I believe in dielectric grease only to keep moisture from corroding contacts... been using it for decades and will continue!
I feel like the number of people who think dielectric grease is a conductor are balanced out by the people who think it will actually prevent electricity from flowing through a good connection.
Im probably one of them, lol, if someone puts it on a battery post and the part that bolts to the post it seems like it would lose some continuity even after it pushes the grease out, because noway will it push it all out, would still be a thin layer, I have read so many comments about this grease and it seems like multiple people have different explanations of how it works, I know it's not conductive,
What is the difference in dielectric grease and dielectric paste?
I just use wd40
Dielectric grease is not an electrical conductor, why do you want to contaminate the interface?
I have been using die electric grease and even Vaseline for years over my battery terminals for years with no issues. I believe that you would not degrade your connection if you connect the battery terminals first then apply the dielectric grease to inhibit corrosion.
@@rfcasey Factory shop manuals instruct this? The way I see it, repeated heating cycles are likely to polymerize the grease trapped in the interface.
If it was conductive , all the pins on a multi pin connector would be shorted together or even to ground in other cases , I tried to explain this to a guy at work. He just wanted to fight over it. Thanks for your demonstration, good work .
Exactly! You use dielectric grease because it does not conduct electricity, where other greases may conduct electricity and short out connectors. Dielectric grease does prevent water from entering the connector to prevent rust and corrosion and since water is electrically conductive, it could short the connection.
@@chrisgraham2904 exactly 👌
It seems like EVERYBODY want to fight about this -
You'd think we were talking politics!!!
It is really great that it is nonconductive, else it would be totally pointless !!!! imagine all the short circuits you would have if it was. :-)
Thank you so much, so many are confused about dielectric grease. You explained it perfectly!
It helps keep water out that's why people use it
Looks and the English language can be deceiving is a underrated statement🤭
You nailed it! This is the best video on this subject I have seen yet!
Dielectric is literally an insulator similar to wire insulation. It works well on cleaned-up electrical contacts because: 1) keeps connections clean and weather/contaminate resistant, 2) lubricating electrical contacts providing a tighter fit by increasing the surface area of "Certain Applications" such as a threaded battery terminal connection. Silicone enables the bolt 🔩 to drive deeper inside the tap resulting in more surface area... THUS, increasing the conductivity in that instance!
As an electrical reliability freak, I find this treatment of a very valuable material to be most coooool!
If it were conductive, it would short out the connector
Great video, great content! I wish you more success!
A short video packed with useful information. Thank you 🙏 👏👏👏👏👏👏👏👏👏
3 years later yet the editing is still great bro . Thanks
Thats makes so much sense.. other videos made me think it was a mistake putting this on. Thank you
It insulates from shorts to ground and prevents corrosion on the contacts; it can also sure up a connection by eliminating looseness thus ensuring the contacts are mated. Good video.
A dielectric is literally an insulator
PERFECTLY DESCRIBED!
Thank you for the perfect video about what is actually going on!
Beautifully explained.
Great video!
Excellent video
you need to measure actual voltage drop ...... i use dialectic grease on all insulated connectors as a deterrent from corrosion..... BUT in the PROPER areas AND in a PROPER amount
Great video, demonstration,and explanation! As a tech for 41+ years, I rarely use dielectric grease. In my opinion it simply can be used to prevent water intrusion and corrosion.
Great job thanks
Awesome video
Awesome!!
i had a friend who thought electrical tape was conductive LOL
Yeah folks believe a lot of misinformation out there. Much obliged for showing the truth of the matter. A properly made connector will push the grease OUT of the way. I've never used a lot of grease, but I never used a little bit. Just slap it on and go.
This guy is spot on! I had to learn the hard way after losing cranking power from the di electric grease smeared on the battery post. Thanks again!
@@hose8239 Yeah you can smear it on AFTER the terminals are connected. I did that in my 86 Ranger I used to have. I have a 97 Blazer now and it has a side-post battery with rubber covers so I don't bother with that anymore.
Thanks for this. I ordered some conductive carbon grease to improve grounding with the frame of my truck.
Although silicone grease can be called a dielectric, it is not "dielectric grease". Dielectric grease may be based on a silicone formula, but it is not the same as common silicone grease.
The main difference between the two is that silicon grease will eventually cure and go hard. whereas dielectric grease won't.
Good to know. Can I use dielectric grease everywhere I use silicone Grease?
@@littlereptilian7580 Yep.
SiliconE grease! Silicon is a hard silvery transition element.
If the dielectric grease was a conductor it would short out systems where the grease is making a connection between two terminals,like it would if you placed the connectors under water.
Great video
Totally dopey! Whoever said the grease itself was conductive?? The whole purpose of electrical grease is to keep the elements out and prolong the conductivity.
I used to use diectric grease on snow plow and semi light connectors. Problem was moisture would get into connectors, the grease would help retain the moisture and there would be shorts. Watched a video of a guy restoring a trawler in Australia, he used a spray on connectors that dried, did not restrict connectivity and prevented corrosion. Can't remember the name off hand but it works well. I figured it was designed for salt water applications so it would work well in snowy environments where salt is used on roadways and I have found it is much better than dielectric grease.
ALSO, there is carbon grease (looks black, very messy), manufacturer description states for improving electrical connections and dissipating electrostatic build up.
i put a dab on a piece of paper and then put probes from a multimeter on it, 1/10" apart, the resistance measured was 3000 ohms! so, it will conduct electricity, but very poorly.
there is specialized grease with silver particles in it, comes in a small syringe and costs over $50 and will conduct electricity very easily.
That Tterrag Nhah bloke is a pretty good actor!😉
not only nonconductive it is a good insulator. Main use is for insulating (and lubricating), spark plug boots, prevents tracking very effectively, especially good for insulating bothe ends of coil on plug boots (coil overs). We are talking many thousands of volts, so has to be good insulator.
It's used to stop spark gapping and to prevent corrosion in the marine environment. Never heard anyone ever say it was to improve conductivity. Put the plug boot on, then smear DG around the lip to prevent moisture intrusion. Put inside butt connectors to keep moisture out.
cool. im still using it, but no worries of cross arching . just protecting it from oxidation etc water etc
Adding too much grease may reduce contact surface between two metal…less conductive surface will increase heat in the remaining contact.. theoretically….
Good video
I never had a problem with greasing first before connecting.
And if i wanted to help conductivity like on starter motor and alternator terminals i use a little copper grease.
Thanks god bless
If you are concerned about conductivity you can get Dielectric grease that is impregnated with cooper powder and is conductive.
Now I have a question, and excuse my ignorance, I want to use a normal regular grease instead of dielectric grease on my ignition coil, would there be any difference? Or would it change conductivity, connectivity, corrosion aspects?
As long as the "regular" grease is not conductive, it shouldn't cause any issues.
It will work in theory but 'regular' grease is petroleum based and shouldn't be used on some plastics and elastomers. Dielectric grease is silicone based so it won't hurt or swell the seals or the body of the connection.
I heard first about dielectric in HS, when learned how capacitor is build and function. Between two conductor plates is placed a dielectric material (insulator).
Helps prevent voltage leakage.
Helps insulate the electrical connection in frigid conditions.
Protects against water damage.
Protects against corrosion.
Protects against dirt and grime.
Protects against heat damage.
Protects against material bonding.
Protects against electrical overheating.
This video is missing the real point. The grease eliminates the formation of oxidation and corrosion by the simple act of filling all voids (if adequate amount is applied) within the connector. The electrical connection is still made merely by the actual contact of the two metal contacts that actually sufficiently touch together adequately. As the video correctly states, the scraping action made at the metal connectors actually clear away only the grease between the 2 contact points.
Understanding the English language or not understanding it is the fault of schools and students that don't want to comprehend it. As for the grease indirectly it improves the connection by preventing oxidation so it maintains the conductivity.
From the uk some people say dont get it on the connecters only on the plastic around coil pack is this true. And how about spark plugs is it ok
Using DeoxIT on the contact pins improves conductivity AND protects against corrosion of the bare metal. Better conductivity reduces/eliminates pitting caused by hot spots along the surface of the metal. Dielectric grease does none of this. I use DeoxIT on everything where metal meets metal whether it's automotive, networking connections, HDMI, antennas, computer boards, light bulbs, switches... the list goes on and on.
Might not increase it, but it prevents corrosion and corrosion creates resistance. So in a way it can
Maybe use something else that does increase conductivity and stop corrosion!!! Lol
@@royblackburn1163 Ok like what?
@@debrajohnson4689 Aronix Aluminium contact paste, there are lots of products on the market , a good electrical connection is priority far better a good clean joint then put dielectric on the outside to prevent corrosion, as for having dielectric in air gaps and grooves does it not make more sense to have a conductive paste there instead? Using a dielectric in a joint is just plain silly think about it learn to think for yourself.
@@royblackburn1163 hard to find and expensive die grease and even vaseline is cheap and easy to find
@@royblackburn1163 In regular low voltage multiple-pin circuit connectors, such as automotive applications, flooding with a proper insulating grease of low-viscosity dielectric grease is perfectly acceptable unless a manufacturer recommends against it. The grease should have good stability and not contain metals in any form, and be specifically designed for use as a dielectric grease. This generally is a silicone dielectric grease, although some Teflon based greases are acceptable.
As shown, the grease is actually an insulator. Its main purpose is to ease the subsequent removal of parts like connectors and rubber spark plug boots that can heat-bake together and stop electricity "Leaking" out from underneath. Keep it away from the actual connection. It's also OK to use to help corrosion resistance on battery terminals and other exposed connections.
How wrong you are bud its to prevent oxidizing.. main purpose preventing baking? Is that why spark plugs have it lol
@@northwestrockgem9745 Hey pal, heating the boots will cause them to stick (oxidize or, if you will, bake on)to the insulator. If you think its not and insulator, coat the plug electrode with it and try to start the engine.
bah its designed to provide a seal from moisture and air where the surfaces contact. So it has to be on the surfaces where the contact happens.
If it lowers conductivity like in this video why would you use it on battery terminals?
@@barrysuss4421 First, clean the battery terminal and cable clamp. this ensures a good contact. Second, coat the Exterior of the terminal/cable connector with thin coat of dielectric grease. This helps stop battery terminal corrosion due to the ever-so-slight current leakage from the battery. Current will flow from the Positive terminal to the nearest ground across the battery. surface. The current loss is too small to even measure and the current leakage won't flatten the battery but it will cause corrosion. Hope this helps. PS you can use KY jelly or Vaseline also as well as commercial battery terminal spray.
Question, what kind of grease and where can I find one that will conduct electricity? I need one like that.
It's a non conductive shield for electric components, very well done.
Tank's
good . that will; cause a short dont want all lines connecting to each other . it protects. thanx i was worried i was like connecting each wire together causing a bloew out with die electric.
In that case, it's no different from regular grease? What justify the higher cost of the dielectric grease?
It’s just supposed to exclude moisture, petroleum jelly can do the same…for me, anyways…
Provided the contacts make solid tight contact, as to "scrape away" tge grease at that point. So it will protect a connection but not improve the connection..
...and aluminum antiseize is conductive. My dad put it on his spark plugs, electrodes and all, then couldn't figure out why his car wouldn't start.
Grease creates a barrier between two connections in my experiences as a lawnmower mechanic I hate it. I might would use wd-40 for corrosion that’s it
This is not just a confusion but full stupidity. If dielectric grease was conductive then short spark would ignite and burn down every single car.
is this what i need to put on a speedometer cable before reinstalling in speedometer in car?
Dielectric grease would work, bearing grease would be another option.
Never seize works the way most people think die electric does
Lol check out the disappearing act that black tablet does on the edge of the car lol 0:24
Is it useful on the rubber seals if your vehicle
Yes, it can be used to lubricate o rings and seals. Before using, check the label to see if it has any warnings about what fluids your dielectric grease should not come in contact with.
I prefer to use whatever fluid the o ring is going to be in contact with (oil for oil, coolant for coolant, etc.)
Great vid!👍🏼 I always had the burning ques of shood I put diel grease around my car batt post cables(after tightening them down),or smear it on the(b4 attaching post cables) to the battery posts and as wel as to outside of post cables after tightening them onto posts. I Nu I was rite!🤪
Car is completely dead using the grease.. Here in my place may 29 2021...the connections were bolted tight ...... car runs fine after using brake cleaner this video is not didn't work out for me
But it’s good on toast with cinnamon
👍🏻
if it was conductive it would short circuit shit by bridging electronics in any plug that has multiple wires
❤️
But it said inflammable, i didn't expect it to catch fire.
English is stupid mishmash of European languages
It should have been high ohmic or similar
I’ve never heard anybody say that dielectric grease improves conductivity my entire life I’ve heard people talk about using the ledge agrees on electrical connections to make them waterproof so that the water can’t get in the electrical fittings is that true does it help waterproof electrical fittings?
Dielectric grease can waterproof a connector. Periodically check the connector for any corrosion or adding more grease.
👍👍👍
Thank god it’s not conductive else it would short circuit the pins together in the conductor.
no... but it does SLOW DOWN water ingress....
i live in montana.... so it gets WHEELED HARD in snow
.
trans output shaft speed sensor codes..... because rusty 97 shitbox jeep things
un plug, spray out with contact cleaner/WD-40..let dry.... big glob of di-grease.... plug it back in
get about 100 miles and do it again lol
got pretty quick at it in -50F
If it konduked elektrikaoty it would ark out….. the kotakts would all make kontak with ea4 (each) other.
Interstate makes 9v wtf?
To each their own.....but the way you apply that grease hurts my feelings. I use a Q-tip.
So... Vaseline will work fine?
Yes, possibly, until you use it in a rubber connector, when it will dissolve the rubber. There's a reason di-electric grease and petroleum jelly both exist. I love watching videos where dickheads use vaseline on rubber gaskets and seals......instead of rubber grease.
@@einfelder8262 Thanks!
ask yourself ,do they sell vaseline in the auto parts store? vaseline is a petroleum base product , that means it can be and it is flamable ! and you want this on your spark plugs boots close to extreme heat?... so NO !
@@frankc6430 Oil is a petroleum product, they sell that at the auto parts store, so they probably sell vaseline too. Just sayin', your logic is illogical.
@@einfelder8262 why are you guessing just to voice your ignorance ? we are talking about Vaseline and Vaseline should not be used as a lubricant inside the spark plug boot because it is flammable... this is not about illogical sales of a product ,you should call them and ask at least not just guess stupidity!
I have a tub of silicone grease. doesnt say anything abt dielelectric. Is it the same thing?
Brand is Anabond silicone grease.
close enough, it is non conductive.
you can use white lithium too.
Diaelectric grease is insulative.
who bent your brush
Can anyone test this out and give feedback? study androidcircuitsolver on google
in my opinion anyone who uses any paste /grease/ spray /chemicals in general without knowing what exactly it is meant for is just hopping for miracles that some times seems to work but in the long run it can backfire and the ignorance can be more harmful and costly than the quick guess fix or hope , especially where water /heat/electric and fuel all combine in the same place .
Just a very thin smear is all you need.
Why are people afraid or too lazy to use reference books like a dictionary?
Get ride of the reusable trash air filter as well.;)
who did you talk to that thought it was? Lol
So it’s an insulant
🛻👍🏼🚚
I have put it on connectors for decades without problem. Generally, avoid metal to metal contacts but all around do. Many times, I put it metal at metal without problem. There are explanations on the Internet that when you put dielectric grease in contact it goes in walleyes of metals.
This video could have been a trip to the dictionary and looking up the definition of "dielectric"
I guess the tutorial here should be about using a dictionary, not a particular product.
Go look up the definition of dielectric on Wikipedia like I did, this is like a dare, I need Wikipedia for dummies.
Dielectric is an annoying prefix kinda like inflatable
I Just to add that.i had been using permatex dielectric grease on ignition coils every time I bought one !!well and when came to starting they would just Crank !!well. My first thought would be to Blame the Coil makers! and Today I replaced my second coil and greased it and wouldn't Start!!! so I went bought another and DID NOT PUT ANY Dielectric grease and the car Started Perfectly All. I can say its a Mistake !! the manufacturers ARE HIDING SOMETHING OR ELSE PROVE IT OTHERWISE!!!!
Well I guess it makes sense
Die = Energy gone, Lifeless, Your bank account after taxes
Electric = That stuff The Flash uses in the movie that gives you energy, gives Life, what the IRS hunts you for
So if I combine those two together *Keanu Reaves Moment*
