APG stocks the S70245, an AS568-245 red Silicone 70 Shore A O-Ring measuring an inside diameter of 4.359 in (110.72 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.637 in (117.78 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
Silicone is specified here for physiological inertness and low toxicity, very good compression set resistance across its range. The material holds up against dry heat, weathering, and ozone and UV exposure. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Exposure to abrasive dynamic service or hydrocarbon fuels and oils will shorten service life.
You will find this material specified across electronics and electrical enclosures, sanitary process lines, and medical devices.
