What is the required temperature rating for gasket and sealing materials in grease ducts?

The required temperature rating for gasket and sealing materials in grease ducts is 1500ºF. This high temperature rating is necessary because grease ducts often handle hot gases and can reach significant temperatures due to the nature of the cooking processes involved in commercial kitchens. The materials used in these applications must be capable of withstanding high temperatures to prevent degradation, maintain sealing, and ensure fire safety.

Using materials with insufficient temperature ratings can lead to failures such as leaks, which not only compromise the system's efficiency but can also create fire hazards. Therefore, selecting sealing materials that meet or exceed the 1500ºF requirement is essential for ensuring compliance with safety standards and maintaining the integrity of grease duct systems.
