APG stocks the V75908, an AS568-908 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 0.644 in (16.36 mm), a cross section of 0.087 in (2.21 mm), and an outside diameter of 0.818 in (20.78 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The material holds up against aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is valued for outstanding high-temperature capability and very low compression set at elevated temperature. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or amines.
It sees regular use in aerospace, chemical processing, and automotive fuel systems.
This item is sold individually under part number V75908. Nominal inside diameter is listed as 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
