Oil Filter LF3665
The Oil Filter LF3665 is a premium full-flow spin-on filtration unit designed to maintain internal engine cleanliness and stabilize lubrication loops in demanding fleet environments. Featuring an integrated bypass pressure valve with a precise opening profile of 98.07 kPa, it prevents engine oil starvation during cold starts or high-viscosity operational conditions. The heavy-duty steel outer casing is built to withstand rigorous pressure spikes, supporting a minimum hydrostatic burst strength of 1471.00 kPa. By utilizing advanced, heat-treated cellulose filtration media, this spin-on element continuously strips carbon soot, metal shavings, and organic sludge from the oil stream, significantly lowering bearing friction and expanding the operational lifespan of high-mileage utility trucks.
