Things to Consider Before Buying

Going into the market without knowing much about the dielectric grease can be problematic, and you are unlikely to choose the right product. So, to prepare you fully, we are going to talk about the factors you need to consider before making a purchase.

Applicator

The grease might be of top quality. But if the applicator isn’t the same, there would be hassles during the work. Many often, we see unhappy users of a particular product only because the applicator isn’t nicely made.

A good applicator should apply the grease in the right proportion and amount. And it should be easy to use. Also, when it gets greasy, it should be easy to clean.

Some applicator brushes come with bending ability. This way, they can reach to the corners inside the container of the grease. Check out if the applicator in your chosen product has this feature.

Zero Voltage Leakage

Yes, there shouldn’t be any voltage leakage. We mean, the whole point of using the grease around an electrical connection is to seal it. So, what good a grease will do, if it leaks voltage? So, make sure that the grease will act as an efficient sealant. This way, the money will be worthily spent.

Handling Extreme Temperature

You want the grease to be a good heat insulator. Therefore, it should withstand high temperatures perfectly. Otherwise, you will find it to melt in no time.

Dielectric Grease vs Vaseline

Dielectric Grease vs Vaseline

So what are the differences between dielectric grease and vaseline (paid link)? Though these two things differ on a lot of things, people get confused so very often. Everyone knows that the Vaseline is purely a petroleum jelly.

We use it as a moisturizer in dry weather. However, that’s not all it has to offer. You will find it to be a very good lubricator, as well.

Yes, you can use it for lubricating plastics. Also, it can coat wood. Moreover, it acts as an insulator fighting off the dirt and salt. So, you can see why people get confused and fail to distinguish between Vaseline and dielectric grease. But, there are some differences between them.

Firstly, dielectric grease doesn’t conduct electricity. So, we see it being used around an electrical connection and acting as a sealant. On the other hand, Vaseline is conductive and, therefore, isn’t used in such applications.

Dielectric grease doesn’t melt even if there’s an extremely high temperature. But, Vaseline will get burned or melted down easily when the heat is applied.  Thus, the stronger formula among the two is dielectric grease.

So, if you want the best result out of lubrication, you should choose dielectric grease to be the lubricator, not Vaseline. For, it’s specially made for serving the purpose.

Dielectric Grease vs Silicone Grease

 Dielectric Grease vs Silicone Grease

If you think that silicone grease (paid link) is the same as dielectric grease, you would be wrong, but excused. For, silicone oil is used as an ingredient while making dielectric grease. So, it’s expected to get confused. However, there are a lot of differences between them.

For instance, dielectric grease is non-conductive to electricity. Therefore, it’s used to seal the connections and prevent any corrosion. Thanks to its high withstanding capacity of heat, it won’t melt or burn. So, this type of grease is very much useful in electrical applications.

On the other hand, silicone grease is mainly used for marine jobs, since it’s highly resistant to water. Now, if you expect it to withstand heat like dielectric grease, then you will surely be disappointed. But, if you have rubber to lubricate, you are game. For, it will do the job perfectly.

Now, since dielectric grease is made to serve more serious purposes, it comes pricier than silicone grease.

There’s another difference between them. While dielectric grease is non-conductive to electricity, silicone grease is also the same. But, unlike dielectric grease, silicone will cure into any hard form.

Bulb Grease vs Dielectric Grease

Bulb Grease vs Dielectric Grease

While dielectric grease is useful in many applications, bulb grease (paid link) does a particular type of job only. It’s limited to lubricating the bulb only. Yes, it isn’t nearly as versatile as dielectric grease. Besides, you don’t use it as frequently as you use the dielectric one.

Whenever the bulb is prone to corrosion, you must apply some bulb grease on it. That will prevent corrosion. Now, professionals like to use the grease only when there’s corrosion on the terminals. Otherwise, they prefer to use dielectric grease.

Now, dielectric grease can also serve the purpose of bulb grease. And that’s why we see such limited use of bulb grease these days. And it’s only expected since the dielectric grease brings about so much versatility.

I mean, when you can use a single type of grease to get many jobs done, why buy all those different types of grease, right? Now, when it comes to heat insulation, bulb grease might not be as wonderful an option as dielectric grease. Its heat withstanding capacity isn’t anywhere near the dielectric formula.

Dielectric Grease Substitute / Alternative

Although there are lots of dissimilarities between dielectric grease and Vaseline, you can still use Vaseline in a couple of applications. If you want to coat wood, it can be a good option. Also, it will be brilliant in lubricating plastic. And it can keep dirt and salt away, but not as efficiently as dielectric grease.

Another option can be bulb grease. But, it will be of limited use. It will serve the purpose only if it’s a battery terminal or tail light. But, it won’t insulate heat as greatly as dielectric grease.

Then there’s the third alternative, which is silicone grease. This thing will do an excellent job when you want to deal with the rubber. But, do not use it when you need the grease to be pliable. For, it easily cures to a solid form.

Now, dielectric grease is the best option for most of the jobs. We would suggest that you stick to it unless you must choose any other option. For, it will be difficult to find a proper alternative to it, as you can see. So, you better not think about using other types of grease only to save a few bucks. That won’t be wise.

Frequently Asked Questions

#1. What is Dielectric Grease? 

Answer: Dielectric grease explained here with uses.

#2. Is dielectric grease conductive?

Answer: No, it’s not conductive. And that’s the whole point, right? See, if it was conductive, then people wouldn’t use it as a sealant on any electrical connection. And not only it’s a sealant, but also it acts as an insulator. And that’s why you see it prevent corrosion so efficiently.

When you apply the formula on an electrical connection, it prevents melting. As we saw in our reviews, this thing can withstand extremely high temperatures like crazy.

#3. Is dielectric grease necessary?

Yes, it’s very much necessary. When you have a battery terminal prone to corrosion, you badly need dielectric grease. The formula will then make sure that the terminal is nicely protected from any unwanted build-up.

Also, it comes in handy to protect plastic, rubber, and other types of materials. It doesn’t let the spark plug get contaminated too. Therefore, when something so easily accessible and affordable can bring about so much benefit, you need to buy it; period.

#4. What is dielectric grease made of?

Answer: The grease has another name to it. It’s called silicone grease at times, though they are not the same. The reason behind the naming is that silicone oil is used in making the formula. You have the polydimethylsiloxane very commonly used as the oil.

Also, it contains a thickener. And we see it in the form of amorphous fumed silica most of the time.

#5. When to use dielectric grease?

Answer: You should use dielectric grease whenever the spark plug is prone to corrosion. If you apply the grease around that plug, it will serve the purpose as a nice sealant.

As far as marine applications go, you need to apply the grease when the gaskets are likely to be damaged by water and corrosion. It will prevent any such happening. And if there’s a chance of contamination around the electrical connections, you need to use the grease to prevent it.

#6. Where to use dielectric grease?

You can use it around any electrical connection to prevent melting and corrosion. Since the formula can withstand very high temperatures, it will act as an insulator all too efficiently. People also use it for protecting spark plugs from getting damaged by materials.

We’ve seen it be widely used in marine applications too. For, it prevents corrosion like nothing else. It also goes well with rubber and plastic.

Final Words

It’s time we wrapped up our best dielectric grease reviews. Now, do not hesitate to go for any of the reviewed products. For, each one of them is one of a kind when it comes to sealing, lubricating, and insulating.
