This o-ring is supplied in AS568-152 brown Viton® (FKM) 75 Shore A built to an inside diameter of 3.237 in (82.22 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.443 in (87.45 mm), catalogued under part number VB75152. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The material holds up against many acids, chlorinated solvents, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) delivers outstanding high-temperature capability, excellent resistance to compression set and permeation. Continuous operating temperature is published at -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.
Maintenance and OEM teams specify it across semiconductor equipment, chemical processing, and high-temperature process equipment.
Order part number VB75152, sold individually. Unit weight is approximately 2.9488 g and nominal inside diameter is listed as 3 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. 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.
