resistance, high & low temperature resistance and long anti-aging life, realizing tight sealing without fuel leakage; Internal Reinforced Galvanized Metal Skeleton: Firmly supports filter paper to prevent element deformation or collapse under long-term high fuel working pressure; Hydrophobic Polymer Separation Membrane: Special water-repellent material to realize efficient oil-water separation effect.
