Anti-seize applications
The main reason I started using anti-seize was because I used stainless steel hardware on the new torque tube boots. A few of the bolts/nuts stuck together and broke before they would come free. This was my first experience with galling. I was told by Matt at Belmetric that I had to use anti-seize when using stainless on stainless nuts/bolts. So, I personally, use copper Permatex on all stainless steel threads.
Searching on the internet you get a lot of “information” about which anti-seize lubricants to use on which parts. You get a lot of what not to do as well, which can be scary if you are afraid of destroying your Unimog. A lot of people say “do not use copper anti-seize on stainless”.
Recently, while searching what to use on my fuel tank fitting threads, I went directly to Permatex and read the technical sheets for all three of their anti-seize products. This is a summation and easy to see comparison of those three products and tells you everything you need to know. Enough of the internet “experts”!
| Nickel | Copper | Original (Aluminium, copper and graphite) | |
| Buy: | Amazon | Amazon | Amazon |
| Tech Sheet: | Tech sheet | Tech sheet | Tech sheet |
| Protection: | Heat, freezing, seizure or galling | Heat, freezing, seizure or galling | Galling, seizing and corrosion |
| Temperature range: | -65F to 2400F (-54C to 1316C) | -30F to 1800F (-1C to 982C) | -60F to 1,600F (-51C to 870C) |
| Use with these materials: | Stainless steel, titanium and nickel alloys | Stainless steel or similar alloys | Does not state |
| Why use: | When Copper contamination must be avoided and under conditions of extreme pressure and temperature. So, basically when Copper anti-seize shouldn’t be used. | Where good electrical conductivity is needed. When Military Specification Mil-A-907E is needed. | Reduce corrosion and seizing due to weathering or chemicals Permits easy disassembly of parts exposed to heat or corrosive environments |
| Do not use: | Not for use on wheel lug nut or stud applications. Not recommended for use in pure oxygen and/or oxygen rich systems and should not be selected as a lubricant for chlorine or other strong oxidizing materials. | Not for use on wheel lug nut or stud applications.
