Made from durable yet slightly compressive air-filled PVC and available in two thicknesses, these gaskets are ideal for mating dampers to trunks, bulkheads, fans or airflow diverters to provide galvanic isolation as well as a complete seal and even seating. Round damper isolation gaskets are available in sizes up to 48 inches in diameter. Rectangular damper gaskets are available in sizes up to 48 X 96 inches.
