Depending on the temperature of the material at which it is worked, it is from -60°C to + 200°C.
Depending on the working environment, O-ring products of different materials are used. For example, when working in an oily environment (oils and grease), NBR rubber O-rings are suitable; when working with gasoline and organic solvents, FPM fluoro rubber is used, and in water and steam environments, EPDM rubber O-rings are recommended.
