V75208 is an AS568-208 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 0.609 in (15.47 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.887 in (22.53 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The compound resists aromatic hydrocarbons, petroleum oils and fuels, and many acids. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving ketones and esters or low-molecular-weight organic acids call for a different compound.
Maintenance and OEM teams specify it across chemical processing, semiconductor equipment, and aerospace.
Reference part number V75208 when ordering; the item is sold individually. Unit weight is approximately 1.0819 g. Check the compound against your process media, pressure and temperature before committing to a design. 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.
