Since dielectric grease is a silicone grease, it should not be used on silicone-based rubbers or plastics, as it will break them down over time. The grease does not conduct electricity, so it shouldn’t be applied directly to the mating surfaces (pins and sockets) of an electrical 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“.
Subsequently, question is, can I use Vaseline instead of dielectric grease? 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.
Also Know, is there a good substitute for dielectric grease?
Just don’t use anything with silicone or petroleum distillatesthey will eventually damage the rubber. Silicone does not damage the rubber, but petroleum distillates do damage the rubber. Dielectric grease is silicone-based. McMaster sells a 5.3-oz tube for $15, so if you can get it for $5, go for it.
Does dielectric grease increase conductivity?
Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion. The grease does not conduct electricity, so it shouldn’t be applied directly to the mating surfaces (pins and sockets) of an electrical connection.
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.
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 the difference between silicone grease and 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.
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.
Does Walmart sell dielectric grease?
CRC Industries, Inc. 05109 Dielectric Grease . 5Oz Tube – Walmart.com.
Should I use dielectric grease on a distributor cap?
Yes put a small dab of dielectric grease on the contact pins of the cap and the the rotor center/end points. This is SOP on all cap & rotor, as well as sparkplug boot installation.
Is Vaseline good for electrical connections?
Petroleum jelly and similar products, if pure, are not conductors. In electrical engineering, petroleum jelly is often smeared on terminals as a measure to prevent corrosion, especially battery terminals.
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 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.
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.
Should you use dielectric grease on spark plugs?
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 wd40 help electrical connections?
WD-40 does not conduct electricity: When you put the connectors together, the metal on metal of the connector will allow the electricity just fine, but with the WD-40 in there, you won’t have an issue with something cross connecting or electricity bleeding off to somewhere you don’t want it to.
