Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where hydrocarbon fuels and oils or concentrated acids are present.

This o-ring meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across sanitary process lines, pharmaceutical manufacturing, and food and beverage processing.
