APG stocks the V90469, an AS568-469 black Viton® (FKM) 90 Shore A O-Ring supplied with an inside diameter of 19.955 in (506.86 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.505 in (520.83 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
It resists aggressive chemicals, petroleum oils and fuels, and many acids. That behavior comes from the compound itself: Viton® (FKM) offers 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).
Maintenance and OEM teams specify it across oil and gas, chemical processing, and high-temperature process equipment.
Order part number V90469, sold individually. Unit weight is approximately 113.01 g and nominal inside diameter is listed as 20 inch. Review your operating media and conditions against this specification before installation. 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.
