-458 BLACK FKM 75D O-RING

V70458 is an AS568-458 black Viton® (FKM) 75 Shore A O-Ring built to 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 delivers dependable bidirectional sealing in a compact groove envelope.

It resists aromatic hydrocarbons, engine and transmission fluids, and many acids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving amines or hot water and steam call for a different compound.

Typical settings include semiconductor equipment, aerospace, and automotive fuel systems.

Order part number V70458, sold individually. Unit weight is approximately 83.058 g and nominal inside diameter is listed as 14 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
