S70322 is an AS568-322 red Silicone 70 Shore A O-Ring measuring an inside diameter of 1.225 in (31.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.645 in (41.78 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.
Expect good resistance to many oxidizing chemicals, ozone and UV exposure, and dry heat. That behavior comes from the compound itself: Silicone offers excellent electrical insulating properties and an exceptionally wide service temperature range. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Exposure to hydrocarbon fuels and oils or steam above its rated range will shorten service life.
You will find this material specified across food and beverage processing, electronics and electrical enclosures, and sanitary process lines.
Stocked as S70322 and sold individually. Unit weight is approximately 3.645 g and nominal inside diameter is listed as 1 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
