The Delfield 1702473 Refrigerator Door Gasket helps maintain a tight seal to preserve consistent cooling and improve energy efficiency. Designed with a 7/16" magnetic strip and a 15/16" base, this gasket fits securely into compatible refrigerator doors to prevent cold air from escaping and warm air from entering. It works by creating a firm magnetic seal when the door is closed, helping the unit maintain stable internal temperatures during daily use. Its dependable sealing performance helps reduce strain on the refrigeration system, minimize energy loss, and support proper food storage conditions in commercial kitchen environments.
