Actually, dielectric is an insulator. Look up the definition....

But di-electric grease IS an insulator.... It only works good because putting plugs or lights back in pushes out the di-electric grease in between the contacts so electricity can flow but the rest of the contact is still protected from air and moisture by the grease.

Dielectric grease does not conduct electricity. It seals surfaces against corrosion and prevents bonding between parts. The pressure of metal-to-metal connections is sufficient to push the grease out of the way to make contact and electric flow resulting in the connection being encased in grease, keeping water and corrosive elements away.

Do you know what dielectric means??

@3:05 Dielectric actually means having properties of an insulator. Who is the idiot there? He-he-he.

Where's the actual comparison between the two greases? He just said he's used both. That's it. First half was the man ranting about how much experience he has and calling a man an idiot because he said dielectric grease is an insulator which IT IS (3:00). And the second half was basically again ramblings of whatever how many jobs he's done plus an infomercial of his own product. What's the purpose of this video?

The stuff in the green metal tube (DC-111) is one of the best silicon based compounds for electrical connections I have used. We bought it by the case in grease gun sized tubes for use in the oilfield on downhole 5/16 electric wireline operations. it held up in 150*C temperatures and to hydrostatic pressure rated from 10,000 - 15.000 psi. Its also an amazing ring sealant/lube.

According to the dictionary: dielectric = a medium or substance that transmits electric force without conduction; an insulator. In electromagnetism, a dielectric (or dielectric material or dielectric medium) is an electrical insulator that can be polarized by an applied electric field. When a dielectric material is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor.

Probably a task for Project Farm!

Thank you! I’m convinced that I got exactly what I hoped to get, which was confirmation that I can use white lithium inside an auto electric switch in the absence of dielectric grease.

dielectric, insulating material or a very poor conductor of electric current just saying , now that does not mean that dielectric grease will hurt the connection in any way.

I love that quick orchestra music at the beginning!

I disagree with the argument from authority. I know its annoying, but its a logical fallacy. Expertise should make it easier for you to explain things, it is not some sort of permit to refuse questions.

Maybe you misspoke? Dielectric does in fact mean "resistant to" electrical conductivity. Which is the same thing as saying insulator. I'm not saying it will prevent contact. I'm not even saying don't use it. I'm just pointing out that it is an insulator.

ahh,not for nothing,but you never touched upon the title of your video,which was about the differences between the 2 types of grease,which is why i watched the video,the on;y thing we learned is you seem to have done many lighting jobs and are fond of lawn lights,lol

Pretty much all grease has low conductance so technically, they can be used to stop moisture ingress. The reason they say to use silicone/dielectric grease is because unlike petroleum grease products, it won't eat away at plastic insulation. I have seen petroleum products like wd40 melt plastic over time. Silicone is also very good with heat so it makes the perfect grease for use with electrical connections.

Thanks for the video and the info.

Thanks for sharing sir. Been wondering if the spray white lithium grease would work, but the CRC is pretty thin stuff. I'll keep my eyes open for the thick stuff like yers. Take care from Tn.

I just tried to measure the resistance of some dielectric grease and it did not conduct.

The term dielectric was coined by William Whewell (from dia- + electric) in response to a request from Michael Faraday.[5][6] A perfect dielectric is a material with zero electrical conductivity (cf. perfect conductor),[7] thus exhibiting only a displacement current; therefore it stores and returns electrical energy as if it were an ideal capacitor.

I used a spray in lithium grease on my motorcycle parts. That should work right?

I am connecting batteries for solar and looking for longevity. Which grease should I use?

Hello.. so instead of use dielectric grease in the ignition coils cars can I use white lithium grease in spray or have to be the gel one. If yes!?.

Could this be used on a electric battery charger port for a bike? I have corrosion I'm trying to get rid of . It is a lithium ion battery though .

There are two important things when hiring someone for a job. 1) Experience (number of years and how many jobs done). 2) Willingness to do the job YOU want, not to do the job HE/SHE wants to do.

1982 automotive school graduate here. I've witnessed that White lithium grease does turn to a hard dried mud after many many years making it difficult to remove old bulbs on old cars. Also, 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. Only apply around the connection not where the metal connects to weather proof and to make easier dismantling in the future.

Can I use White Lithium Grease on my motorcycle headlight Kit which is an aftermarket consisting of a fan to cool the bulb and is partially exposed behind the headlight fairing?

How often do you think this guy actually went back to check his old work years later? It's kind of a weird concept for empirical testing, I did something but didn't check the results 90% of the time. I think we need to get project farm installed.

I was looking for specific grease that use on steering column boots and rubber bushings. Lithium vs dielectric grease really confuse me.

I have issues with hvac condenser disconnects (the stab in kind) do you think white lithium grease work on this?

Dielectric grease is an insulator. This means Non-conductive... That's the definition of dielectric. It is great to prevent sticking in high heat or corrosive environments. Who am I... just a guy who took Automotive Electrical Repair at the Bill Shaw Vocational Technical School. That doesn't mean I know it all, but this is a common misconception that has plagued many people when the fill their plugs full of grease and can't figure out why they have intermittent electrical current or reduced current flow (HIGH Resistance) due to the grease preventing a good connection. It's meant to go on spark plug boots, and connector seals, not on the contacts directly... Hope This helps.

You're a straight shooter, thank you! I've used White Lithium for decades too, mostly for machine electrical applications. Thanks again, Alex C. (FAA licenced aircraft mechanic (A&P), and Industrial Engineer.

The NEC does not require Nolaox unless the manufacturer calls for it as part of the instructions. See 110.3b. 110.3b could also prohibit certain chemicals. For example, an anti-oxidant containing grit used on a conductor cannot be on the lug threads, since that prevents getting a reliable torque value.

Dielectric grease can be used sparingly on connectors. Microscopically, the metals have pitting. The grease fills in those small valleys and the metal to metal contact will push the remaining grease away. Using large globs of it can possibly create resistance which stresses the power source. That's my understanding.

Can you use plain old lithium grease or does it have to be white lithium grease

In my experience new college graduates automatically know more than those have experience. A supervisor told me about a skilled trade person tell him that he was ok because he knew how dumb he was. was mad then thought about it then starting it was meant as a compliment. He would listen and ask questions.

Had vehicles that came with white lithium grease and the bulbs seemed to last forever and have used dielectric grease for years with great success.

What’s the difference between white lithium grease and other colored grease that says it’s lithium based?

In 2008, i removed a relay from the engine bay of my 1990 Corolla. The terminals were coated in a mysterious grayish substance. I did not know what it was at the time but intuition told me it was to aid in corrosion resistance. I remember how beautiful the connections were, assuming that relay had been sitting there for 18 years exposed to the elements. White lithium grease is good stuff.

dielectric is used in small amounts on cars electrical parts. white lithium is usually sprayed to resist moisture and corrosion and for hinges. am i right?? lucas is good. crc is too.

I love that CRC bottle of dielectric grease on all my electrical contacts. I’ve redone a lot of fittings in my furnace. I used a light coat on all the contacts. I especially use this stuff on any dc connection in my truck. Works perfect and waterproofs. Your rationalization on lighting jobs and having someone tell you how to do your jobs reminds me of the public telling a cop how to do his job. I was an electrician for 8 years and now a cop. Great video!!

In the 70s my brother had a Oldsmobile beater car and when it snowed or slush rain the car would not run or start. His friend sprayed white lithium grease on the wiring harness plug at the firewall.. This immediately stopped the harness from shorting out and the car ran like a top ...

3:00 but I looked up "dielectric" and the definition is "a nonconducting substance; insulator", so... You tell me what it means.

Hi there.. I wonder if you could give me the benefit of your wealth of experience.. I have a pool light, and the cable enters the bottom of the light and connects directly to the 12Volt halogen bulb..The connections would be in water if it were not for a grease like substance packed around the connections and contained within a small plastic cover.. The 'grease' does not smell or look like auto grease..I have a clear close up photo if it's of benefit.. My question is, do you have any idea what that substance might be, or what could be used in its place?.. Thank you, and thank you for a great video.. John, Western Australia.

Any desent wheel bearing grease will do

White grease for car battery post?? Thanks

How do you know if it's night?

it would have helped had you shown how you apply the dielectric grease to your fixture...

Nothing beats experience. Thumbs up.

What parts do u recommend putting the dielectric grease on? Only the wires? Or also on the o-rings, any screws/threaded connections? Thanks!

Now I'm even more confused. I watched a vid earlier that said Dielectric Grease was an insulator and should be applied the rubber boots of spark plug leads and the ceramic sleeves of the plugs themselves to do two things; insulate to prevent over sparking to the body and as a grease to make taking the leads off easier. I've been told bulb grease is dielectric ~ meaning it does not conduct electricity, so it can be liberally applied to both the indicator bulb and the indicator bulb holder ~ to prevent corrosion [mine have corroded badly]. Are you saying that I can use white lithium grease as dielectric or bulb grease. ? I also ask because a tube in Amazon dot com is some $7 but in Amazon Co UK it's suddenly £70 Seventy Pounds ??????

Dielectric means to be an insulator. Per all the dictionaries and electric sites I looked up. I have a controls and electric licenced & certified lifetime background. Silicone grease and dielectric grease are not the same. kzfaq.info/get/bejne/sOCBoZZ9m7Kmj2g.html

"Ideal" has had a product that is a dark grease they call "joint compound". It seems similar to Oxgard or NoOx, not sure but it may have some zinc in it.

Good man. Thank you for the great video!

With you on the CRC grease! Have the same can siting on my desk as I watch this video.

Motor cycle had gobs of white grease Which seemed to dry up Royal Enfield had a complaint about the bikes quitting running until these areas were cleaned out

This proves that experience does not equal technical knowledge.

Could I use copper grease, and fuck everything up?

You should link the items in the description

With a to-do list like Ray's, I'm guessing he must be the new guy

I am lost. Is White Lithium Grease conductive or not? I think I messed up using it on my motorcycle key and the immobilizer fuse burned. Please someone answer if you know!

I love the CRC DEG

I've used Vaseline or a clear or translucent lithium grease on battery terminals since the 50's. In more recent years I've switched over to a silicon dielectric. I tend to avoid greases which contain a collodial dry lubricant such as graphite.MoS2, teflon, or talc as on the case of white lithium grease. The small particles of powder in suspension could create a resistance.

My problem with Lithium Grease: after cleaning the exposed door-latching mechanism on my 30 year old motor home I covered all exposed metal parts with Lithium Grease to prevent future rusting but within a few months noticed that rusting was accelerated instead of prevented. The thicker the grease, the greater the rusting.

Use a toothbrush to apply this stuff & keep the brush nearby. The toothbrush will get saturated, & sometimes you don't need much anyway. Yes sir.

As a marine electrician I carry both Dielectric and the other type that conducts electricity. The nylox? brand slips my mind, but is available at Home Depot

Is it white Lithium White Grease can be use for plastic gears ?

Bla bla bla. Went from a tech tip to a ramble and sales pitch. Can’t believe I listened this full video

I like using Burndy Penetrox Grease P8A Little expensive but good stuff.

Are there any odorless white lithium greases out there?

THANKS

Can i use white lithium grease to lubricate my clocks mainsprings?

I've used dielectric grease on the female 4 pin trailer connector on the back of my car including placing the cap over it and it still corroded in about a year's time. Ruined it. Got a new connector and I found this video trying to search for a different way. Why it corroded even with the grease on is beyond me.

What I learnt in this 10 & a half minute video - the dude has done 40 to 50 thousand lights and doesn't like other people's opinions. That's it - you could have said that in half a minute and save me the other 10 for learning elsewhere.

So... In conclusion, dielectric grease is not used on the electrical mating surfaces. It is applied to prevent voltage leaks by insulating the surrounding surfaces which is also why white lithium works just as well??? So which products would aid conductivity? Perhaps the same ones that prevent electrolysis between disimilar metals?

The problem with many dielectric greases is they are too low a viscosity, are meant for a light surface coating rather than void filling. Their lower solids to base silicone oil means that they do separate more easily than a more viscous silicone grease would. The problem with lithium grease is that it is not as temperature stable, will tend to melt and flow out of the area it is applied to if the connection creates a significant amount of heat. Granted, if you put these on a NEW installation and do it right, you aren't starting with heavily oxidized metal so there should not be much heat created, but the point is that the petroleum based lithium grease is not as good to use on already aged connections, unless you have the means to completely strip them down to a clean state again, which can be done with copper or brass but not with something nickle plated., then it is time to get a new connector if you want longest service life and grease performance.

What do I do if if i have a socket with oxidized connectors and i need the electricity to flow again in them? Can i just use any white lithium grease to get it working again? I can just use a paint brush and carefully coat the metal?

Field serviceable is also beneficial to the environment.

Dielectric grease is an insulating product. It doesn't conduct. So this man is incorrect about those products. Vaseline does the same. However, it works because the connectors scrape off the grease to allow conduction. At the same time these products do keep air and water out. There are youtube videos to illustrate how these product do not conduct.

As Wikipedia: Dielectric is an electrical insulator.

I use Dow vacuum chamber silicone grease. Of course then you must make sure that your fingers do not touch parts that you are going to paint. This causes FISHEYES! Same with Pledge furniture spray. How do I know this????????aarrggggggg

Why am I watching this video, 😒

WTF does the last 3/4 of this video have to do with grease?

I use conductive grease on the contact areas and di electric grease or silicone grease all around it, never have electrical issues and things seem to last way longer, even with the harsh winters we get here in canada.

I want to congratulate you on your success, and compliment the excellent design of your lights. My only complaint is the relevance to the title. Thank you for the video, and best of luck.

dielectric grease question , car mechanics say only put dielectric grease on the inner boot of the spark plug wire so it can insulate the porcelain part of the spark plug so no current can leak out and arc onto the metal areas surrounding the spark plug, also so that the spark plug wire boot wont stick to the spark plug and be near imposible to remove when doing a tune up , now my question is they also say not to apply any to the metal tip of the spark plug and the metal locking ring of the spark plug wire inside the boot because the dielectric grease wont allow the current to go from the wire to the spark plug ...is this true or false ..noone has ever answered me that question

Is white lithium conductive?

You summed it all up when you said ... to "Prevent Moisture Migration"👍

I wonder why you sir have not responded to any comments, have you figured it out yet that Dielectric Grease is not a conductor nor is it an insulator the only purpose for it is to coat the metal so that it does not corrode either by water, air or to keep it from electrolysis with dissimilar metals to keep them from fusing together. That about covers it.

A dielectric IS an insulator, but only for direct current. So that guy who you called an "idiot who doesn't know what dielectric means" wasn't necessarily wrong

Nate, the Lighting Bible looks good, but $75 ! Seems a bit steep.

My one takeaway from this video was to never use your business. Misinformation, ignorance and arrogance. No thanks.

Dielectric means it’s a insulator , you like it or not that’s a fact (if you were careful on physics class you would know it )

All dielectric materials can be insulators but become conductive when an electrical field is applied, not all insulators can be dielectric material however as electrons in dielectric materials are bound to the nucleus and thus possess very little movement. When external voltage is applied, the nucleus and the atoms get attracted to negative and positive sides respectively. Some insulators do not have this property to a meaningful degree which is why rubber and certain plastics are used as insulators only, capacitors have dielectric between the plates, coaxial cable depends on the dielectric properties between the conductor and the shield and thus have an impedance value that is designed into it by just this method. Jet fuel is used for it's dielectric qualities In the fuel quantity system on Jet aircraft, the fuel level probes of which there can be many throughout the fuel tanks, are just two plates (a small cylinder within a slightly larger cylinder with wires going to both plates just as any capacitor would have, with them fully submerged in jet fuel, the capacitance roughly doubles compared to the entire plates being dry (at least on some I have worked on in my Avionics career), this is purely because Jet Fuel is a much better dielectric than air. Xc (capacitive reactance) is used to take full advantage of this by applying a small amount of current to the probes (never enough to be an explosion hazard) making them act and measure like resistors. Xc is measured in ohms not farads obviously. Earlier systems used this capacitive reactance as a variable resistor leg in a bridge circuit and a servo motor driving an actual variable resistor to null the bridge and in doing so, moves the needle, calibration was needed periodically and mandatory when any part is changed, many a good tech was scared off when they heard of measuring in micro micro farads dubbed mickey mikes (non official term) and did not see the fact that they were merely dealing with a bridge circuit, a Wheatstone bridge to be exact. Modern jets have a computer that reads the change in Xc due to changes in dielectric as the fuel quality changes and then that gets sent to the displays via Graphics Generators where they are supposed to be seen. The moral of the story is that all dielectrics are insulators when not externally charged but not all insulators are dielectrics.

so silicon grase is good?

I've used CRC dialectic greas on Auto and Household. Never had a problem. 😒

good video but u side tracked me there for a bit

Dielectric means nonconductive bud. Might want to get your 15 years back

You are arguing about White Lithium Grease and the title says White Silicone grease. DiElectric grease is insulating from what I've learned.

great and expensive grease
