The material holds up against chlorinated solvents, petroleum oils and fuels, and many acids. That behavior comes from the compound itself: Viton® (FKM) is valued for very low compression set at elevated temperature and outstanding high-temperature capability. Verify compatibility before use with amines or low-molecular-weight organic acids.

It sees regular use in high-temperature process equipment, automotive fuel systems, and oil and gas.

0283VB210 ships by the foot. 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.
