Ordered as V75309, this is an AS568-309 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 0.412 in (10.46 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 0.832 in (21.13 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, Viton® (FKM) is valued for outstanding high-temperature capability and very low compression set at elevated temperature. The material holds up against chlorinated solvents, engine and transmission fluids, and aggressive chemicals. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.
Common environments for this compound include automotive fuel systems, high-temperature process equipment, and oil and gas.
Reference part number V75309 when ordering; the item is sold individually. Nominal inside diameter is listed as 7/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
