Fluorosilicone O-Rings

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

Fluorosilicone O-Rings

Fluorosilicone O-Rings Description:

Fluorosilicone 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 O-Rings Properties:

Poor Wear Resistance, Moderate Comp. Set Resistance, Moderate Short-Term Resilience, Poor Permeation Resistance

Fluorosilicone O-Rings Temperature Range:

-80ºF to 450ºF

Fluorosilicone O-Rings Recommended For:

Jet Fuel, Dry Heat, Wide Temperature Range, Some Petroleum Oils, Chlorinated Solvents

Fluorosilicone O-Rings NOT recommended For:

Ketones (MEK), Phosphate Esters, Some Acids, Auto / Aircraft Brake Fluids, Amines (Ammonia)
