This o-ring is supplied in AS568-387 blue Viton® (FKM) 75 Shore A built to an inside diameter of 17.955 in (456.06 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 18.375 in (466.73 mm), catalogued under part number V75MD387. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Viton® (FKM) offers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The material holds up against many acids, petroleum oils and fuels, and chlorinated solvents. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or ketones and esters will shorten service life.
This item meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. It sees regular use in aerospace, automotive fuel systems, and semiconductor equipment.
V75MD387 ships individually. Nominal inside diameter is listed as 18 inch. Check the compound against your process media, pressure and temperature before committing to a design.
