It replaces OEM numbers like Caterpillar 1S-4295, 7H-1558, and Mack 590GB321. This gasket fits engines such as the 3406E, C15, C12, and many others, utilizing a T6-style flange. It is typically replaced when the turbocharger is removed for service or if an exhaust leak develops at the flange, as leaks can cause power loss and soot buildup.
