Vaseline can work as a substitute for dielectric grease, the big differences are that it can degrade rubber and plastics over time, and it's combustible – but I‘ve used it in the past on car bulbs, wiring and battery terminals and it hasn't been a problem yet.

Consequently, can you use petroleum jelly as dielectric grease?

Dielectric grease is not an electric conductor while anything soaked in petroleum jelly will burn if exposed to heat or an electric current. Also, Vaseline has a very low melting point compared to the dielectric grease which can withstand extreme temperatures.

Also, can you use Vaseline for bulb grease? Petroleum jelly is dielectric and acts as an insulator. If you get any of the petroleum jelly on the contact it can cause the bulb not to function. Some lubricants will dry over time and either corrode or create a “glue” making the bulb difficult to remove.

Consequently, what can I use instead of dielectric grease?

Substitute for dielectric grease. Would that be Vaseline (petroleum jelly)?

Is Vaseline electrically conductive?

Vaseline is petroleum jelly and is in fact electrically conductive. That's why you use it in preference to other forms of grease. It's purpose is to inhibit corrosion and fill any air gap that would promote ozone build up in the joint.

Related Question Answers

Where is dielectric grease used?

To use dielectric grease during an automotive tune-up on a gasoline or diesel engine, apply a bit of the grease to the end of the rubber boot on a spark plug wire and spread it around so it is just covering the inside of the lip.

Can you use too much dielectric grease?

Dielectric grease is an insulator. It should be used sparingly for corrosion resistance. Yes, if gooped on too heavily, it will cause issues.

What is dielectric grease made of?

Silicone grease, sometimes called dielectric grease, is a waterproof grease made by combining a silicone oil with a thickener. Most commonly, the silicone oil is polydimethylsiloxane (PDMS) and the thickener is amorphous fumed silica.

Is silicone grease the same as dielectric grease?

Dielectric grease does not conduct electricity and stays pliable (it does not cure), while silicone grease does not conduct electricity either but cures to a hard form.

Does dielectric grease improve connection?

Some claim dielectric grease is conductive or abrasive, containing silica that increases wear. (It doesn't contain silica). The most frequent Internet complaint is that dielectric grease insulates connections, making connections less conductive. Some call pure silicone grease an “insulating grease“.

Is Lithium Grease electrically conductive?

Lithium grease is generally non-conductive, but meant for lubricating mechanisms, not restoring corroded switch contacts. Lithium grease is used at high temperatures when silicone grease is unsatisfactory.

Is dielectric grease necessary?

Chances are, without the dielectric grease, you will destroy the wire if you have to take one off the plug. The boot will be infused to the plug. That's why you should use anti seize on bolts so they don't break off due to aluminum oxidation. they also help with any water.

What is the best dielectric grease?

Best Dielectric Grease: Top 3 Formula in the Market
  • Permatex 22058 Dielectric Tune-Up Grease, 3 oz. Tube.
  • CRC Di-Electric Grease, 10 oz Aerosol Can, Opaque White.
  • MISSION AUTOMOTIVE Dielectric Grease/Silicone Paste/Waterproof Marine Grease (8 Oz.) Made in USA- Excellent Silicone Grease.

Is white lithium grease the same as dielectric grease?

The word dielectric simply means non-conducting which is nearly synonymous with the word insulator, meaning it does not allow the flow of electrical current. White lithium grease is a multi-purpose grease used for gears on all locomotives, including those with motor worm gears.

What is the difference between white lithium grease and lithium grease?

I understand that most automotive greases use lithium as a thickener (i.e. the soap which keeps whatever oil the grease has as its base). From what I can gather, the only difference with ‘WHITE lithium grease‘ is that it has zinc-oxide added to it – but why?

Should you put dielectric grease on ignition coils?

It is a preferred grease for automotive ignition applications because ignition systems use rubber boots to keep the spark plugs and spark plug wires away from moisture Silicone dielectric grease is used on the bottom of the inside of the ignition coil boot where the spark plug meets the ignition coil.

Does Walmart sell dielectric grease?

CRC Industries, Inc. 05109 Dielectric Grease . 5Oz Tube – Walmart.com.

Can you lubricate a light bulb socket?

To combat this sticky situation and forestall distress, lube the threads of your light bulb with a bit of petroleum jelly; that's Vaseline to you and me. Just a dab on the tip of your finger will do.

What is electrical contact grease?

NO-OX-ID “A-SPECIAL Electrical Grade” is the electrical contact grease of choice for new electrical installations and maintenance. NO-OX-ID electrical contact lubricant (electrical contact grease) is an electrically conductive grease that keeps metals free from rust and corrosion.

Do you need to put grease on spark plugs?

It's very important not to over or under tighten spark plugs during installation. If your engine has the more modern ‘COP' system (coil-on-plug) then lube the spark plug boot with dielectric grease, this helps prevent misfires and makes removing easier in the future.

Is there a good substitute for dielectric grease?

Vaseline and dielectric grease are widely used in wire connectors of motorcycles and automobiles to keep the moisture out and prevent the connections from rusting and sticking. There are different opinions on how to use them and if one is better than other.

Can you use silicone spray on electrical connections?

DO NOT USE SILICONE SPRAY ON ELECTRICAL CONNECTIONS, SWITCHES, RELAYS, ETC. There have been numerous reports that silicone spray can cause contact problems in switches, noted in multiple posts regarding automotive problems.

Is it OK to use Vaseline on battery terminals?

Before winter starts, disconnect the terminals and clean them with a wire brush. Reconnect, then smear with petroleum jelly. The jelly will prevent corrosion and help keep the battery cranking all winter long.
