Product Description
The 8481 Premium Carbon Conductive Grease is an electrically conductive grease with a synthetic oil base. This product is similar to the MG 846 silicone conductive grease, but unlike its silicone counterpart the 8481 synthetic-oil grease is essentially non-bleeding. Further, it includes corrosion inhibitors that provide superior corrosion resistance. The 8481 grease lubricates and improves electrical connections between sliding surfaces and parts, ensuring good grounding connection. It is also used to improve electrical continuity between irregular and pitted surfaces, as well as providing an economical way to protect switches against corrosion. Extends the life of contacts. Resistivity better than 400 Ω. Silicone Free. Safe on plastics.

Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers find the conductive grease works well and is useful for electrical maintenance. They appreciate its conductivity and corrosion resistance, with one customer noting it keeps metal connectors free from corrosion. The value for money receives mixed reviews, with some finding it fairly decent while others consider it expensive.

- Reviewed in the United States on January 11, 2024Number of Items: 1Verified PurchaseI use this for a connection from my truck to an inverter. The connector is exposed to the elements under the hood when the 8000 watt inverter is not hooked up to the truck.
This is extremely conductive grease. When using the inverter, I often pull 3-5 minute loads of over 500 amps and this grease keeps the connection good enough that it does not get hot. It is, IMO, as good as bare metal connections, with the added ability to keep the metal connectors corrosion free.
Good stuff. Kinda expensive but you use so little that a tube will likely last your lifetime, so it isn't that bad. It does wash off, you'll need to reapply about every 4-8 months.
All in all, it is a good product that does what it is supposed to do and a fairly decent value
- Reviewed in the United States on November 16, 2024Number of Items: 1Verified PurchaseAfter reading Guzzar’s review I bought to see if this could fix my Siemen’s circuit breakers (CB) overheating where the CB contacts onto the backplane tab. WORKED BEYOND EXPECTATION! Fixed two problem breakers that were overheating at tab contacts. Power off, clean backplane tab w fine sandpaper keeping debris out of box, thinly grease tab and new CB contacts, reinstall. I needed new CBs because old CB’s contacts arced. And it’s not the new CB, new CB in past still overheated but with this grease they run cool. One 100A breaker feeding garage was fine until I stressed it by charging newly bought electric car. With clean tabs, grease, and new CB it runs cold. Great stuff.

- Reviewed in the United States on October 12, 2020Number of Items: 1Verified PurchaseFeel like I have all new TVs. Just carefully pry open your remotes (I used a stiff, solid, stainless paint scraper and a medium flat screwdriver to pop open plastic.), then used 70% alcohol to wipe circuit board (did not wipe buttons), cut a toothpick in half and sanded it smooth and flat, then dobbed as little of this carbon compound on each button as possible while still completely covering each button's contact point. Even that was too much compound; and had to partially reassemble to press all buttons twice, then disassemble and re-wipe only the circuit board contact surfaces. First remote took 4 or 5 re-assemblies to remove excess carbon (never wiping the rubber button contacts, only the PCB contacts) subsequent remotes still took 3 re-assemblies and wipe clean so that no buttons were activated all the time by excess carbon grease. Did all five of "bad" remotes in 3 hours while being distracted by simultaneously watching football on TV. Very happy! Now can fix my volume, channel, input, and recall buttons anytime they stop working correctly, which is usually about 12 to 18 months between remote control failures on my Sonys and Samsungs. (Got a Pioneer Theater remote control that has never failed in 8 years, go figure.)
- Reviewed in the United States on May 23, 2017Number of Items: 1Verified PurchaseI've not used all of this grease, but so far it seems to be working as advertised. The only issued I have seen is that when acquired it was leaking from the end of the tube, and somehow sometimes from the cap. I cleaned it a couple of times and I have not seen this again.
- Reviewed in the United States on September 8, 2024Number of Items: 1Verified PurchaseHelped fix an intermittent connection issue with a bulb plug. Be careful, it gets EVERYWHERE.
- Reviewed in the United States on May 26, 2024Number of Items: 1Verified PurchaseImproved connectivity and made plug slide in and out of wall plug much better.
- Reviewed in the United States on August 7, 2021Number of Items: 1Verified PurchaseIt was black, thick, and slick and I presume conductive due to the black carbon in it. Only time will tell if it does an adequate job of lubrication on the switch points of my welder. The carbon in the grease is supposed to minimize electrical arcing of the points when they are switched. Again, only time will tell if it is effective in doing that. So it is really too early to make an adequate evaluation of this product.

5.0 out of 5 stars Messy But Useful Grease
Number of Items: 1Verified PurchaseAs the title eludes to, this grease is messy stuff. I highly suggest wearing disposable gloves and using the dispensing tip that comes in the package with the tube of grease itself as you don't need much of this grease to thoroughly coat anything you need to use this on. I mostly use it to coat ground connection points on vehicles since this grease doesn't wash away easily and is electrically conductive, so it prevents corrosion and ensures a solid connection will be present for the forseeable future.
You could use it on electrical connectors/terminals as well, but then you'll need to be very precise in your application of this grease as again, it's electrically conductive, so any stray grease could potentially bridge connections and cause much bigger issues. But as long as you keep this products attributes in mind while using it, it's a fantastic product to have around and the tube is big enough and you need so little at a time that this tube should last you for many years.
