TST 507 parts are expensive.

Big shout out to "Delphi".
Just bought the Danco #30 model #96744 "O" rings and they are a perfect fit for the TST 507.
The last time I changed batteries was just before leaving on a trip & no time to call TST so I used a small dab of goop glue. Just finished digging out all the goop & the Danco 30 fit perfect.
$2.49 at Lowes for a 10 pack, can't beat it.
Thanks Delphi.....

I watch the TP monitor fairly closely. I didn't see any pressure drop. We got to our location for the evening, and saw that one tire was completely shredded. I went back to the truck to check the monitor, and it still showed the tire had normal pressure (with no tire there at all).

My question is why after such poor support would you buy a second system.
If your truck had a engine failure when under warranty and they did not fix the engine would you then go buy a new truck of the same manufacture if it had the best reputation on a forum such as this one?

Possibly. Every company has a defective part or two sneak through. I usually buy items like this based on word of mouth as much as any other factor. If most are having good success with this product, chances are I will too next time around.

I've had outstanding customer service from TST. I called when I needed a couple screws for the anti-theft caps and they sent me a package of screws, extra caps, o rings for the valve stem connection and o rings for the battery cap--- all free of charge. I have enough to last a long time

I need to figure out what I'm doing wrong. I called TST a couple of years ago for o-rings, and was quoted a price and an equal price for shipping. I ended up ordering 2 sets of o-rings since the shipping charge was the same. Last trip (last month), I had a sensor fail. It reported no change in the tire pressure even after the tire had totally ripped itself apart. I no longer trusted the system I had. TST was no help, even though the sensor was less than a year old. I did end up buying a hew TST system as it seems to have the best reputation on the forums, and I wanted the color monitor and repeater. I got it from Great RV Products rather than TST directly.
How do some of you get this stuff sent free?

I suggest you call Mike Benson at 210-420-0132-- He's the sales manager at TST and has been very helpful.

Thanks for the tip on the HD o rings. I've broken new ones from TST just trying to stretch them on. I never understood why they made them so tight.

Now I know where I'm going tomorrow morning. Thanks for the tip.
