Product Overview

The Dometic / Atwood 32172 Furnace Gasket is a genuine OEM replacement gasket designed for use with Atwood furnaces equipped with DSI (Direct Spark Ignition) systems.

This gasket provides a secure seal between key furnace components, helping maintain proper combustion airflow and preventing air leakage within the burner chamber area. Maintaining an intact seal is critical for efficient ignition, correct flame performance, and safe furnace operation.
