## Description

Permatex Dielectric Tune-Up Grease protects electrical connections and wiring from salt, dirt and corrosion. Required for modern high energy ignition systems, dialectric grease extends the life of bulb sockets and prevents voltage leaks around any electrical connection. Also prevents spark plugs from fusing to boots. Suggested applications: marine and automotive electrical connections, spark plug boots, trailer hitches, and battery terminals.

Review: Cheap, effective, and worth having on hand - I've been using this dielectric grease on spark plug boots, battery terminals, and trailer connectors for a while now, and it does exactly what it's supposed to. A little goes a long way—it spreads smoothly, stays in place, and creates a solid barrier against moisture and corrosion. It's made a noticeable difference in keeping connections clean and makes removing spark plug boots way easier down the road. I've also used it on light bulb threads to keep them from seizing. A single tube lasts forever, so for the price, it's hard to beat. If you do any kind of electrical work on cars or around the house, this is one of those cheap items that's genuinely worth having.
Review: Auto shop use, decent little tube - This stuff rides in the drawer under my shop counter with the spare keys and receipt paper. I bought it to deal with flaky connections on our front doorbell camera and the POS terminal. I pulled the plugs, wiped them down, dabbed a tiny bit of grease, then snapped everything back. No more random disconnects right when a line of customers shows up. I also used it on my truck’s spark plug boots last tune-up in the parking lot during a slow afternoon. Boots slipped on easier and came off clean later. One tube is going to last my little business and my vehicles for a long time, which makes me glad I grabbed it.

## Questions & Answers

**Q: Can it be used for mechanical switchs on keyboard**
A: On a mechanical keyboard, you would only want to use this on the stabilizers where the metal bars come into contact with the housing. As for the switches themselves, you would want to use a much thinner lubricant. Suggestions are below:
Linear - Krytox 205g0 is a thicker lubricant that can help linears feel super smooth.
Tactile - Tribosys 3203 is thinner and provides good performance. Avoid lubing the legs, as these are responsible for the "bump" in tactile switches.
Clicky - Although you can lube clicky switches, nearly everyone recommends not doing so, as there is a high chance of losing some of what makes a clicky switch appealing to those who enjoy it.

**Q: How many uses do you get out if this tube?**
A: Depends on how it is used and for what. It will obviously last longer when used on small jobs vs. 
big jobs.

**Q: Is it a good product to use on ordinary home inside or flood lightbulbs? thanks**
A: Absolutely, it will keep bulbs from freezing into the sockets, it keeps oxidation out of any connections.

**Q: Can this be used with rubber O rings on flashlight?**
A: I am sure that it would not harm the o ring if you use it.

This stuff rides in the drawer under my shop counter with the spare keys and receipt paper. I bought it to deal with flaky connections on our front doorbell camera and the POS terminal.

### ⭐⭐⭐⭐⭐ Handy little tube for car jobs
*by S***T on June 7, 2026*

Wiped this on my car’s battery terminals after a 12 hour night shift because the engine had been cranking slow and the posts kept getting crusty. The tube is small but you only use a dab each time so it’ll last a while. Texture is thick, kind of like clear jelly, and it stays put when i slide the connectors back on. I’ve also used it on my spark plug boots and the headlight sockets in my old Civic. No more weird flickering on the way to work at 6am, which made me really glad i bought it. Tube cap seals tight, no mess in tge toolbox.
