Product Specification

-
V75431 is an AS568-431 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 5.225 in (132.72 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.775 in (146.69 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists aromatic hydrocarbons, petroleum oils and fuels, and aggressive chemicals.

Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or low-molecular-weight organic acids call for a different compound.

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

This item is sold individually under part number V75431. Unit weight is approximately 31.1925 g and nominal inside diameter is listed as 5 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
