Default Dielectric Grease

Yay or nay on applying dielectric grease to relay connectors? Thanks.

decide for yourself -

BTW - this is my personal choice for di-electric grease.

I think its a good idea. It helps the contacts resist corrosion and promotes current flow so I say yes to it. Just a little bit is needed so no need to glob it on.

Also use it on weatherstripping.

YES. Although technically an insulator, it prevents the contacts from oxidation and thus suppresses the formation of carbon residue due to arcing.

It also provides some lubrication, and as We Gone points out, it is a fair weatherstripping protectant, especially in Weatherpak (connector) seals, etc.

It's good stuff!

Di-electric grease is essentially silicone paste. Silicone paste has lots of uses as a lubricant (brake slides, spark plug boots, weather
strips, etc.. and insulator and many times costs less the di-electric grease. Di-electric some how means a 2 oz tube costs more than a 6 oz tube of silicone paste at the hardware store.

still working on an 8 oz. jar I bought back in the late 70's. good thing this stuff doesn't have a shelf life -

Have 2 large tubes that I've had at least that long, When we would replace an X-Ray tube they always sent a few large tubes for the high tension cables>

here's something I found on-line. you can take it FWIW...

Dielectric grease does not promote electric current. Quite the opposite, it resists current flow, i.e. it is electrically insulating.
Why anyone would put it on electrical connections of any kind is beyond me....if anything, I'd put electrically conductive grease on connectors.

"conductive grease on (multi-pin) connectors" -

you are correct, and (no flames) also wrong at the same time. I think we're getting off track here on the use of di-electric grease and the terminology. pretty sure the OP is saying on "electrical connectors," meaning, to use as a (weather) protective sealant on multi-pin connections (multi-pin - keyword)- at least that's the way I read it. on a multi-pin connector, you would not want to use a conductive grease as a sealant. for example, on a multi-pin light bulb, like a parking light/brake light/turn signal bulb that's exposed to the elements. you would want to weather-proof and lubricate the connection without adding a conductive path. the general's been doing this for years, and I think the general's been using di-electric grease on various under-hood relay connectors - at least on my C4. i'm trying to think of the havoc the OP would have if using conductive grease on a 4-pin relay connector - di-electric grease is typically used to weather-proof and lubricate the connection and protect it from the elements and not as a conductive aid - unless MY thinking is wrong.

Oh yes. It's not just weather, it also helps keep oxygen etc from corroding the pins, prevents any movement from rubbing metal away and brings little angels to watch over the wires.

I've got two tubes of DC4 for the same purpose. You're not the only one with an A&P here.

I put dielectric grease to kind of weatherproof my connectors an they last longer between cleanings that way. I am not sure of the science factor
