"O-ring materials may be subjected to high or low temperatures, chemical attack, vibration, abrasion, and movement. Elastomers are selected according to the situation. There are O-ring materials which can tolerate temperatures as low as −328.0 °F (−200 °C) or as high as 482 °F (250 °C). At the low end, nearly all engineering materials become rigid and fail to seal; at the high end, the materials often burn or decompose. Chemical attack can degrade the … " - O ring expansion
