That behavior comes from the compound itself: Silicone offers physiological inertness and low toxicity, very good compression set resistance across its range. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C).

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across food and beverage processing, pharmaceutical manufacturing, and ovens and heated equipment.
