Part number VB75M3X255 is a brown Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 255 mm (10.039 in), a cross section of 3 mm (0.118 in), and an outside diameter of 261 mm (10.28 in). 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 outstanding high-temperature capability and very low compression set at elevated temperature. Expect good resistance to many acids, engine and transmission fluids, and chlorinated solvents. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or amines will shorten service life.
You will find this material specified across automotive fuel systems, high-temperature process equipment, and aerospace.
Stocked as VB75M3X255 and sold individually. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
