Fluorosilicone combines the fuel and oil resistance of a fluoroelastomer with the very wide temperature capability of silicone.
Fluorosilicone gives you the fuel and oil resistance of a fluoroelastomer with the very wide temperature range of silicone. It is the material of choice when a seal must stay elastic at low temperature and still resist fuel and oil at high temperature.

Key Features
