High Temp Glass Filled Nylon Wheels perform best in moist heat applications such as in smokehouses, moist heat bakery, and autoclave applications and around water and steam. Temperature Rating: Up to 425° F for 30 minutes MAXIMUM continuous operation. Then allow cooling to room temperature. If used above 425° For for more than 30 minutes of continuous operation it will reduce the life of the wheel. High-Temperature Glass-Filled Nylon wheels are not recommended for dry heat applications because once the moisture content of the wheel gets to zero, the wheel will shatter.
