Video Transcript for Review of TST Replacement SE2 Cap Sensor - TST47FR

Hi everyone. Steven here with etrailer.com. Let's take a look at our replacement SE-2 cap sensor for the TST 507 Series TPMS System. So folks, this replaces one, quantity one, of your SE-2 cap sensor for that TST 507 Series TPMS, or tire pressure monitoring system. It works with all those TST 507 Series systems, and both metal and rubber valve stems. If you don't already know, you simply screw this in place of the factory valve stem cap, and you're good to go with the rest of the sensor system.

Well, that's gonna wrap it up folks, for our quick look today. I'm Steven. Thanks for watching.

I received tech support from TST, looked for best price for the product and chose etrailer.com. The item, TPMS sensor for our spare tire on our RV, came in on time and it is just right for my application. The installation will be easier than I expected.

We had a wheel fall off our Montana on one of our road trips. So, we purchased the TST sensor. Since the we upgraded to a Brinkley that has a TST TPMS on 4 wheels. I purchased a stem mounted sensor. The TST team, again helped get every wheel synced and on our first road trip provided excellent help with an issue we experienced. I dont think anyone with an RV should go without a TPMS and I appreciate TST.

Fast shipping.

Works great. I did have to contact support to get one of my sensors to show up on the display again. But once I tried the Go and + they recommended, this sensor shows up and all is good again. I recommend getting additional ORings. I wish they sold them in packages with 2 extra. They break easily when replacing them.

@Susan Glad to hear the sensor is holding up as it should Susan =) What kind of trailer, or application are you using the sensors on?
by:
These were to replace older sensor and monitor. Took some doing but was able to get all the old sensors to work with the new monitor. Found out the old cap sensor was good but the tire valve was bad. Tire leaked air when driven with the cap sensor. Once tire valve was replaced, it worked as advertised. Thank you for helping me with this purchase.

My order was filled and shipped quick.

Monitor was received on the date and day as said via USPS. I have not put said CAP SENSOR Monitor for TST 507 series on the tire at this point, though I did check see if it it would actually fit and it does. Placement of said sensor on tire for travel will take place in the next few days but it does appear to be what was definitely needed as a replacement. Thank You Very Much.

  • Does the TST Cap Sensor Work with Metal or Rubber Valve Stems?
    Hi Jerry, The TST website shows that their cap style sensors like part # TST47FR will work with either rubber or metal valve stems, so the rubber valve stems you have currently will work just fine. If you're still wanting to switch to metal valve stems for your Taskmaster Viking 16 Aluminum rims part # TA75FR you can use the Americana Metal, Bolt-In Valve Stem part # AM20906. It's ideal if you're needing a higher psi, as rubber valve stems are rated for 80 psi while metal valve stems...

  • Solution for Adding Additional Sensors to TST TPMS System
    Hey Adam, we have the replacement SE2 cap sensor part # TST47FR that will work with what you have and is pretty small so it wouldn't stick out far enough to cause you any issues or problems with curbs. These are sold individually too so you wouldn't have to order more than you'd need. How do you like the TST system so far?

  • Replacement Sensors For The TST TPMS System TST-507-RV-6-C
    Hi Christian! We have replacement sensors in one, two, and four packs, which I have linked below. I would grab a two pack and a four pack as it will be the most economical way to go. Brass Tire Sensors for TST TPMS - Qty 1 # TST47FR Brass Tire Sensors for TST TPMS - Qty 2 # TST-507-RV-S2 Brass Tire Sensors for TST TPMS - Qty 4 # TST-507-RV-S4 Are wanting the new sensors for a new vehicle/trailer? Or something else?

  • What TPMS to Use for Monitoring Single Axle Trailer and Spare Tire
    It's great to hear from you again, Kenneth! Yes, what you're wanting is the TST TPMS for Trailers and Cars - 2 Cap Sensors # TST63FR, and then you can add one more cap sensor with the part # TST47FR. There aren't any TPMS that come with 3 sensors because most people just put the sensors on the active tires. I like your idea of putting one on the spare though! Let me know if you have any other questions!

  • Availability of TST TPMS for Trailers and Cars With 10 Sensors
    Hi Rick; the TST TPMS for Trailers and Cars # TST35FR with 8 sensors is the largest one we have that comes together. Since you want 10 sensors all you need to do is pick up two more Replacement SE2 Cap Sensors # TST47FR. The system itself can handle 10 so adding the additional sensors won't be a problem. Are you adding these to a motorhome?
