The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to many oxidizing chemicals, weathering, and extreme heat and cold. That behavior comes from the compound itself: Silicone offers physiological inertness and low toxicity, an exceptionally wide service temperature range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). It should not be specified for service in abrasive dynamic service or steam above its rated range.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in pharmaceutical manufacturing, food and beverage processing, and medical devices.
