APG stocks the V75MD049, an AS568-049 blue Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 4.989 in (126.72 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 5.129 in (130.28 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. The material holds up against aromatic hydrocarbons, engine and transmission fluids, and petroleum oils and fuels. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or hot water and steam call for a different compound.
This o-ring 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, chemical processing, and automotive fuel systems.
V75MD049 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
