High Temp O-Ring & Low Temp O-Ring Ranges

High Temp O-Ring & Low Temp O-Ring Ranges for Common Materials

Temperature ranges are recommendations with a margin of safety when setting the general operating temperature of common elastomers.

Maximum temperature recommendations are based on long term functional service. If it is subjected to this temperature continuously, it should perform reliably for 1,000 hours. Since the top limit for any compound varies with the medium, the high-temperature limit for many compounds is shown as a range rather than a single figure.

It is important that you analyze all aspects of your application. Due to the variety of operating conditions and applications for these products or systems, the user, through his or her own analysis and testing, is solely responsible for making the final selection of the products and systems.
