-457 BLACK FKM 90D O-RING

Part number V90457 is an AS568-457 black Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 13.975 in (354.97 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 14.525 in (368.94 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to aggressive chemicals, aromatic hydrocarbons, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is known for excellent resistance to compression set and permeation, outstanding high-temperature capability. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

It sees regular use in semiconductor equipment, aerospace, and oil and gas.

V90457 ships individually. Unit weight is approximately 79.0661 g and nominal inside diameter is listed as 14 inch. 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.
