Third in our rankings is this copper anti seize lubricant, also from Permatex. Much like our number 1, this one too has several features that make it one of the best options you can get your hands on.
Its main constituent is copper, and its functions include stopping corrosion and galling, especially when the parts build up a lot of heat. That provides electrical conductivity to the area where it is applied and is additionally modified with chemical agents that help prevent rusting.
Any good anti seize must also have a wide temperature range. This one has a range of -30F all the way to 1800F. Examples of parts where it can be applied include spark plugs, thermostat bolts, oxygen sensors, knock sensors, fuel filter parts, aluminum exhaust manifold bolts, and many others.
Compared to a lot of products, this can last for a longer period of time, usually in the range of years. It also comes with its own brush that makes application easier. One thing to keep in mind is that it is a petroleum-based product, so might not be suitable for some surfaces.
The temperature resistance also means that it can sometimes be used for purposes that were not originally intended. For example, if you need to lubricate parts of your wooden stove, then this can be the thing for you.
Fourth on the list is yet another lubricant from Permatex. Similar to the previous entry, this one also comprises of a refined combination of aluminium, copper, and graphite.
Once more, other kinds of surfaces, ranging from steel to non-metallic ones such as silicon, can be treated using this lubricant. The mixture is a good conductor and is suitable for parts that require this particular characteristic from any anti seize is used on them.
The product offers similar protection against corrosion, galling, salt, and moisture. Maritime use is one of its main applications. The material is not sticky and hence is easy to use and remove if need be. Something that also makes it safer to handle.
The temperature range is once more -60F to 1600F. It offers a similar function of hardening and hence not evaporating at high temperatures.
Again, the composition is a grease-based one, which is ideal for slow-moving vehicle parts. Lastly it is also very useful for the disassembly of parts. Examples of use are also identical to the previous product on this list; spark plugs, cylinder head bolts, etc.
Next up is this copper lubricant from Tribology/Tech-Lube. As the name implies, it comprises of a copper and graphite mix. Versatility is key when it comes to picking the best anti seize. This particular blend offers just that. It is micro-fine and suitable for all kinds of metals.
As with other anti seize products, it protects against rust and corrosion. Beyond that, however, there are some additional utilities on offer that make it a worthy inclusion on our list.
This is a silicon-based lube compared to the petroleum-based lubes that are otherwise available and used. It has highly desirable plating properties that help with getting rid of welding on the metallic surfaces of machine parts.
The lubricant is designed to minimize friction, and its action is extended over a long period of time and is very useful for assembling and disassembling parts. Finally, it comes with its own brush that can be used by the consumer for applying the anti seize.
