Viton® (FKM) is valued for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. The material holds up against chlorinated solvents, aggressive chemicals, and petroleum oils and fuels. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or low-molecular-weight organic acids will shorten service life.
Typical settings include semiconductor equipment, automotive fuel systems, and chemical processing.
SB-V70439-2 ships by the bag. Nominal inside diameter is listed as 6 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
