The problem usually arises in practice because the wrong inner valves and valve caps are used. As mentioned earlier, it is very easy to use the wrong parts.

In the automotive and certainly in the tire world, copper inner valves have been used for years in combination with copper valve housings (e.g. theTR413). These have been on the market for so long that everyone who does have stock in the tire mounting device.

It is absolutely not allowed to use these copper inner valves with a TPMS valve with an aluminum valve body! ALWAYS use the nickel plated inner valves.

It is better to immediately throw away the stock of these old copper valves and replace the nickel-plated version. These can be used without problems in both types of inner valves.

Fitting the wrong type of inner valve is the most common mistake that is made. But attention should also be paid to the valve cap!

It should sit over the top of the valve body and have an internal rubber ring that seals it from moisture and dirt ingress.

By following these, actually very simple, maintenance instructions, galvanic corrosion will be prevented. Of course there is even more to it if the entire valve part is to be properly maintained according to factory instructions, but the fact remains that by following these 2 simple recommendations, the majority of the corrosion problems will hardly occur.
