Dielectric Grease is a special kind of lubricant designed to create an effective barrier against moisture and other contaminants. It is commonly used on electrical systems such as spark plugs, ignition coils, and terminals in vehicles, sensor connections, outdoor equipment, marine connections and lighting systems. Dielectric Grease helps protect these critical components from corrosion and shorting out due to moisture exposure. It can also help improve the performance of high-energy ignition systems such as those found in modern cars and trucks. Using Dielectric Grease will ensure a better connection and better performance in harsh environmental conditions.
