Material properties
Fluorocarbon rubber (FKM), known by the trade name Viton, is a premium elastomer for high-temperature and chemically demanding applications. It offers very good resistance to mineral oils, aromatic hydrocarbons, fuels including biodiesel, mineral acids, hot oils, ozone and oxygen. Operating temperature range is -20 °C to +200 °C, short-term up to +230 °C. It is an OEM standard for automotive engine seals. Not suitable for amines, ketones, esters, glycol-based brake fluids, hot water and steam.
