Ordered as V70468, this is an AS568-468 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 19.455 in (494.16 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.005 in (508.13 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
The compound resists many acids, petroleum oils and fuels, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for very low compression set at elevated temperature, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to amines or low-molecular-weight organic acids will shorten service life.
Maintenance and OEM teams specify it across chemical processing, oil and gas, and automotive fuel systems.
This item is sold individually under part number V70468. Unit weight is approximately 111.76 g. Application requirements vary, so validate compatibility with your process conditions prior to 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.
