APG stocks the S70234, an AS568-234 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 2.984 in (75.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.262 in (82.85 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The material holds up against ozone and UV exposure, extreme heat and cold, and dry heat. Silicone is widely chosen for very good compression set resistance across its range and excellent electrical insulating properties. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where concentrated acids or hydrocarbon fuels and oils are present.
You will find this material specified across pharmaceutical manufacturing, electronics and electrical enclosures, and sanitary process lines.
Stocked as S70234 and sold individually. Unit weight is approximately 3.419 g and nominal inside diameter is listed as 3 inch. Review your operating media and conditions against this specification before installation.
