APG stocks the V90452, an AS568-452 black Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 11.475 in (291.47 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 12.025 in (305.44 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. It resists petroleum oils and fuels, aggressive chemicals, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life.
Maintenance and OEM teams specify it across semiconductor equipment, chemical processing, and high-temperature process equipment.
Reference part number V90452 when ordering; the item is sold individually. Unit weight is approximately 65.1953 g and nominal inside diameter is listed as 11 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design. 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.
