Permatex 22058 Dielectric Tune-Up Grease, 3 oz. Tube

Works as advertised.

I didnt wanna spend a ton of my hard earned bread on some overpriced Krytox just to lube up my stabs. So I got this instead. Honestly the quality is good, I wouldnt say that it performs better, but for the price its hard to say no.

Was having problems with my cctv system and this stuff did the trick. It seems that no mater how much tape or shrink tube you put on the connections outside, you will still find water in them over time. With this stuff I was able to clean the BNC connectors and apply a small amount before reconnecting to keep out any moisture. Ever since I started using the dielectric I have had no issues with signal quality or power problems due to corrosion. Well be buying more when I run out and I would highly recommend using this on any outdoor connection.

This is 3 oz of silicone grease (dielectric grease). I paid around $8 and the ad showed a package with Japanese writing on it. Who cares? The same product with English labeling in the ad was twice the price. Ended up receiving the latter anyways. For comparison, a half-ounce tube of Danco Grease is $4. Good stuff and a good applicator tip, but pricey. I use this for protecting electrical connections on automotive wiring and soldered joints before wrapping them in heat shrink tubing. I also use this for lubricating my o-rings on scuba gear and underwater flashlights. Not a bad idea for your home flashlights if you do any camping and risk exposure to rain, too. Silicone grease is also sold for plumbing applications (faucet grease), but that application only sees very occasional use. This is not high-temp lube and will burn if you get it super hot. So dont be applying it to your sparkplug threads--modern plugs dont even require lube or anti-seize anymore. But its also great to apply to your cars battery terminal connectors, inside and out, to prevent corrosion thats accelerated by atmospheric humidity. Yes, it is likely that I will never need to buy another tube of silicone/dielectric grease again. Others have complained that the caps are prone to breakage, thus rendering these tubes useless without a cap. Even if the cap quality is defective, I see no reason why a replacement cap cant be easily located (even from a tube of toothpaste, perhaps!). Its not like theyre using proprietary threading on the tube neck... So cap breakage is not really a concern to me. That said, for the Average Joe, this tube could last a lifetime. Your offspring will be delighted to receive a half tube of this grease when you pass. Another complaint is that its difficult to apply with the toothpaste-tube shaped nozzle instead of a pointed applicator nozzle. Big deal. For electrical connections you can use a toothpick or your fingers. For o-rings I use my fingers. For plumbing applications youre probably going to slather it on anyways and clean up the excess. Would a pointed tube be better? Sure. Is it essential? No. Could you probably locate one if you really wanted it? Probably. This stuff is translucent in bulk, but is essentially transparent at the thicknesses typically used. Good stuff. Fraction of the price of my other favorite little tubes of Danco, and will last a looong time if youre not a plumber or are prone to giving up on life if a little plastic cap breaks!

Great product and a great seller I will purchase from them in the future!!

As would be expected from Amazon, this item is offered at a good price, and it is a larger tube then is usually found in general retail. In general, dielectric grease is used, and indeed required, to prevent corrosion from occurring in electrical connectors (such as plugs and sockets) and connections (such as battery terminals). It does this well because the thorough application of the grease excludes oxygen, the presence of which is generally essential to the forming of corrosion, or oxidation. Again, it is useful that it is dielectric (meaning totally non-conductive) as this precludes any possibility of an inadvertent electrical contact, such as a short. In fact, a shade-tree mechanic can actually use Vaseline for this purpose, and this is certainly better than nothing. There are in fact, of course, conducting electrical greases, which facilitate conductivity in their application if used carefully, and I have written of such in another review. I dont believe that it is quite accurate - or informative - to call it tune-up grease, as it is certainly appropriate thus but definitely not only so. For instance, it should be used at both ends of the spark-plug wires, for instance, but really nearly any electrical connection benefits thusly.

It is what you expect.

Great product for sealing up wires and coating backs of ignition modules and on spark plug boots. Seals out moisture and protects components from overheating and sticking.

Works very well on threads. Easy to apply.

This product was recommended by Modlite for their flashlights. It makes sense to use it on the tail and head caps to maintain a good connection. It also minimizes the chance of galling between the units. I now use this on all my high-end flashlight units.
