The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Source specification: FDA Compliant TO 21CFR Sec 177-2600, Metric O-RING.
The material holds up against extreme heat and cold, weathering, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is valued for excellent electrical insulating properties and an exceptionally wide service temperature range. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. It should not be specified for service in steam above its rated range or hydrocarbon fuels and oils.
