Elastomers meet auto fuel system needs

DuPont Dow Elastomers has introduced the Viton AL family of fluoroelastomers – specially designed to help automotive fuel system designers meet tough new Euro 2000 emission regulations at no increase to their standard fluoroelastomer costs.

Viton AL provides low permeation, high temperature resistance, and extended low temperature flexibility, particularly for fuel system sealing applications such as fuel injector O-ring seals where operation at -40 degrees C is becoming mandatory.

According to DuPont, Viton AL is expected to become the chosen standard fluoroelastomer for automotive fuel system sealing, and for system upgrades in replacement of materials such as nitrile rubber, since it offers the best balance f all properties at economic cost.

New Viton AL grades provide the same advantages as A grades, with the additional advantage of improved low temperature flexibility.
