im tryin to figure out if i can use it on my spark plug wires, lithium grease that is

why? if your wanting to seal them buy a spray can of silicone and use it. if your wanting to seal the boots use the "grease" made for that.

ede's right, use the stuff designed for the job.

Lithium is an element, and it is used in soap form as a thickener for grease. It is also used to treat bi-polar conditions ("Chill out, you manic!).

Actually, I think the grease you want for electrical connections is Di-electric Grease, not Litium (which may be a componenent) of Di-electric Grease.

Litium Grease if very clingy and sticky. It is good for latches, hinges etc where it may be exposed to the elements and won't break down or attract crud.

Di-electric grease (also white) is specifically made to resist electrolysis and stops that corrosion like you see occasionally on battery terminals. It also conducts electricity. Look for di-electric grease, not lithium grease.

Actually, Glenn, dielectric means it does NOT conduct electricity. If it was a conductor, you wouldn't want to put it on your plug boots!

The Permatex tube I have says it contains silicone, but doesn't say anything about lithium.

Again, lithium can be used as a thickening agent (soap) in either petroleum or synthetic greases. I've never heard of it being used in silicone products, but I don't know everything...

i wasnt talking about sealing or cleaning. im making a custom set and i just wanted to know if that was ok to use for putting the boots on

Just for reference, lithium is a mineral. Use silicone dielectric grease on plug boots, weatherpack connectors, etc.

Silicone dielectric grease has a high resistance, but is an adequate electrical conductor when used to lubricate electrical connections due to its thin coating between the contacts, and is very good at keeping water and corrosion out. I use it in all of my electrical connections under the hood. All of the dielectric grease that I have used is clear, but I'm sure that it's possible that it's sold in white also.

I actually went to look at my tube to see what color (if it any it was), it is basically clear with a slight opaic tint.

Regardless, I fully agree with Jim and use it on ALL of my electrical connections, especially where there is any risk of exposure to moisture. I also put it on the inside of the boots and on the threads of the spark plugs. Makes it easier 30,000 miles later to remove them.

89CamaroRs, you want to use this stuff to slide the boots on, and that's it, right?

The Di-electric stuff works fine for this. Hot Rod used WD-40 in one of their articles to slide the boots onto the wires, but I'm not so sure about that. Grease/oil usually works its way into the insulation of spark plug wires, and causes "spark leak". Seems that WD-40 would be the same as grease/oil.

I've always used di-electric when building my MSD wires, use enough, and the boots slide on really easily.
