Universal Dielectric Tune-Up Grease by Permatex®. This dielectric grease has been specially developed to protect electrical connections and wiring from salt, dirt and corrosion. Because dielectric grease is non-conductive, it prevents voltage leakage around any electrical connection. This product also extends the life of bulb sockets. Required for modern high energy ignition systems.

Notes: Suggested Applications: All electrical connections, spark plug boots, trailer hitches.


  • Silicone dielectric compound
  • Improves connections
  • Prevents corrosion
  • Prevents spark plugs from fusing to boots
  • Makes installation of the boots easier
  • Resistant to high temperatures
  • Excellent rubber lubricant

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.

Does It's Job
Helped to moisturize my boots for my ignition coils. My only complaint is that I had to pay 11.95 to ship this tiny, tiny, package. I know it does not cost that much to ship it. Probably won't order from here again for this reason.

Permatex Tune-up Grease
I use this grease specifically for lubing light bulb sockets so that the bulbs don't stick and break upon removal. It works great.

Very Good Product
I have never use dielectric grease before but my son uses it when he changes headlights and other lights. Don't use much so this will last many decades. Auto manufactures recommend this product when installing new headlight bulbs. Makes it easier to remove burned out bulbs.
