Fluorosilicone O-Rings

O-Rings made of Fluorosilicone are generally used in chemical applications.

Fluorosilicone O-Rings

Fluorosilicone O-Rings Description:

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

Fluorosilicone is the material produced by compounding fluoroelastomer (FKM) and silicone. With great compression set and performance in high and low temperatures, fluorosilicone o-rings are becoming more widely accepted for general purpose use. Fluorosilicone O-rings are typically blue in color and have an unlimited shelf life. Get in touch with us today to order high-quality, customizable Fluorosilicone O-rings for your business.
