Permatex® 22058 - Dielectric Tune-Up Grease

If moisture gets into electrical connections and causes corrosion, it can affect the operation of the entire electrical system. The task of a dielectric grease is to keep moisture out of electrical connections and prevent contaminants like salt and grit from damaging or corroding these connections. It is also used to provide a seal and protect rubber gaskets on electrical connectors. Its high heat resistance makes it safe for use in applications with a high temperature environment.

This Dielectric Tune-Up Grease by Permatex is a silicone compound with superior dielectric and lubricating properties that help to facilitate and improve tune-ups. It prevents voltage leakage around any electrical connector thereby ensuring a strong spark in modern high energy ignition systems. This product is an excellent lubricant on rubber, plastic and ceramic surfaces with good high temperature properties. Sometimes it's really hard to remove a spark plug wire boot from a spark plug to the point where the wire ends up being pulled. This dielectric grease ensures that the boot will not fuse to the plug, making removal easier.
