Excellent Heat Stability (200°C) • Superior Aggressive Fuel and Chemical Resistance • High-Performance Elastomer

FKM/Viton Rubber Products

All of our Fluoroelastomer (FKM) products are manufactured with 100% virgin FKM Fluoroelastomer polymer sourced from the world’s leading manufacturers. Fluoroelastomers were originally introduced over 50 years ago to meet the needs of the aerospace industry for a high-performance elastomer. Since then, the use of fluoroelastomers has spread quickly to many other industries, including the automotive, oil, fluid power, appliance and chemical industries and has developed a reputation for its outstanding performance in very hot and extremely corrosive environments. Fluoroelastomers are particularly valued for their excellent heat stability (200°C) and resistance to aggressive fuels and chemicals.
