can i just use regular bearing grease??

[etrailertv]

@newt20002 Bearing grease wouldn't be effective. It's not designed for use with electrical connections.

doesn't protect from air - protects from moisture and other crappus either dissolved in atmospheric moisture or mechanically entrained (suspended) in air. What magnetic permeability of a substance is (in the presence of an applied magnetic field) - the permittivity of a substance is the electrical analogue .. the alignment of molecules to an applied electric field. It's a measure of the degree of electircal elasticity (ability to store energy) before snapping - i.e. breakdown voltage.

Cornellius: You are technically wrong. Any dictionary will tell you a dielectric is an insulator. It can be applied to connections to improve durability and performance by inhibiting corosion, but the grease itself is an insulator and is best applied AROUND connections to protect them. There are CONDUCTIVE greases that are better for INSIDE the connection, although with them you need to be careful none is outside the connection.

Who is right? The guy on the video says " basically it is a grease that conducts electricty". Read the video info.

If you dont know. Get a quarter coin amount of dielectric grease and test it with an ohmeter and see it yourself.

[mrdavester]

in my experience its NOT conductive, to my disapointment. I could see that it would short out connectors with close fitting pins if it did conduct.

Cornellius:

Please consider what is going to happen in a ScotchLok with a smear of conductive ANYthing in it...which is part of what the video talks about.

Before you argue something, DO try to inform yourself at least a bit. Look up the WORD 'dielectric' for starters. That would be good.

Dielectric grease is NOT conductive. Most popular use is in spark plug-plug wire boot relationship.

[Cornellius23]

It IS conductive, it's the main goal the the grease ! I use it all the time on battery terminals, they work great. Of course, if you don't want the terminals to short, don't grease them together.

[paulsubong]

The definition of "dielectric" is non conductive, insulator. Dielectric grease prevents corrosion on connections but it does not help with the conductivity of the connection.

[t100robert]

Wrong. Dielectric grease is NOT conductive. If it conducted it would short out the terminals. But the rest I agree with. Good video. Thanks. Bob.

[Cornellius23]

I'm an industrial electrician, but I use it (another brand thoug) now and then on my cars. Of course it is conductive, it's the main goal of the product ! A grease, that is conductive. If it wasn't, it would just be... grease.

[kyletaz]

if it was conductive and applied the way applied to the plugs in the video it would cause shorts, it was spread across all the connectors.

[Firepath]

Exactly - it's not conductive but the pins scrape the grease off as they contact, where they contact, keeping the surrounding grease there to protect them.

You should look up the word dielectric in the dictionary... a NONconductor.

Pronunciation: \ˌdī-ə-ˈlek-trik\

Function: noun

Etymology: dia- + electric

Date: 1837

: a nonconductor of direct electric current

Dielectric grease DOES NOT conduct elictricity!
