-451 BLACK FKM 75D O-RING

V75451 is an AS568-451 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 10.975 in (278.77 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 11.525 in (292.74 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to aromatic hydrocarbons, petroleum oils and fuels, and aggressive chemicals. Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in ketones and esters or low-molecular-weight organic acids.

It sees regular use in chemical processing, high-temperature process equipment, and semiconductor equipment.

V75451 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. 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.
