FVMQ, Fluorosilicone O-Rings & Seals

The common material-name for Fluorosilicone O-Rings is fluorovinylmethyl silicone rubber. Fluorosilicones combine the best properties of fluorocarbons and silicones. Fluorosilicones resist solvents, fuel, and oil (similar to fluorocarbons). This elastomer also has high and low temperature stability (as with silicones). Fluorosilicones are resilient, with low compression set characteristics. Fluorsilicones are widely used in aerospace fuel systems and auto fuel emission controls. High friction tendencies, limited strength, and poor abrasion resistance disqualify them from dynamic uses.
