Would this work in spark plug boots?

[The Artillerist]

I’m the OP. Instead of trying my luck with Syl-Glyde as a dielectric, I just order a proper one from Amazon with an overnight delivery between 4-8 am. Had it delivered before I woke up. No need to toss and turn whether I used an appropriate stuff

If it interfered with conduction then there was a problem with your terminal clamp. It wasn't making metal-to-metal contact, if the grease kept it apart then it was far too weak.

Beyond that, Dow Corning 111 is not "self leveling". It's a heavy grease that is designed to not sag. RTVs are self leveling when you wish for them to sink into a joint before curing.

Connector grease does not interfere with conductivity. Our test tutorials demonstrate the conductive and insulating properties of NyoGel® 760G.

You must use different Dow 111. Put a big dab on something and come back in a week and see what it does.

I don't understand why people can't figure out what dielectric means.

I know I took off the battery clamps and cleaned them off using nothing and the problem was solved. It takes awhile for that grease to respond to gravity but it never stops. It took a while for the battery to start showing signs of poor conductivity.

Yes silicones always migrate. That’s a hecka different than being a self leveling compound.

And I don’t understand why people can’t understand metal-to-metal conduction, and how air is a dielectric. Another mystery.

That’s what you want.

Air is easier for a weak, crappy connection to push out of the way, compared to a thick grease.

I wonder why the dielectric grease shown above says to “Use on bulbs, lamps & connectors”? Where are you supposed to apply it, on the glass envelope?

That would be a very weak connection.

That would be a very weak connection.

Easily remedied by the proper application of torque.

Another good place for a dielectric grease is in a multi-pin connector as it helps to eliminate fretting as well as exclude moisture.

I only apply dielectric grease where ceramic meets metal in the middle of the plug. There is normally a brown ring on ceramic on used plugs in that area.

Don’t laugh. I use MB dielectric grease on my MB boots.

A complete set of coils and plugs for one of my V-12 cars is about $3,000.

So, what’s another $10 to be certain I’ve got the right grease?

Mercedes says 1 gram of grease for each plug, by the way, which is quite a bit.

Nice thing about the one you ordered OP is that you can use it for just about everything.

Between that and that tube of syl glyde, you are set for life. Unless you ever have to pack a bearing or something.

It's a corrosion preventer and electrical insulator, it is a mechanical connection that passes current. If it's loose or there is a void then the dielectric does it's job. Or how about a pin that makes an intermittent connection (my taillight) grease would make it more than likely non working. Go ahead and fill it with grease. I prefer WD4 on connectors. A battery post has high current demands. There are proper corrosion preventers for battery post if you have a leaker. Live and learn.

I've been using it for 20+ years, no issues here.
Had no idea it wasn't silicone grease, I've used it on plumbing parts in the house too.

That makes no sense at all.

I prefer products made for the job and always use dielectric grease for spark plug wires/coil boots.

I suppose, if you serviced the sunroof on your cars, it was non less than an emerald-priced gleitpaste?

 

[mrbreezeet1]

Would this work on spark plug boots as a dielectric grease? Thanks

I say it would.

 

[mrbreezeet1]

“Probably” is not precise enough

Use it and don't worry about it!

 

[mrbreezeet1]

You don't need dielectric grease for it's dielectric qualities here. You need something to keep the rubber from fusing to the porcelain plug. Any silicon base grease will work.
