V75458 is an AS568-458 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 14.475 in (367.67 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 15.025 in (381.64 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and industry benchmark where nitrile reaches its thermal limit. It resists many acids, aromatic hydrocarbons, and chlorinated solvents. 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 amines.

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

V75458 ships individually. Nominal inside diameter is listed as 14 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. 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.
