correct type of grease for sealing electrical connections from water damage?

 

dielectric

 

Di-electric grease. You can get one-time use packets at any parts store. It's predominantly to prevent corrosion on connectors, rather than to prevent water damage, but it works for that, to a point.

 

yea thats what i was referring to. corrosion mainly...

 

please don't use any RTV or silicone, lol

 

FYI...

Dielectric grease is usually silicone based. It can also be used on disc brakes and to recondition old rubber components(i.e. weatherstripping).

 

You can usually find packets of the dielectric grease right at the counter of your local parts store.

 

yea i know what you guys are talking about. i work at my local parts store.

who uses silicone for that??? lol..
i could understand using silicone if you werent planning to disturb the connection again...

 

you know what I meant

 

Dielectric grease is generally non-conductive and used primarily for excluding moisture. Because it's non-conductive you have to make sure any physical / mechanical electrical connections are clean and secure.
Alternatives to dielectric, if you're worried about corrosion, are anti-sieze lubricant and dissimilar metal coatings like NoAlox, KopperKote, etc., sold in the electrical department at many hardware stores. You have to be careful with them though since they are conductive and if used on a multi-conductor connector can cause shorts between terminals.
