TST 507 Non Flow Thru Tire Sensor - 2 Pack

The TST 507 RV that these work with is a real lifesaver. I had to buy two extra sensors as they were on my boat trailer and leaked. They have O rings and were installed properly, but still leaked. Keep them out of the water and they work perfectly. Just take them off when backing into the water and replace them when you pull out.

I use these on my RV and flat tow car. They work better than the flow through type - which don’t last as long. Several of these have lasted 50,000 miles with minimal care and simply replacing the battery. I found the flow through version gave bad readings near their end of life and did not allow flow through air. Great product that works and lasts.

These are to add on a trailer I pull behind the motor home. TST system is top notch and very reliable. On top of that, their customer service is, repeatedly, excellentas good as it gets

This company is a very respectable company that offers a great product. I have the system installed on my truck and fifth wheel and HIGHLY HIGHLY recommend this for everyone that is looking for a tpms system. I contacted them with a number of questions and they were very responsive and courteous.

What I like the most is the ease of installing and removing the sensors using the tool that comes with the non flow sensors. I also use the flow through on my motor home, you can use either one or both types on one vehicle.

These are slightly different than the ones I got in my original kit. These require a wrench to tighten as the brass part is a swivel separate from the black sensor. Still read and program the same but in tight spots hard to attach.

Works great with the TST monitor....

The are working good!
