APG stocks the V75448, an AS568-448 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 9.475 in (240.67 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 10.025 in (254.64 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Expect good resistance to aggressive chemicals, many acids, and engine and transmission fluids. Viton® (FKM) is known for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or ketones and esters call for a different compound.
Common environments for this compound include automotive fuel systems, aerospace, and high-temperature process equipment.
V75448 ships individually. Unit weight is approximately 54.9 g and nominal inside diameter is listed as 9 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. Not finding the exact configuration you need?
