Gasket
Mack

Designed to seal interfaces in the Mack powertrain and sub-systems, this gasket provides a reliable barrier against oil, coolant, fuel, and air leakage. The gasket's multi-layer or elastomer formulation is engineered to cope with high temperatures, chemical exposure, and constant vibration typical of long-haul operation. As a replacement part, it restores sealing integrity in critical junctions such as cylinder head-to-block connections, valve covers, oil pans, and water jackets, depending on its intended use. The seal distributes clamping load evenly, resisting creep and maintaining surface contact to prevent leaks that can degrade performance or invite contaminants. A proper seal supports maintaining compression, reduces the potential for overheating due to coolant loss, and helps preserve lubrication where oil leaks could cause bearing wear. In fleet service, replacing worn gaskets at scheduled intervals helps avoid unscheduled downtime, reduces the risk of hydro- or gas leaks, and contributes to safer, cleaner engine operation. Install with clean mating surfaces, inspect for flatness, and follow torque specs; use the correct sealant only when the service manual prescribes it. Source One Parts Center.
