Aluminum Valve Stems & Galvanic Corrosion

What is Galvanic Corrosion?

Galvanic corrosion, also known as bimetallic corrosion, is an electrochemical process whereby one metal corrodes in preference to another metal that it is in contact with through an electrolyte. Galvanic corrosion occurs when two dissimilar metals are immersed in a conductive solution and are electrically connected.

All towed motorized vehicles, such as cars, trucks and SUVs, will have either rubber (brass) or metal (aluminum) valve stems. If you have a rubber valve stem, you will need to use the included brass transmitters. If you have an aluminum valve stem, you will need to use aluminum transmitters. Older towed vehicles almost always have brass valve stems, unless an aftermarket aluminum valve stem was installed.

Vehicles such as RVs, motorhomes, 5th wheels, and trailers will all have either rubber, steel, chrome, or nickel-plated chrome valve stems, all of which work with the TireMinder brass transmitters.

All TireMinder kits come with brass transmitters. If you need aluminum transmitters, please reach out to us by phone Monday through Friday, 9 AM to 5 PM, at 772-463-6522 or email at info@minderresearch.com.
