Part number V75319 is an AS568-319 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 1.037 in (26.34 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.457 in (37.01 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Viton® (FKM) is known for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The compound resists many acids, engine and transmission fluids, and petroleum oils and fuels. 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 ketones and esters or amines are present.

You will find this material specified across automotive fuel systems, aerospace, and high-temperature process equipment.
