O-ring Temperature Chart

Rubber O-Ring Temperature Ranges

This chart provides the high and low-temperature ranges for popular rubber materials.  The closer you go to the limit of your rubber’s temperature range, the faster your material will degrade.  The O-rings' temperature range is determined by the base elastomer used. This chart depicts the maximum temperature range for each elastomer. The temperature range for a specific compound may not reach these maximum limits. Higher temperatures may be considered if exposure to the o-ring is short or intermittent.
