Is dielectric grease necessary and conductive? [Explained]

Electrical connectors like battery, spark plugs and all other things that conduct electricity needs an insulator. In addition, the insulator is essential for the maintenance of those connecting points.

Dielectric grease becomes a thing of great necessity as a non-conductor or the insulator. However, depending on the individual’s need, protection from corrosion, maintaining an overall healthy connection, and so on are preferable that required a dielectric grease.

is dielectric grease necessary for spark plugs? purpose of dielectric grease

Dielectric grease is designed and made for spark plugs. It has unique features that work to better the different parts of the vehicle and engine. For example, spark plugs help transfer electric current from the ignition point to the combustion chamber in an engine system.

Dielectric grease should be used on spark plugs for some of the following reasons:

• A proper seal is ensured for the spark plugs in case of dielectric grease.
• A spark plug is a kind of electric connector that requires extra safety to better its use. In addition, dielectric grease provides additional insulation to these connectors.
• The durability and longevity of the plug are added with the help of dielectric grease.
• The plug is protected from the attack of dust, dirt, and even corrosion. Furthermore, all the foreign objects are restricted from entering due to the seal of the grease.
• Although it doesn’t improve the connection due to the non-conductivity of the current, the grease helps to maintain the connection.

Where should you not use dielectric grease?

Dielectric grease is a component made for the usage of electric points and connectors. Before their use, one should know about their quality and prominent feature. Going to their capability of working, their main job is to provide insulation and add a form of resistance to the flow of current.

After knowing the feature of dielectric grease, any technician can easily understand where and how to use them in the right place. An added guide on the usage of dielectric grease and where it shouldn’t be used are as follows:

• Dielectric grease should never be used on the path of the flow of current.
• They shouldn’t be applied to the electric connector points to create an obstacle in the electric flow.
• The sockets and the pins should be kept away from the contact of dielectric greases present in an electric connection.
• It is suggested to keep them away from using in between the battery terminals.

How to apply dielectric grease to a spark plug boot?

To attain a desired output from the dielectric grease, a seamless application and perfect methods should be ensured. That is the same for a spark plug boot that may need a dielectric grease solution.

The proper working of the spark plugs requires adequate pins’ functioning, which can be maintained through some unique properties. For example, dielectric grease is the best component for your spark plug to ensure its longevity, safety, and proper working.

 The application of dielectric grease for the best out of the spark plug boots are as mentioned:

• First of all, the cleaning of both the plug and the boot should be ensured.
• Squirting a certain amount of grease on the cardboard, use a swab of cotton for the small number of applications on the boot.
• The boot’s inner wall is made contact with the dielectric grease, and the boot is then ready to go after keeping it back to its place.

What is the difference between silicone grease and dielectric grease?

Dielectric grease and silicone grease are almost the same product made out of the standard component called silicone. Their last job is to serve the electric connectors to create seals and insulation to protect the connectors from foreign objects.

Despite being identical, there are some slight differences between silicone grease and dielectric grease mentioned in the below table:

Should you use copper grease/slip/anti-seize on spark plug threads?

No, it would help if you never considered any anti-seize or copper grease for the spark threads. These copper grease or slip or anti-seize are lubricants that can impact negatively if used in the lines of spark plugs. The negative effect is usually expected due to the penetration of the oils inside the cylinder.

Some of the common reasons behind not using any copper grease on the spark plug threads are:

• The application of the copper grease can be hazardous as the plug is removed. The lubricant can penetrate the cylinder, which is very much harmful.
• The spark plugs thread becomes more reasonable with breakage for the following lubricants.
• The shells of the metal can also lead to specific stretches for the application of copper grease.

Does dielectric grease improve connection?

Dielectric grease doesn’t improve connection. It aids in maintaining the relationship but can’t improve it by any means. Some of the reasons for which they are incapable of enhancing relations are:

• Dielectric grease doesn’t conduct electricity, so it cannot help improve the electricity connections.
• The central tendency of an electric connection is to conduct and flow current. A dielectric grease holds the opposite nature for this.
• The dielectric grease can even create obstacles in the connection by stopping the flow of current is used wrong.
• Protection against dust, dirt, and other foreign objects and through proper insulation, a good connection is maintained.

Is it OK to put dielectric grease on battery terminals?

Dielectric grease can be used on battery terminals but with the same safety precautions. You can only use it according to the prescribed instructions as it can stop the conduct of electricity. Dielectric grease can be used on battery if and only if some specific things are kept in mind:

• The dielectric grease should not be used in between battery terminals as it can obstruct the conductivity of electricity.
• The grease can be used in other ways to prevent the battery from corrosion and maintain the battery performance.
• But, the improper use of dielectric grease can negatively impact the connection and shorten the life.
• The terminals post should be cleaned to apply the grease. Then the cables of the terminals should be re-attached.
• In this way, no interference in the electric connection is ensured and OK to be used for the battery.

Conclusion

Curiously, dielectric grease is an excellent form of support and benefits electric connections like spark plugs, battery terminals, etc. They help in aiding the links through insulation, seal, and protection against foreign objects. Besides protecting from dirt and dust, they are known for the prevention of harmful corrosion.

Dielectric grease is unnecessary until you get the urge to ensure the connector points’ longevity, safety, and healthy connections.
