Lube Filter
Mack

Engine oil filtration is a critical line of defense against abrasive wear in heavy duty Mack applications. This lube filter uses a high capacity filtration media to trap particulates that can erode bearings, journals, and piston surfaces. An anti drain back valve keeps oil in the filter housing when the engine is shut down, delivering immediate lubrication on restart and protecting the pump from cavitation. A bypass valve provides continued lubrication in case the filter becomes severely clogged, preventing sudden oil starvation. The cartridge is designed for easy removal with common filter wrenches and features a precise gasket seal to prevent leaks under hydraulic pressure. Filtration performance contributes to longer oil life, reduced soot contamination, and stable oil pressure under heavy load. Replacing the filter at recommended intervals is a simple, cost effective way to extend engine life and avoid costly repairs caused by contaminated oil. This part is engineered for rugged Mack applications, delivering reliable filtration in dusty, cold, or high mile age service. Brought to you by Source One Parts Center.
