Description: Fluorosilicone Rubber Blue O-rings

Fluorosilicone rubber is an inorganic "hybrid" elastomer which combines the wide temperature range spectrum of silicone with some of the chemical resistance of fluorocarbon rubber. Primary use is in fuel delivery systems. Fluorosilicone rubber offers the best low temperature properties of any oil resistant rubber. Like all compounds based on silicone rubber, fluorosilicones have relatively low tear strength, abrasion resistance, and tensile strength, and therefore, are generally not suited to dynamic applications.
