The range of temperature experienced during operation is an important factor when considering efficient sealing. It is particularly important to measure temperature in the immediate o-ring environment, not just the system temperature. You must also consider the length of exposure to any high temperature, whether it involves short bursts or long, sustained levels.

The temperature ranges for various o-ring materials are listed in the Material Selection Guide, as well as graphed in the Critical Operating Environmental Factors section. The Material Selection Guide allows users to enter a range to find the correct material.
