Dielectric grease

[kasey54 305]

Good morning Ladies and gents. I have to replace a couple of leads and terminal ends on a commando.

 I'm thinking about dialectric grease or paste , and wonder whats recommended. Wondering also if its good stuff for 

fuse holders and pin connectors. Any suggested brands , do's don'ts ,or general advice. Thanks!

I use dielectric grease on all electrical connections including batteries.

absolutely use dielectric grease an all your electrical contact areas . i use the SUPER LUBE  squeeze tube type , i also added another battery cable ground from engine mounting bolt / frame to battery grounding area ,with dielectric grease. found that to eliminate any issue , and added that cable to all 3 of my horses. pete

OK, I know what the stuff is and have been using it as its recommended so many times in many connections. I just finished doing a COP/spark plug change on my 06 F150 5.4 (that was FUN!!) and of course lots of use for the grease there. But .... I dont really understand how/why/what a grease can be of help in a conx??? It looks and feels like many other petroleum greases in a tube but they sure arent for lectrics.

I second an interesting a brief explanation of how it works differently then other greases...

The major difference is that the dielectric comes in a tiny tube and chassis grease comes in a very large tube for the same price. 

 

Of course the chassis grease may not be suitable for some connections.

 

Deoxit may offer better protection between contact surfaces, and grease will help seal out water.

I suspect the difference in dialectic grease Is the base material that is added to the oil. Most if not all pure petroleum oils are dielectric. Buy greases have bade materials such as clay, soaps, etc that could be conductive

Dielectric grease is silicone-based product that is NOT electrically conductive and will not mix with water. It is a non-curing product that will remain flexible and will not harden so it will continue to seal out moisture and oxygen eliminating the potential for corrosion.
