Loctite Bulb, Lamp, and Electrical Connection Dielectric Grease - 0.33-Oz Tube - LT37534

Average Customer Rating:  4.8 out of 5 stars   (111 Customer Reviews)


by:

Thought I had a bad wire but it turned out it was some water and crud in the connector. Grease fixed it. Keep it in my trailer tool box.




by:

Bailey was more knowledgeable than the manufacturer of the parts I purchased. The order was shipped out the same day. Spectacular service to say the least!




by:

This dielectric grease is great for making permanent outdoor wiring connections. It does a great job at helping fight rust and corrosion. Used on the attaching metal parts in combination with electrical tape on the outside of the parts, it really keeps the parts working for many years into the future. I also use it on the vehicle side of trailer wiring to ensure proper connections to avoid lighting failure while heading down the road with a trailer. Just add some when necessary to keep it covered and it helps a lot.




by:

Does what it is supposed to do. Working great




by: 06/01/2021

Exactly what I needed to rewire a 20-year-old trailer that was starting to show it's age with inconsistent lighting performance and continuity issues. In addition to purchasing this lighting harness, I upgraded all my incandescent bulb side markers and taillights with LED units and complete rewired the trailer. etrailer had everything I needed in one place with excellent pricing and superb service. Everything is working great and I love the brightness and visibility of the LED lights.




by:

A little tube of dielectric grease - works as it should: smear it on the electrical terminals of the trailer's electrical connector (or in any other automotive electrical contact that you want to protect from the elements) and it helps keep moisture and corrosion at bay . Grease is, by its nature, a tad messy - but this product works well for its intended purpose.




by:

it's good have used this stuff before




by:

I bought a small tube of dielectric grease back in the '70's when I lived in Iowa. All the humidity and winter-time salt on the roads caused many shorts in the electrical connections of older vehicles (1969 Camaro).

I've lived in Arizona since the late 80's, but my tube was about empty and I saw this on your website (plus I needed an item or two to get free shipping!). What little is in my old tube now resides in the electrical toolbox.

Five stars for etrailer!




by:

Used it on new T-One Vehicle Wiring Harness 4-Pole Flat Trailer Connector once installed, and will use it for vehicle and trailer light bulbs and other electrical connections. Good product.




by:

Product assembled as expected, less the metal bracket that doesn't assemble to the frame without partially removing the bumper. I chose not to mess with the bumper and directly mounted the unit to the bumper as others have done. Other than attempting to attach the bracket to the frame without luck, the assembly only took 20 minutes.




by:

Very knowledgeable, extremely friendly and helpful. I would give eight stars if I could




by:

It is dialectic grease. It is loctite brand. What more can you ask for.


Comments
One year later and no corrosion in any connector or light socket.
James B - 05/20/2019


by:

I haven't opened this one as yet. I've been using the dielectric grease that came with the four flat connection. I plan to keep the connections clean and apply additional grease as needed.




by:

Installed fine on my 05 Hyundai Santa Fe. Watching both videos helped with the installation. I also was sure to use the Loctite dielectric grease.




by:

Perfect fit and the right wiring connection for my Karavan trailer




by:

Dielectric grease is a must in order to have solid connections. Even if you live in a drier climate, you need this.




by:

Is great experience courteous sales personnel Able answer all questions




by:

These worked well on a Featherlite 8127 trailer




by:

I am completely satisfied. The package arrived quickly and I was able to install on my truck the same day with help from the installation videos. I will definitely purchase from etrailer.com in the future. I have saved money by spending with etrailer.com and doing the upgrades myself.




by:

Great. High quality manufacturing and does exactly what is needed, at reasonable price.




by:

Dielectric grease to help my trailer connectors. Works great!




by:

Typical tube of Dielectric Grease,works well.




by:

etrailer ROCKS! great service, great products, and the customer service is the best! They make sure your purchasing the correct product for your project the first time.




by:

Easy to apply, came to me quickly, and working well for my trailer lights.

  • Trailer Brakes on Airstream Trailer are Weak Even After Adjusting Them
    Usually when the brakes start to get weak it is because they need to be adjusted. If you had them adjusted and the problem persists it could be a problem with the brake magnets. First, you can visually inspect the magnets and if you can see the windings coming through they will need to be replaced. To further test the magnets you can follow the help article I have linked. Inspect the wiring to the trailer brakes, the magnet ground wires, and the trailer connectors on truck and trailer....

  • Electric RV Steps Vibrate When Closing After Installing New Motor
    I am not sure what model steps or motor you currently have, but there are a few reasons why there might be some vibration when closing the step. The first thing I recommend doing is making sure the new motor is mounted in such a way that it is making proper and secure contact with the gear plate, which is what will provide a ground connection. A weak ground connection can lead to the vibration and otherwise less than ideal motor operation for the step assembly. Also make sure that the...

  • Trailer Wiring Harness 118624 Only Plugs Half Way Onto a 2013 Land Rover Evoque
    Is there room for the connector on # 118624 to go on any further or does it stop half way? It will be a tight fit and it might take a little more muscle to fully seat the 2 connectors. You could use some dielectric grease, # LT37534, on the connections and it could make sliding it on easier and provide moisture protection.

  • Will Tow Ready Adapter w/ Lamp-Out Sensor Bypass # 20142 Work on 2005 Land Rover LR3
    The Tow Ready Adapter # 20142 is intended to work on a range of European import vehicles including your Land Rover LR3. It is not a vehicle brand-specific item. According to my contact at TowReady this item should operate as intended on your LR3 to prevent low-current draw LED trailer lighting from triggering bad bulb error messages on your LR3's dash display. My contact has had no reports of issues with this item used in Land Rovers. Before installing this adapter it is suggested that...

  • Can the Tow Ready Wiring Harness part # 118258 be Installed on Outside of a 2007 Hyundai Santa Fe
    We have heard from several customers who have done exactly what you are considering and just installed the Tow Ready Wiring Harness part # 118258 on the outside of the vehicle so as to avoid removing interior pieces. It's not the recommended installation method that Tow Ready suggests but it should work fine. I would strongly recommend the use of dialectic grease for all of the connections to prevent corrosion. For that you would want part # LT37534.

  • 2011 Range Rover Sport Towing a Trailer with LED lighting
    The Tow-Ready trailer connector adapter # 20142 you referenced is designed to work on a range of European import vehicles. This adapter will prevent low current draw on your LED trailer lighting from triggering error messages on your Range Rover Sport dashboard display. Before installing this adapter it is suggested that you check that your trailer connector's contacts are clean and free or dirt or corrosion. You might also want to apply dielectric grease like # LT37534. I included a...

  • Is the 6-Pole Square Trailer Wiring Connector Kit Water Proof
    I wouldn't say that the 6-Pole Square Trailer Wiring Connector Kit # 37995 is water proof. It is weather resistant. If submerged for long enough water could still get to the pins. That is why we recommend using dielectric grease such as # LT37534 on electrical connections to repel moisture.

  • Troubleshooting Brake and Turn Signal Not Working on Trailer Hooked up to 2013 Yukon
    The fact that the trailer works fine on your Tacoma is good news because that allows you to rule out the possibility that the issue is on the trailer and allows you to focus on the connections with your Yukon. Just disconnect the plug from your trailer and use a circuit tester to see if the signals are getting to your plug. You will also want to check location 3 in the fuse panel under the hood, which is the left trailer stop and turn lamp fuse. If they are it might also be corrosion in...

  • Troubleshooting Brake Lights and Turn Signals on 2000 Ford Excursion With 7-Way
    Since everything worked when you hooked up your trailer to another vehicle we know the issue is with your 2000 Ford Excursion. The most likely issue is that you have a blown or missing fuse so check Fuse Location 13 in the Passenger Compartment Fuse Panel and replace as needed. I do recommend checking your owner's manual to confirm this is the location. You will also want to check your Excursion's plug for corrosion, which can be green or white in color. A build-up of corrosion can interfere...

  • How Many Volts Should Each Pin of 4-Way Get?
    On a 4-way connector such as the T-One Vehicle Wiring Harness # 118412 that fits your 2009 Toyota RAV4 each of the pins - end of the wires - should be getting 12 volts (except for the ground wire, of course). Since you mentioned corrosion I highly recommend using Dielectric Grease # LT37534 on your connector to help stop any future corrosion. I've added links to a pair of help articles on trailer wiring that you may also find useful.

  • Installing Dielectric Grease on 7-Way Plugs to Prevent Corrosion and Keep Electrical Connection
    Dielectric grease is basically just applied in a thin coating to the connector plug. You can use # 11755 or # LT37534 if you prefer a smaller amount. I've attached a video to assist. Just like the connection on the back, you can add this to the trailer pins on the front of the connector as well to keep moisture and debris out to prevent corrosion. I've attached an article to help as well.

  • Needing a Wiring Harness Adapter to Hook a 1997 Chevrolet 1500 Truck to Trailer Lights
    For your 1997 Chevrolet 1500 truck, I recommend the Hopkins Plug-In Simple Vehicle Wiring Harness, # 41125. This harness will quickly install on your vehicle using a simple T-connector to plug into your OEM wiring. You will not have to cut or splice into your existing wiring. I also recommend using dielectric grease, # LT37534, when installing this wiring harness. Just a apply a small amount in each of the harness's plug end prior to installation. The grease will help prevent electrical...

  • Troubleshooting a Possible Faulty Vehicle Wiring Harness for a 2008 Kia Sedona
    Sounds like the power converter on your T-One Vehicle Wiring Harness, # 118410, has shorted out and will need to be replaced. The converter is designed to divert the lighting signal when you turn on your lights or use the brakes or the turn signals on your Sedona. If these functions are not working properly, then the issue is in the converter box. Before you replace it you will want to inspect the wiring of your trailer to see if you can find anything that would cause the box to short...

  • Replacement Motor for Coach Steps Does Receive Power But Does Not Operate
    Since you have tested your Lippert Replacement Motor for RV Electric Sliding Steps # LC301695 directly at your battery and found it to operate properly the issue you're having is likely to be related to the RV's wiring. First, check that you have good ground connections for the motor at both ends of the RV's motor wiring. A loose connection, or the build up of dirt, grease or rust at the ground point could easily interfere with the electrical ground. This condition would still allow SOME...

    The Hopkins Custom Fit Vehicle Socket # HM40975 that you referenced is a combination 4-pole/7-way vehicle-side socket for use in the 2014 Nissan Pathfinder that is equipped with the factory tow package. This part plugs in to the vehicle's wiring using its round U.S. Car Connector that would currently be installed at the back of the factory 7-way. I have linked you to a video showing this item being installed in a different vehicle; although the truck is different the process will be the...
