-429 BROWN FKM 75D O-RING

Part number VB75429 is an AS568-429 brown Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 4.975 in (126.37 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.525 in (140.34 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 long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to engine and transmission fluids, many acids, and chlorinated solvents. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life.

Typical settings include oil and gas, semiconductor equipment, and high-temperature process equipment.
