-247 BLACK FKM 75D O-RING

This o-ring is supplied in AS568-247 black Viton® (FKM) 75 Shore A measuring an inside diameter of 4.609 in (117.07 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.887 in (124.13 mm), catalogued under part number V70247. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. The material holds up against petroleum oils and fuels, many acids, and aromatic hydrocarbons. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and high-temperature process equipment.
