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.

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.
About a year ago, I purchased a brake controller and parts to install a 7-pin trailer connector on my Ford Edge. The installation all went well and I used the Dielectric Grease to seal the wire connections at the connector. My four-star rating was given simply because I don't know if the grease is working as I hope it is. Time will tell more years down the road. As a side note, I made an additional bracket to enclose both connectors (4-pin & 7-Ping, see photo) to keep the 4-Pin connector from sliding out of place because it was only retained on three sides without my bracket.
etrailer video showed how using dielectric contact grease wold be most helpful to make the under bed electric connections as water resistant as possible. I would never have know about it unless I watched the video. Great advice. I am planning to refresh the grease every year.
Wayne B - 02/03/2021This 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.
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!
The connector on my 2010 Chevy was difficult to disconnect from the trailer connection. Now after using this grease. Its smooth and easy to connect and disconnect. Will buy again
Did not use. It was suggested on your company’s installation video, but DEFINITELY NOT NEEDED for installation.
Bruce - 08/24/2021Used GE dielectrics grease before. This seems to be not as thick. Make big hole so it comes out better. Seems to work. I use it for outdoor electrical connections. Especially batteries in lights and grill igniter.
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.
One year after install, and I've never experienced an electrical connection issue.
Items purchased, Draw-tite trailer hitch and Tekonsha wiring kit for our 2020 Equinox. This was my first encounter with etrailer, and I must say I was impressed. From the initial order placement, I knew where my order was while in route and exactly when it would arrive. I had previously watched the installation videos on both products and they could not have been clearer. Total time from opening boxes, to tools put away was less than 2 hours. All parts are of quality materials and fitment along with reasonable prices. While this may have been my first experience with etrailer, it certainly will not be my last. Thanks to all for making everything go smoothly.
Great product, works as expected. Sealed connections on rear trailer lights. Excellent customer service. Shipping progress information very clear.
I will never order a trailer hitch from a car dealer. Your videos made it so easy. Everything was what you said it would be, the delivery was even a day early. Thanks
Have purchased through this vendor before. Always happy with products and shipping speed. I have them saved in my phone and will continue to use them.
Just exactly what the trailer installer said to get and it worked perfectly!
Only thing I would change is to have heat shrink connector's instead of regular ones. I cut the cheap ones off and put water tight heat shrink ones on instead.
Used on my fifth wheel plug I installed and have had no problems with the connection. Also worked great on a connector I was having intermittent issues with. I would highly recommend this product.
Great trailer hitch for a great price! It was easy to install and after a year of towing with it, I've had zero problems. I like the way it looks as well, in fact I plan to order another one for our other vehicle this month!
BARRY B - 11/02/2020Excellent product for preventing corrosion of electrical connectors.
a new product for me. Was very easy to use, just squeeze out a small amount ro the electric joint you wish to seal then apply your connecter. I sold the pickup so I caNT TAKE PICTURES OF THE VARIOUS JOINTS IN THE BRAKE CONTERLLER LINE I USED THE Dekectric grease in, sorry.
Great Products delivered in a timely manner. This is my second order and exceeded my expectations
Outstanding products and informational website! Products shipped fast and the install was very easy with all of the information on the website, in the package and including the videos. Super company!
As usual E-trailer delivered a quality product in a timely manner.
Bought towing adaptors/wiring parts for a 2001 Dodge Durango (it came from the factory without a tow package) and a 2014 Honda Pilot (came from the factory with a receiver, and only half of the tow wiring harness). I knew a year ago I needed to get these two vehicles ready for a move we’ll be making from TN to SC using a trailer with electric brakes (by August of this year). You have the list of items I purchased. I finally got around to starting the projects. Just finished the 2014 Honda Pilot yesterday. The installation on the Pilot went somewhat well. I made one mistake (human error on my part) I put the 30 amp fuse from the T-one vehicle wiring harness #118265 in the wrong fuse box under the hood. Also, after installing the plug in wiring adapter for the electric brake controller #3070-P and the Prodigy P2, I discovered I had no power running to the brake controller. I didn’t know why. I happened by chance while reviewing the hundreds of customer feedback comments that I needed an additional 20 amp fuse under the hood in one of the fuse boxes in slot number 14, for e-trailer. It seems to work ok now for the Honda Pilot (going to hook up the trailer today for a trial run). I’ll be installing the other components on the 2001 Dodge Durango this week. E-Trailer dosn’t have a “How To” video for the 2001 Dodge Durango Sport without a towing package. Not looking forward to this install at all. A few years back, I did install a receiver and a 4-pin adapter wiring kit to my rear brake lights on this vehicle. I hope with the the Universal Kit #ETBC7 and the additional Prodigy P2 #90885 I bought from you guys I can get the Durango ready to tow the same electric brake trailer. I did find “Trailer Brake Controller Installation-2001 Dodge Ram-etrailer.com” that I hope will make this installation go ok. Will there be any additional fuses or other things that I will need for this vehicle? Thanks, Garry
Heather A - 07/10/2018I’ve bought from etrailer numerous times. Have had nothing but great service from them. I have recommended them many times. I recommend them today to someone that had just bought a toy hauler.
