LF3566 Fleetguard Spin-On Lube Filter 3966886 Heavy-Duty Engine Oil Filter
Product Description
LF3566 spin-on full-flow lube filter adopts high-capacity multi-layer composite filter media. It effectively traps metal wear particles, carbon sludge and oil oxidation residues inside heavy-duty engine lubricant to reduce internal engine abrasion. Thickened anti-corrosion carbon steel housing withstands sustained high oil pressure and severe full-load vibration. Oil-resistant nitrile rubber sealing ring eliminates fluid leakage risk. Matched to medium-heavy trucks, large excavators, agricultural heavy tractors and industrial generator sets, it stabilizes lubrication cleanliness and extends oil service intervals to cut maintenance expenditure.
