APG stocks the S70FDA121, an AS568-121 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 1.049 in (26.64 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.255 in (31.88 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Silicone is widely chosen for an exceptionally wide service temperature range, physiological inertness and low toxicity. The material holds up against ozone and UV exposure, extreme heat and cold, and dry heat. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where hydrocarbon fuels and oils or concentrated acids are present.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Common environments for this compound include pharmaceutical manufacturing, medical devices, and sanitary process lines.
