APG stocks the V3X185, a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 185 mm (7.283 in), a cross section of 3 mm (0.118 in), and an outside diameter of 191 mm (7.52 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Viton® (FKM) is widely chosen for outstanding high-temperature capability, excellent resistance to compression set and permeation. Expect good resistance to aggressive chemicals, engine and transmission fluids, and petroleum oils and fuels. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.
You will find this material specified across semiconductor equipment, aerospace, and chemical processing.
This item is sold individually under part number V3X185. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
