TPMS Questions - Brass vs. Aluminum

[StringFellow]

I finally installed the Borg Dually value stem extensions this morning after I had a flat in Yellowstone earlier this month due to my extensions.

Now that I have the valve stems installed I want to install a TPMS for both my RV and Jeep. I have some questions regarding which sensor to install (brass vs. aluminum).

On my RV I have the chrome Borg Dually valves stems. Based on the information I have read I need to install brass TPMS sensors. Correct?

Now for the Jeep Wrangler. It is a 2015 with integrated TPMS (I believe direct/banded). It has rubber valve stems and when I remove the caps it looks brass to me. Do I need aluminum TPMS sensors for the Jeep? These add-on sensors would be used to monitor the tires from the RV.

Brass for both - aluminum has a tendency to corrode

Just to be safe, it is always smart to apply non-seize grease when installing the sensors. Just a dab will do you! I would also wonder if the rubber valve stems on the toad can support the sensor centrifugal force. I had my rubber stems replaced with metal ones.

Absolutely use a protectant oil, silicone lube or anti-seize on those aluminum valve stems. I mistakenly just screwed mine on and after 6 months the fronts were practically welded on. I just managed to get them off without messing up the toad's own factory TP sensor stems; one sensor survived, the other didn't.

I put brass sensors on aluminum valve extensions and they corroded together trash 2 sensors and extentions.

Brass to brass. You told us the jeep has brass thread, so use brass there. You said you have chrome dually extenders. Those are also brass. So use brass there too.

Agree with the others, Brass to Brass. You could probably use aluminum, but why take a chance?
