Viton 75-159-Black-Pk2

Ordered as SB-V70159-2, this is an AS568-159 black Viton® (FKM) 70 Shore A O-Ring built to an inside diameter of 4.987 in (126.67 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.193 in (131.9 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Additional detail on this item: 0.103CSX4.987"IDX5.193"OD.

Expect good resistance to many acids, chlorinated solvents, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. The material carries a published service range of -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.

Common environments for this compound include oil and gas, high-temperature process equipment, and semiconductor equipment.
