Viton® O-Ring and seal performance cost benefit makes it the second most popular sealing material. Fluoroelastomer (Viton®, FKM) offers a wide range of resistance to chemicals, oil and heat, with situational service life above 200°C. The outstanding heat stability and excellent resistances are due to the high ratio of fluorine to hydrogen, the strength of the carbon-fluorine bond, and the absence of unsaturation. FKM compounds are widely used in chemical, automotive, aerospace and industrial applications. Fluoroelastomers are referred to generically as FKM polymers per the nomenclature noted in ASTM D1418. In the SAE J200 ASTM D2000 classification system for rubber materials Fluoroelastomers are documented as a "HK".
