APG stocks the V75317, an AS568-317 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 0.912 in (23.16 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.332 in (33.83 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
The material holds up against chlorinated solvents, aromatic hydrocarbons, and many acids. That behavior comes from the compound itself: Viton® (FKM) is valued for very low compression set at elevated temperature and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or low-molecular-weight organic acids.
Common environments for this compound include high-temperature process equipment, oil and gas, and semiconductor equipment.
This item is sold individually under part number V75317. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
