Product Information

Only pure dielectric silicone greases should be used in single high voltage connections, such as spark plug boots or other high voltage connectors (x-ray, neon sign, or HV power lines). In most cases, only a light coating or wipe is required. In the presence of moisture, dielectric grease will actually accelerate voltage breakdown across insulators. Metalized grease should never be used or allowed near HV connections.

Various types including petroleum-based, white lithium, and dielectric grease, each with unique benefits. Gold plated will quite often still need a connector grease as the gold plating is microscopically porous and can easily be compromised, especially during initial mating of the connector.Dielectric grease can be used on ignition coil connectors and other ignition components. It’s a good product to prevent voltage leakage from occurring.

These terminals are the bridge for electrical current flow to and from the battery, powering everything from the ignition system to the headlights and the car’s computer system. With so many functions being controlled by electrical signals in modern cars, the integrity of the electrical circuitry of a car has become supercritical. One of the most important elements is the ground connection. What I have found to work even better is to apply conductive grease on an electrical connection, wipe off excess grease, and seal the connection with a generous amount of dielectric grease. This keeps the conductive grease from flowing to unintended areas. Most people would not recognize dielectric grease from regular grease, much less explain how the two types of grease are different. Many drivers confuse the two or assume they are interchangeable. Both dielectric and regular grease have similar and different ingredients that make them unique but define the role each plays as a lubricant and protectant. When the ground connection is not good, the electronics, sensors, lights, and other electrical accessories in a car will not function properly. Also, the battery may not charge properly.

Features & Benefits

In this guide, I touch on the basics of dielectric grease. I evaluate the pros and cons of the lubricant, and I show you when and how to use it. I also determine the differences between two popular automotive grease types. What is Dielectric Grease? If you apply a conductive grease, will the next engineer/technician realise it is conductive? Will the correct precautions be taken when the connector is unmated and reconnected? Permatex makes a dielectric grease that lists both silicon dioxide and polydimethylsiloxane as ingredients. If you look at the color of this grease, it should appear milky or translucent gray. Dielectric Grease Pros 1. Creates Seal Because optimal additive design of these penetrating types offers them exceptional wear and corrosion resistance, petroleum and vegetable oils penetrate best and are the easiest to apply. Oil type lubricants have a fluid feature that helps to wash the rope and eliminate harsh exterior impurities. Permatex Dielectric Tune Up Grease and a specific heatsink compound used on high-power transistors are virtually identical. Even 1 percent Vaseline is preferable to bare metal-on-metal.

All of these dielectric greases, as well as almost all other brands, improve insulation while also preserving electrical connections. They achieve this by sealing connections to keep pollutants, moisture, and air out. They help keep moisture and pollutants out of insulation by sealing insulators. They’re just as good as “conductive” grease in keeping connections together, and they don’t degrade insulation. Historic Applications of Silicone Dielectric Grease This grease holds up under extreme temperatures. It will continue providing a seal, even when temperatures reach 500 degrees Fahrenheit. 2. Protects Plastics The best dielectric connector grease for resistance to water and salt water – the product in this list that has the best water resistance properties.This is a common choice for battery terminals. It’s effective in preventing corrosion and is widely available. However, it’s not always the best choice for high-temperature environments as it can melt and run. White Lithium Grease One of the most common uses of dielectric grease is on battery terminals to protect them from corroding. Auto mechanics also apply silicon grease on spark plugs to prevent the loss of spark as part of car tuning. Maybe take a look at our short article – Conductive grease not recommended for use on electrical connectors (opens in new tab). Dielectric grease offers a strong seal for metal surfaces. It can be used on the electrical system’s metal components to prevent corrosion and rust.
