MG Chemicals 8481-1 Premium Carbon Conductive Grease, 85mL Tube, Black

Relatively expensive, but does what it says. You only get what you pay for. This grease goes a long way too. You only need a very thin coating.

Bachmann split-chassis? Enough in this tube to lubricate hundreds of locomotives and ensure electrical continuity. Does not seem to affect the nylon bushings or other plastic. Black grease. Perfect.

I had a problem with my button batteries losing connectivity before the had run down. These were those used out of doors or in a steamy kitchen. (Wireless bell push, dog rouge light etc.) The batteries continue working much longer since I used the tiniest smear of this grease to improve the connectivity. (I’m talking years longer)

Decent size tube, comes with a nozzle although I chose not to use that as the product is very messy and I only wanted to apply a very small quantity to circuit board contact pins. Product is black so needs care when handling to avoid staining. The product is very good and provides lubrication while also improving the electrical connection. It does exactly what it says, perfect.

It’s a carbon conductive grease and em proved the contacts on my Ebikes

You get a lot in the tube. But only need tiny amounts.

This is very messy so only use as a last resource. I put some on some paper and put in my multi-meter probes and the resistance was higher than expected.

Works well
