This o-ring is supplied in AS568-177 blue Viton® (FKM) 75 Shore A measuring an inside diameter of 9.487 in (240.97 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.693 in (246.2 mm), catalogued under part number V75MD177. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Viton® (FKM) delivers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The compound resists aromatic hydrocarbons, petroleum oils and fuels, and many acids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C).
The compound 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 high-temperature process equipment, aerospace, and automotive fuel systems.
Stocked as V75MD177 and sold individually. Review your operating media and conditions against this specification before installation.
