Although sold for automobile bulb sockets (for which it works great), this product is actually silicon grease. "Dielectric" means that the silicon grease is an electronic insulator. See also Fantasea Silicon Grease Lubricant, "for all types of O-Rings"

Although ordinary automotive grease is very damaging to rubber products, silicon grease is great for ANY rubber products, and for use on ANY electronic connection (other than high-voltage switches). Not only does silicon grease prevent corrosion at electrical contacts, it also improves existing contacts.

After about 5 years of flawless operation, recently I got a "blue screen of death" on my computer, mentioning a parity-check error. I removed the memory boards, cleaned the contacts with isopropyl alcohol, applied a thin layer of silicon grease to the contacts on the memory boards, and reinstalled the memory. The computer works perfectly. It would be a good idea to coat the contacts of any boards or memory with silicon grease before installing.

Does your car refuse too start when it's been raining for days? You could replace the entire ignition harness (for perhaps $100 plus labor)---or just coat the wires with silicon grease, being particular generous at the spark plug and distributor connections. No need to wipe off excess. Also pull off the spark plug wires (one at a time so you don't confuse them) and put a dollup of grease on the contacts.

Replacing your car battery? This stuff is far better than the petroleum jelly your father used to protect the contacts from corrosion.

Is your bathroom faucet leaking? Disassemble it, clean it, and rub silicon grease into all of the rubber seals. Let it set, wipe off excess, reassemble.

Is the A/C plug for your juicer hard to push into the socket? Add a generous coating of silicon grease and stick it in and out of the socket several times to lubricate the socket. Petroleum-based grease or oil may conduct electricity and burn---making the connection worse. Silicon grease will not conduct electricity nor burn.

Is the door lock of your car stiff? Same solution, slather silicon grease on the key, and lock/unlock the door several times.

Does the right or left channel of your headphones drop out or sputter? Silicon grease will improve the connection.

Do you have to shake your TV remote to make it work? Silicon grease will improve the batteries connections.

Have you noticed? 40 years ago leaking battereies destroyed uncountable flashlights and transistor radios. Everyone knew that you had to remove batteries when not in use. But then battereies improved in the 1980s and 1990s and almost never leaked. But once again, batteries are leaking and damaging equipment. Silicon grease will at least protect your contacts from minor leaks, and will improve already damaged contacts.

Does wind noise at high speed because of a poor door seal drive you crazy? Coat the seal with silicon grease. Rub it in, let it set, wipe off excess

Do you have a classic car with stiff dried-out rubber seals? This stuff is first aid. If they aren't too dead, silicon grease will bring them back to life, and protect them from further deterioration.

Sliding windows in your van hard to open/close? Coat the channels with silicon grease.

Within reason, you cannot use too much. Unlike ordinary oil and grease silicon grease does not attract dirt.

Caution: Silicon grease is NOT a replacement for petroleum-based grease as a lubricant for continuously moving mechanical parts. While silicon grease can "recondition" rubber belts and rollers (in computer printers, etc) it can also make them too slippery to do their job (use CaiKleenTM RBR Liquid, oiler dispenser concentrate 25 mL). Silicon grease can interfere with repainting cars---so it is best to avoid getting silicon grease on painted surfaces, particularly if you anticipate repainting the surfaces in the near future. In high-voltage switches, arcing can create silicon carbide which will deteriorate the contacts.

Using a little Permatex Dielectric grease on the spark plug connectors will help remove them later as well as sealing out moisture.

This tube is bigger than you think. I used this item as a filler to get free shipping!. I use it mainly for placing on the car bulbs when i replace them, or for spark plug wires. This stuff works great, and is recommended to have just in case you need to waterproof a connector!

I use this stuff all the time. My latest job that I used this for was installing a security system at a car wash. I coated the insides and outsides of all the connectors with this grease. It should help prevent moisture from destroying the connectors.I use this stuff liberally on spark plug boots and and in engine compartment connectors. I usually use too much to the point where it squirts out and around the connectors. That way I know that there's plenty in there so moisture can't get in. I coated the connectors on my father's Explorer's alternator with this stuff. I use it to help prevent corrosion on battery terminals. I use it all the time. It's in my tool box on the top tray ready to be used at a moment's notice.

I was having a problem with deposits building up on my car battery terminals that was interfereing with a good connection and eventually killing the battery. I coated the terminals with permatex and it seems to be staying deposit free. It has been about 2 1/2 months.

This costs an arm and a leg at parts stores for much less product. I got tired of paying 3 dollars for 10cc's of dielectric grease and this is a great solution. Bottle is equal to normal Permatex silicone bottles. I don't know why parts stores don't sell these.Dielectric is one of those things you don't think about until you need it then you end up paying to much. I'm glad to have this in my garage.

I've been using Permatex dielectric compound for 20+ years on all types of electrical connections on my vehicle repairs (professionally and privately)It prevents corrosion and wear on contacts and splices, waterproofs connectors etc., I almost never make a connection without using it, Highly recommended

Ever had a COP spark plug boot tear apart on the #4 cylinder of an Expedition? They are a real pain to get the remainder of the boot off the spark plug just so you can get the socket on... It wouldn't have happened had this been applied prior to installation... Also great for electrical plugs & bulbs to prevent corrosion, o-ring lubrication, heat sink compound for ignition modules, and, I'm sure you could find dozens of other uses for a non-reactive, non-conductive silicone based grease...

I use this grease when I am changing my spark plugs. Does its job well.

dielectic grease is a must installed on pull end and inside plug boots to prevent damage to plug boots when changing plugs.
