Recommended Tire Pressure Monitor System for Rubber Valve Stem with Brass Threads

Question:

I noticed there is a flow through version and a cap version. I checked on TST’s website to see the differences and they say the flow through can only be used on metal valve stems. So does that mean not to use the flow through version on the standard valve stem with the brass threads?

The TST TPMS for RVs - Color Display - Signal Booster - 4 Flow Through Tire Sensors # TST-507-FT-4-C as our product page states is brass construction designed for use on steel, chrome, or nickel valve stems. These flow through sensors are larger and require that metal stem for support like # AM20906.

The TST TPMS for RVs - Color Display - Signal Booster - 4 Tire Sensors # TST-507-RV-4-C on the other hand is brass construction designed for use on rubber, steel, chrome, or nickel valve stems like # AM20907 (made of chrome-plated brass).

If by standard valve stems you mean rubber with the brass threads, then the flow through sensors are not recommended and the cap sensors are a great option for you.
