Product Specification

-
V75378 is an AS568-378 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 10.475 in (266.07 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.895 in (276.73 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists aromatic hydrocarbons, chlorinated solvents, and many acids. Viton® (FKM) offers outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where hot water and steam or low-molecular-weight organic acids are present.

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

Reference part number V75378 when ordering; the item is sold individually. Nominal inside diameter is listed as 10 1/2 inch. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
