VITON75277 is an AS568-277 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 11.484 in (291.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.762 in (298.75 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Viton® (FKM) is widely chosen for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. It resists many acids, aggressive chemicals, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or low-molecular-weight organic acids call for a different compound.
Typical settings include high-temperature process equipment, semiconductor equipment, and aerospace.
Stocked as VITON75277 and sold individually. Unit weight is approximately 16.63 g and nominal inside diameter is listed as 11 1/2 inch.
