Continuous operating temperature is published at -75°F (-59.4°C) to 400°F (204.4°C). It should not be specified for service in installation over sharp edges or tight-radius dynamic flexing.
Typical settings include cryogenic and high-temperature equipment, pharmaceutical manufacturing, and chemical processing.
