Silicone is widely chosen for very good compression set resistance across its range, physiological inertness and low toxicity. The material carries a published service range of -80°F (-62.2°C) to 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 medical devices, ovens and heated equipment, and food and beverage processing.
