APG stocks the VB90212, an AS568-212 brown Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 0.859 in (21.82 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.137 in (28.88 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
The compound resists petroleum oils and fuels, aggressive chemicals, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers excellent resistance to compression set and permeation, very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).
It sees regular use in high-temperature process equipment, aerospace, and semiconductor equipment.
Order part number VB90212, sold individually. Unit weight is approximately 1.7415 g and nominal inside diameter is listed as 7/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
