Deciding Between Flow-Through and Cap Style TPMS Sensors for an RV  

Updated 06/03/2020 | Published 06/02/2020



Question:

Hello - looking at purchasing a TPMS for our 5th wheel trailer and after looking at reviews, some mention the difference between rubber and metal valve stems - our alloy wheels have a metal valve but there is a rubber seal where the stem meets the wheel rim. Some reviews have commented on problems with the cap style monitor on rubber stems. Which type of system would work best - the flow thru monitor or the cap style monitor - value your opinions- thanks.

Helpful Expert Reply:

If you have valve stems with a metal body like the Americana Metal, Bolt-In Valve Stem part # AM20906 then you will want to use flow-through sensors but if you have valve stems with a rubber body like the Americana Rubber, Snap-In Valve Stem part # AM20903 then you will want to use the cap style sensors. The TST TPMS for RVs part # TST-507-FT-4-C and part # TST-507-RV-4-C are my recommendations.
