-155 BLACK CHEMOURS VITON 75D O-RING

VITON75155 is an AS568-155 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 3.987 in (101.27 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.193 in (106.5 mm). In service, this 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 compound resists chlorinated solvents, aromatic hydrocarbons, and engine and transmission fluids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life.

You will find this material specified across chemical processing, aerospace, and high-temperature process equipment.

VITON75155 ships individually. Unit weight is approximately 3.261 g and nominal inside diameter is listed as 4 inch.
