-019 BLACK FKM 75D O-RING

Ordered as V70019, this is an AS568-019 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 0.801 in (20.35 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.941 in (23.9 mm). The 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 many acids, aromatic hydrocarbons, and chlorinated solvents. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or amines will shorten service life.

Maintenance and OEM teams specify it across aerospace, automotive fuel systems, and semiconductor equipment.
