Gasket Material Temperature Ratings
The following table provides common temperature ratings for various gasket materials, which is critical for selecting the appropriate seal for specific operating conditions.
Gasket Material | Temperature Rating(°F) | Temperature Rating(°C) |
|---|---|---|
| EPDM | -30 to 230 | -34 to 110 |
| Nitrile | -20 to 180 | -29 to 82 |
| Neoprene | 30 to 180 | -1 to 82 |
| Fluoroelastomer | 20 to 300 | -7 to 149 |
| Silicone | -30 to 350 | -34 to 177 |

Selecting a gasket material outside its rated temperature range can lead to loss of elasticity, hardening, degradation, and ultimately, seal failure. The temperature ratings represent continuous operating limits; short-term excursions may be possible but will reduce service life.
