York S1-7945-3011 Heat Exchanger Gasket Package

York S1-7945-3011 Heat Exchanger Gasket Package is a sealing component set designed to create a tight barrier between mating heat exchanger surfaces and adjoining furnace sections. When inflated between connected parts, the gaskets conform to the contact surfaces, limiting the escape of combustion gases and preventing unwanted air infiltration across sealed joints. Installed between the heat exchanger and its mating panels, the gasket package is used in HVAC systems requiring an airtight seal around the combustion assembly. It maintains separation between combustion and airflow passages and supports proper circulation through the intended airflow path.
