O-ring Temperature Chart

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.
