Gasket
Mack

Engine gaskets are precision-formed seals designed to live at the interface of critical components under high heat and pressure. This gasket maintains a reliable barrier between mating surfaces to keep oil, coolant, and combustion byproducts from leaking or migrating into unintended areas. In Mack applications, a properly seated gasket contributes to compression integrity, oil control, and combustion chamber cleanliness, all of which influence power, efficiency, and emissions compliance. Material selection—whether composite or multi‑layer steel—with a carefully engineered sealing lip delivers compatibility with aggressive oil chemistries, thermal cycling, and mechanical loads encountered on long-haul and heavy‑haul duties. Proper installation demands clean, flat mating surfaces, correct torque, and the use of the appropriate sealant where specified by OEM guidelines. A fresh gasket reduces the risk of leaks at timing covers and valve covers, helps maintain proper compression, and minimizes the chance of cross‑contamination between fluids, thereby reducing downtime. It is an essential, mission‑critical consumable for fleets that demand consistent performance from their Mack powertrains. Source One Parts Center—your source for Mack parts.
