Viton 75-155-Black-Pk2

Ordered as SB-V70155-2, this is an AS568-155 black Viton® (FKM) 70 Shore A O-Ring built to 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). The o-ring remains the most cost-effective sealing element available for pressurized assemblies. Source specification: 0.103CSX3.987"IDX4.193"OD.

Viton® (FKM) is specified here for excellent resistance to compression set and permeation, industry benchmark where nitrile reaches its thermal limit. Expect good resistance to petroleum oils and fuels, chlorinated solvents, and aggressive chemicals. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or ketones and esters will shorten service life.

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