S70225 is an AS568-225 red Silicone 70 Shore A O-Ring with an inside diameter of 1.859 in (47.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.137 in (54.28 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Silicone is valued for flexibility that holds at very low temperatures and very good compression set resistance across its range. This material stands up to extreme heat and cold, weathering, and dry heat. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Exposure to abrasive dynamic service or concentrated acids will shorten service life.
You will find this material specified across ovens and heated equipment, medical devices, and pharmaceutical manufacturing.
Stocked as S70225 and sold individually. Unit weight is approximately 2.27 g. 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.
