An Aftercooler Gasket is a flexible seal of the connection between the aftercooler and the engine block. The aftercooler is a heat exchanger that cools the compressed air from the turbocharger before it enters the engine. It improves fuel economy and reduces emissions.Attributes:• Provides an effective seal between two or more mating surfaces, preventing leaks of fluids or gases.• Designed to withstand high temperatures and pressures, allowing them to maintain their sealing abilityApplications:An Aftercooler Gasket is used to provide a smooth surface for the coolant to flow over.
