Dielectric Grease for Electrical Connectors, 2 oz.

My F150 had an OEM 4 pin trailer plug and hitch. The 118242 - 7 pin connector with wiring harness is the ticket. The hardest part of the install was dropping the spare tire. The plugs connect directly to the factory plugs and the harness length is the correct length. The 3035-P brake controller connector harness was just as easy. Plugs right in to the OEM plug next to the ECM connector and the other end into the brake controller. The PK12711U-26 - 7 pin bracket and hardware kit fastens directly the OEM bracket that is on the hitch. My truck had an OEM 4 pin trailer towing set up with the hitch. The OEM hitch had the bracket welded on it to attach the 7 pin mounting bracket to it. These kits make this install very easy and professional looking. If I have one complaint, the hardware kit to attach the 7 pin connector bracket is set up to fasten the bracket directly to the bumper with 2 - self tapping screws provided in the kit. The kit also includes 4 #12 machine screws with toothed washer nuts to attached the 7 pin connector to the bracket. This is fine if your truck hitch doesn't have an attaching bracket welded to it. The kit should included in it 6 #12 machine screws and nuts along with the 2 self tapping screws. Since my OEM hitch actually had a bracket welded to it to attach the 7 pin bracket to it, I had to use two other #12 screws and nuts to attach the 7 pin bracket to the OEM bracket on the hitch. Not a big deal, just a thought. It took me about 2 hours, start to finish to install the 7 pin connector, trailer controller, and add the two relays in the OEM relay/fuse box under the hood. I highly recommend these kits. 322337

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. 521602

It is always a pleasure doing a project that I source through etrailer.com. I bought the draw-tire hitch, wiring harness, and a couple of other things I needed for the install. Everything ordered was packed in a single shipment. It arrived earlier than expected and undamaged thanks to the care they take in packing the items. It all went into the car as described in their videos. I love the videos they produce and post to their site. They are such a help in both shopping and execution of the project. Thanks guys! Here’s a pic of the completed installation. 456190

Absolutely Superb Service! On the 23rd of September at 10:10 a.m., I ordered a brake controller and several other items from the etrailer.com website. By 12:16 p.m. of the same day, I received a notification from etrailer that the order had shipped. The complete order arrived at about noon on the 26th. Ordering on the website was easy. All items were described very clearly and pictures were provided for them. The service at etrailer is absolutely superb. I would recommend this company, without hesitation, to anyone needing trailer parts or accessories. 324674

Dielectric grease is the best lubricant for your electrical contacts on fuses, plugs, etc. Once the contact has been cleaned and dielectric grease applied the contact's will not corrode nor does it inhibit or degrade the flow of electricity thru the contacts. This grease is also very water resistant. This product is a full 2oz which is unusual as most auto supply shops etc. only carry the smaller, much smaller sizes.......and I alway's seem to run out. Etrailer was very quick with delivery of the product......as alway's. 28508

Being a new boat owner I was quickly overwhelmed by what I didn't know. Re-wiring, re-lighting my trailer was my first project. etrailer has a wide range of products, but most important to me, was their added product information and instructional information which helped me make the right selections to get this done. Add to that is their very competitive prices. etrailer will be my go to source for my future trailer needs. 313877

It came in a very nice, large tube. I apply it and it looked the same as like products . There is no reason to think it won't do the job. I will be putting this boat into salt water and even it that plug dose not go directly into the water ; it will be subjected to the mist, normal rain and road water. I will fllow up should it faail but I really don't expect that. Again thank you for the suggestion to use this, Joe Peek 329372

I recently purchased a 1998 vehicle and narrowed down a few electrical issues to corroded connectors. Cleaned them up, slathered this stuff on, and now the connections are not a problem and should be protected from further corrosion. I lubed up my trailer harness connectors and battery terminals on my vehicles too...should help in preventing the negative battery terminals from crusting up. 262742

This saves a lot of the headaches here in New Hampshire. Trailer plugs and lights are destroyed fast by road salt. Have caps on your plugs so dirt doesn't stick when not in use and so you don't get grease smeared on your leg. If you use crimp connectors, squirt some of this in before inserting the wire and then cover the outside with heat shrink tubing for a great weatherproof connection. 416664

All ordered items worked great. Love the LED tail lights. Didn't have any problems fixing the trailer thanks to the many technical articles I found on etrailer. Not sure what happened with UPS shipping since I got notified that the parts had shipped on Saturday but didn't get them till Wednesday evening (paid extra for 3 day shipping), but definitely recommend ordering from etrailer. 341396

by: John Colbert10/04/2016

Perfect product for my needs. I got a 7 pin 5th wheel wiring kit to put the trailer plug in the bed of my Ford 350. I also got dielectric grease, the kit came with some grease but I was afraid that it would be an insufficient amount, I was wrong but I can use it for other electrical attachments. Very pleased with the etrailer.com service, speed of shipping and customer attention. 303391

The t-one harness for my Mazda pu truck was just what I needed to haul a 4 point trailer.The transistion wire harness from a 4 point to a 7 point made it a lot easier to haul a trailer with a 7 point hookup.The installation was very easy for both.I have no doubt this way will solve easy hookup from 4 or 7 point hookup.I am well covered for either. 362771

by: Tom W07/18/2016

Does a great job of providing a good electrical connection. Especially important to use on all trailer connections to towing vehicle. 273336

Good product, glad I bought this with my trailer harness kit. Made a good contact on an otherwise old dirty connection. Now I'm putting it on other connection points to insulate the connector from weather and lube the fitting for easier disconnects. FYI this tube for the money goes a long way, use just enough to dab on the contacts. 325411

As a owner of a auto repair shop i have used this site to help customers find the right trailer hitch for there car and for me ones that are mostly bolt up to car and etrailer.com makes it easy for me the installer and the customer. as a busy shop in Briarcliff I always recommend etrailer.com excellent quality and workmanship 317838

Perfect and ideal. Too bad it don't come in a small 99 cent packet like auto zones bulb packets, because I'll never use this all. 304647

I have just completed purchase of complete system to tow a Jeep Wrangler with my motorhome.Never had I had the pleasure of working with a company so devoted to customer satisfaction. Every email and phone call was great. My wife was even more impressed. The service after the sale has been terrific Thanks Customer fo life 420268

by: Dr K04/26/2017

I've been looking for something like this for YEARS. I needed it for my brake controller install but also used it on a high-end computer speaker system where the DIN connectors didn't make good contact so it was always "noisy" expecially if the wire was touched. This conductive grease did the trick and quieted down the system. 372480

by: Joseph12/02/2017

Purchased this to help prevent corrosion on the 7-way plug on my new travel trailer and tow vehicle socket. Seems to work as expected as I have no evidence of any corrosion even with prolonged exposure to hurricane Harvey aftermath this year. There is enough in this tube to last a lifetime provided I don't lose it! 456529

by: Mike Pazsint07/08/2014

Great amount of grease for the price. Tips: Use the end cap on your 4-pin wiring connector to keep dirt and such from getting collected by the grease when the wiring harness is not in use. Also use a snack bag and rubber band to wrap the connector on your trailer when it is not in use to keep gunk out. 140125

So far so good. I ordered a bunch of stuff from several sites the night I got my brake parts. etrailer was the fastest order for fillment and the first on my porch by far. Everything fit like it was supposed to and this far seems to be working well. Can’t ask for more then that 516560

Keeps contact pins dry and corrosion free, eases connector insertion and extraction. Dielectric grease is essential for any wet wire tasks. I use this on all my electrical work. Ever have a plug extremely hard to pull out of a receptacle? Try some of this on pins and contacts. 452864

Really an amazing outfit. The web page provides all the detail needed to make the right choice on parts so its right the first time. The staff are friendly and caring and the delivery was spot on. etrailer is how web shopping ought to be done. They truly set the standard. 374921

I placed two orders with Madison in the last few weeks. She was pleasant, helpful and knowledgeable. She helped me select the right parts, and they all arrived in good condition before I expected them. I recommend this supplier, and hope I get Madison on my next call! 301490

by: Ron B.09/20/2012

I always use dielectric grease on all my plug connections to solve the corrosion problem. I live in Ohio and the salt on the ATV trailer does ruin cheaply done wiring connections. Worth the time and effort to not have to trouble shoot problems later in the wiring. 55251

by: freezer10/02/2011

I had three vehicles with hitches in the past that all had green 4 pole trailer connectors from corrosion. So far, this grease has kept that from happening. It is much easier to get the harnesses together and apart now, too. Well worth the money. 24958

by: Ryan C.11/20/2012

I used this product when installing a new trailer tap connection to the existing vehicle connection. I also use it on all my trailer connections to keep water out and eliminate corrosion. This is a very good product for this type of application. 59811

by: Lenny B.08/16/2013

Prompt deliver, accurate description, best price. Used the product on the lighting connections on my motorcycle and battery and starter terminals on the car. Not the clear dielectric grease I'm use to seeing, but it fits my needs perfectly. 95479

by: Curt B.06/07/2017

I've been using this product for many years. Put it on any electrical system to cut down on corrosion. I put it on Bulb sockets, Battery terminals, all of my R/V plugs and sockets. Works great. Thank you for another GREAT product etrailer!! 389994

by: HERBERT01/20/2014

I HAVE USED THIS PRODUCT BEFORE AND IT WORKS VERY WELL. I USE IT ON THE TRAILER ELECTRICAL CONNECTORS ON MY BOAT AND CAMPER. ALSO I COAT THE TRAILER LIGHT BULBS AT THEIR CONNECTION POINTS AND HAVE NEVER EXPERIENCED DIM OR BLINKING LIGHTS. 114279

by: Donald L.10/17/2017

This product is merely dielectric grease but necessary for protecting your electrical leads. I ordered it so I could avoid running back and forth to the store to pickup little additions to the installation of my brake controller. 443431

We are high end appliance repair company and use this product on some of our wall oven electrical connections. Great product and etrailer was a great company to deal with. Super quick shipping and availability of the product. 37573

Not much to tell - I used this grease for what is intended and just hope it does what it is supposed to do. All of my other purchases from "etrailer" were exactally as advertised so I tust that this will be the same. 122713

by: Ron G.09/13/2013

I use this product on my all electrical connections, on my RC helicopters, Harley Davidson, Car, and trailer. The order processing, shipping, and customer service at "etrailer" is the best by a country mile. 99872

i ordered several related products, one of which isn't available locally (7-wire molded trailer wire plug). as always, etrailer was fast and accurate with my order. i will certainly use this site often. 133102

Exactly what I needed etrailer had. Fast delivery everything I ordered was in great condition. Great service. Have ordered from etrailer several times, always on time and is exactly what was ordered. 302708

by: electrical grease09/14/2011

only had it for a few days, but it looks like electrical grease, seems to be otherwise OK - used it on the HONDA Element wiring kit and on quite a few connectors on my HONDA GOLDWING Gl1800 connectors 23968

by: Mark W07/30/2012

I've never used a product like this before, but I do notice that the wiring and plug connections on which I have used it are still shiny and clean. I am hopeful it will extend the life of my wiring. 49918

by: Luke H.03/03/2017

There are cheaper options out there but you get quite a bit of grease for the money. This is a must for new install of trailer lights/tow kit install and also a great preventive maintenance task. 347927

by: John M05/23/2014

Arrived on time. Put the trailer hitch and wiring on next morning without a hitch. Pun intended ! Etrailer your company is awesome! Will do business again for sure! Thanks for the great service. 132159

DIELECTRIC GREASE I HAVE NOT TRIED THIS TYPE OF PRODUCT BEFORE BUT FROM PAST EXPERIENCE I KNOW THAT TRUCK & TRAILER WIRING CONNECTIONS TAKE A BEATING. THIS SHOULD HELP KEEP OUT WATER & CORROSION. 4252

This item not only prevents oxidation of the contacts on your trailer plugs, allowing good electrical connection to be maintained at the plugs. It also allows ease of disconnecting the plugs. 434200

All items shipped and delivered a day sooner than the expected delivery date. The videos on the web site were a big help during my installation. I would order from etrailer.com again!!! 397993

Protects the electrical connectors from oxidation during storage and from water during usage. Only time will tell if it works as designed in the long run. But its exactly as desired. 437256

by: Ray B01/23/2017

Hard to say something bad about dielectric. It either works or it is yuck. It was nicely packaged and a nice addition to the trailer connections to keep them as clean as possible. 334664

I received my product in a timely manner. The product works very good. I've used it on several electrical connections such as vehicle tail lights and trailer lights. Works Great. 13581
