The PAI differential cover gasket, measuring 6.5 " in outer diameter, 4.97 " in inner diameter, and 0.031 " in thickness, is specifically designed for Mack differentials. This gasket ensures optimal sealing performance with precision-crafted dimensions that effectively prevent leaks, maintaining a clean differential system. Its lightweight design contributes no added stress to the differential assembly. Additionally, it enhances the longevity of the differential by shielding internal components from contaminants. The resilient gasket material allows for simple maintenance requirements.
