Why is Viton (FPM) rated this way to Acetonitrile?
Viton (FPM) has limited resistance to Acetonitrile. Short-term exposure may be acceptable, but prolonged contact is not recommended.
⚠️ When NOT to use Viton (FPM)
Avoid using Viton Fluoroelastomer with ketones, esters, amines, and hot water/steam. Excellent for fuel and oil applications.
