Hi there, maintenance-oriented haulers today. Today we're going to be taking a look at Librimatic's Dielectric Contact Grease. So we've been experiencing some issues with our travel trailer here. When we plug in, sometimes our lights are working, sometimes they're not. It's a little bit finicky. If we jiggle the connector, it usually works.Most of the time, this is caused by poor contacts inside your connector and that's usually due to corrosion.
You can see here that this connector is actually got some corrosion on it. And the plastic's actually starting to deform because once you get this corrosion on here, it's possible that you can still have contact enough to eliminate your lights and operate your functions. But this corrosion is going to cause extra resistance here, which is going to cause it to build heat. And as it builds up heat, you can see the plastic's deformed due to the excessive heat that it's caused. And eventually over time, that heat is going to cause further damage and fretting onto our connectors here.
And eventually, it's going to get so bad that we're not even going to be able to fix it.So to get on top of this, before it gets that bad, we want to clean out all this corrosion and we want to seal it up to prevent it from happening again. And that's why we're going to be using the Dielectric Grease here. Now there's a lot of different ways you can clean out corrosion. Usually something acidic like vinegar and water mixture works great. Or you can just go to your automotive store and pick up electrical contact cleaner to clean it out.
You can also use a bristle brush to clean it out. But you do want to be careful when using any brushes down here because if you spread those contacts apart, you may spread them apart too far to where they're not going to touch onto the terminals once you plug it in and then you need to replace the pins, potentially the whole connector.So we're just going to spray our contact cleaner in here. And we're using this contact cleaner because it is a quick-dry contact solution. Because we don't want any moisture or anything left behind. This is designed to dry out very rapidly so we don't leave any moisture behind.So we use the contact cleaner.
We still got a little bit of corrosion in there. So we're going to take our bristle brush to clean that up. Now you'll notice I'm not sticking it down in there, we don't want to spread those terminals out. So we're just kind of rubbing it along the top to get that corrosion out of there. A toothbrush works very well as well, if you've got an old one laying around. But if you don't and you need a bristled rush, you can get one just like I got here at etrailer.com. And we're just trying to get all that out of there.Now that all of our contacts have been cleaned up, we're going to take the Dielectric Grease and we're going to apply it generously to all of our pins here. So we want to try to keep out any moisture from getting in there. And we're not just using any grease. We are using dielectric grease because dielectric grease is specifically designed for this application as it does not conduct electricity so we don't have to worry about any of our contacts shorting out between one another. And then it has the other properties that grease has where it coats up the surface and helps keep out moisture, sealing it all in. So now that we've got that done, we're ready to plug it in to our trailer and hit the road. And we don't need to clean any of this up, we can just leave it there. We're trying to seal out moisture and dirt.On the other side here on our truck, it's a good idea to clean these pins out as well. So we don't want to transfer any of the corrosion that may be on these or the other ones, back and forth. And we can also put the dielectric on these pins as well, to help further seal up and protect this side.Now that we've cleaned up each end and got them greased, we can go ahead and plug them together. Now we discussed earlier about how the grease is non-conductive because that's what we want. We don't want any of our pins to be shorting out with the other ones next to it. But that doesn't mean that it's going to cause any issues with the connections between our connector here on our trailer and the one on our truck, because the pins are designed to be a nice tight fit. So when it goes in, we do get metal to metal contact as it pushes that grease out of the way. Now it's when during cleaning, if you do stick something down in there, you can spread those terminals apart. And when you go together, they may not touch that because you have damaged pins. Now to replace the pins as long as everything's okay, our grease is not going to affect us because that terminal is going to have good contact.And it's not only great for the seven poles like we showed you earlier, but it's going to work on all of your trailer connectors, especially ones that are exposed to the elements like this. Keeping them coated is going to help keep corrosion off of them to ensure a longer lasting connection. So your four poles, your five poles, basically anything here on the outside. And it's also highly recommended for you flat towers out there. So your six pole ends and your seven pole where it plugs into your motor home. Keep those all greased up as well, because we don't want any connection issues with our vehicle when we're flat towing it down the road.And while you're at it, don't forget about the lights on your trailer. All these connection points as well are susceptible to corrosion so we can keep all of those clean. And if you have incandescent bulbs on your vehicle, it's recommended to put them on those as well.Pretty much any connector that does not have a weather pack seal, which has a rubberized seal around it. You would want to put this grease on because they have no form of weather protection. And that's what this is doing for us, is providing us with a coat of weather protection.All in all, this is going to be an inexpensive way to keep all of your electrical components operating properly and avoiding expensive wiring repairs down the road. And that completes our look at Lubrimatic's Dielectric Contact Grease.

Protect your electrical connections with this specialized formula that combats corrosion from water damage. Electrical Contact Grease comes in a 2 oz. tube.The dielectric grease is good . The mounting flange on the female plug broke as I was attaching it with screws. I think it could have been more substantial.
Ordered hitch receiver with wiring for bike rack installation on 2019 Ford Explorer. Everything arrived in less than a week. Crawled under the car with my burly son and finished the installation in about an hour. Toughest part was getting the exhaust hangers off. Didn't have a tool for that. Online installation video was a big help. Hitch frame rubs against right side exhaust hanger, hence the four star rating instead of five. Exhaust still appears to be level and no weird noises, so not an issue. Get the little plug in light tester. It's worth it, then keep it in the glove box. Haven't purchased bike rack yet, but no concerns about the hitch.
Bought this hitch along with the wiring harness and 4-pole mounting bracket. My mechanic installed and it's been working great! Hauling well anytime needed!!
Makes the electrical connections more reliable and keeps water out.
All items as described,Wiring was great plugged in and ready to go
The grease is something I don't think of sometimes too protect the electrical components. Easy to use tube, great spreading, not clumpy
My order came in great shape and in a very short period of time. This has been the case every time I have ordered something from etrailer. I am very happy with all the products I have purchased and the service is outstanding also
Great dielectric grease.
Just the right size (volume) for all the electrical work to install trailer brake controllers and lots of wiring in the Jeep and trailer. I prefer dielectric grease over a dab of silicon on wiring connections.
Use it for my RV toilet seal. Works gre at!!!
We just purchased a 2019 Hyundai Santa Fe as our retirement vehicle for traveling. We wanted to install cargo accessories but the dealer prices were WAY to high. After researching for several days we found etrailer.com. The prices were the best we found and the service was outstanding! We installed a Thule roof rack system that fits flawlessly and allows the panorama sun roof to plenty of roof to operate. The videos made in really easy to install. We also installed a trailer hitch system. The Tekonsha Trailer Wiring kit was also a piece of cake to install. If you're hesitant to work on electrical systems, there's no need to be afraid. It's actually easier than it looks in the video.
The Curt Trailer Hitch gave me major headaches. The delivery company banged the box up pretty badly. Apparently it tweaked the hitch just enough so that the holes were misaligned. No problem, after talking me through the installation one more time to be sure it was damaged, they shipped a new unit. The second hitch went in fine. It took a while, and it's not as easy as it looks in the video, but I'm 67 years old I did the installation myself...
Overall, I gave five stars because the price match guaranty makes it a wise choice price wise. he videos are a big help during installation. But the real difference is the service. A lot of folks provide good service to make a sale, but etrailer goes the extra distance to provide great service afterwards. That's unique! Thanks etrailer!
I always use Dielectric Grease on all electrical connections, Seems to work well.
This stuff really works to keep my tow vehicle and toad electrically connected. I used to spend a lot of time cleaning and redoing those troublesome electrical connections especially in wet weather. That is all behind me now. (Pun intended). The tube is strong to reside safely and conveniently in my tool box so it is readily available for future use.
Overall, the grease is fine, but the packaging sucks. The cap comes off too easily. By the time I realized it, it was too late.

Its in the garbage. Great size package and doesnt take up much room in a tool bag, but the cap just pulls off instead of screwing off. I replaced it with a different brand that has a cap that stays on.
Worked as it should. No issues!
When the wiring arrived I had high expectations. We installed it as per your instructions. I was very disappointed when we found out that it was too short. Had to cut and splice two wires. Not having to do that was a big selling point. What surprised me is a number of your reviews mentioned this and no corrections were made. They recommended cutting the small zip ties and that didn't work. For the records installation was made on a 2011 Jeep Grand Cherokee.
These bulbs work fine. They're a direct replacement for stock and are brighter than stock bulbs.
Product was fine, there was some conflicting shipping information that I was receiving. All in all, it worked out ok.
Good quantity of grease. I usually only get the small tubes at auto parts stores and they don't last long. This was big enough to actually apply all I felt like without worrying I would have enough.
What's there to say, I opened it up, applied it; hopefully it does its job.
I ordered the Mighty Cord 5th Wheel/gooseneck 7-way wiring harness for my 2018 Ram 3500. The installation was quick and easy. Thank you etrailer.com for the great products, fast shipping, and commitment to making my life easy.
You guys are great! Thanks for making everything so easy, every item I order always has a video for the same vehicle showing exactly step by step how to install. Before I found this website I way over paid someone to do all these jobs, now I feel like I could rebuild a car! My jeep is good to go, my truck is good now my wife’s car also is setup, so my next project is to replace a few brackets on my boat trailer! 100% satisfied
Quality product, reasonably priced, prompt shipping.
Amazing!! Fast delivery and no issued with items ordered. E- trailer is a great company!
Just received these items. Items arrived as seller advertised.

I renew the grease on the connections annually. It works great to keep them reliable in all sorts of bad weather, especially when you have to make hookups in the rain.
