-419 BLACK FKM 75D O-RING

APG stocks the V75419, an AS568-419 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 3.725 in (94.62 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.275 in (108.59 mm). An o-ring 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 compound resists many acids, petroleum oils and fuels, and engine and transmission fluids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to amines or hot water and steam will shorten service life.

You will find this material specified across oil and gas, semiconductor equipment, and chemical processing.

Stocked as V75419 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
