This o-ring is supplied in AS568-116 blue Viton® (FKM) 75 Shore A built to an inside diameter of 0.737 in (18.72 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.943 in (23.95 mm), catalogued under part number V75MD116. It remains the most cost-effective sealing element available for pressurized assemblies.
This material stands up to many acids, chlorinated solvents, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) offers long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.
This item meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. It sees regular use in semiconductor equipment, aerospace, and oil and gas.
Reference part number V75MD116 when ordering; the item is sold individually. Nominal inside diameter is listed as 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
