LF777 Fleetguard Spin-On Lube Filter 3889311 Engine Oil Filter
LF777 spin-on full-flow lube filter adopts multi-layer composite filter media with high dirt holding capacity. It efficiently captures metal wear debris, carbon sludge and oxidation residues in lubricating oil to reduce internal engine abrasion. Heavy-duty thickened carbon steel housing resists sustained high oil pressure and severe equipment vibration. Oil-resistant nitrile rubber sealing ring eliminates fluid leakage risk. Designed for medium-heavy trucks, mid-size excavators, agricultural tractors and stationary generator sets, it stabilizes lubrication cleanliness, extends oil service interval and lowers routine maintenance expenditure.
