-457 BLACK FKM 75D O-RING

Part number V70457 is an AS568-457 black Viton® (FKM) 75 Shore A O-Ring with 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 seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists petroleum oils and fuels, aggressive chemicals, and many acids. That behavior comes from the compound itself: Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or ketones and esters call for a different compound.

Maintenance and OEM teams specify it across oil and gas, semiconductor equipment, and chemical processing.

V70457 ships individually. Unit weight is approximately 80.339 g and nominal inside diameter is listed as 14 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
