APG stocks the VITON75911, an AS568-911 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 0.863 in (21.92 mm), a cross section of 0.116 in (2.95 mm), and an outside diameter of 1.095 in (27.81 mm). An 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 excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. The compound resists aromatic hydrocarbons, aggressive chemicals, and many acids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or amines will shorten service life.
It sees regular use in high-temperature process equipment, semiconductor equipment, and aerospace.
Order part number VITON75911, sold individually. Unit weight is approximately 0.9867 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
