 Viton® F - 70% Fluorine Best–Chemical Resistance The "F" family of Viton® was designed for todays oxygenated fuels, modern lubricants, and blended chemicals. As new chemicals and fuels are developed, new technology in Viton® has led to the development of the Viton® F family of sealing products. Chemical Resistance Viton® F offers superior fluid resistance and very low permeation in very aggressive environments. Viton® F offers excellent resistance to fluids that Viton® A and B types cannot adequately resist. Viton® F types are highly resistant to oxygenated fuels containing (MeOH, EtOH, MTBE), engine lubricants (SE-SF and SG-SH grades), aromatic hydrocarbon process fluids, chemicals and concentrated mineral acids.
