TST o-rings: where to buy?

I got mine from TST. Just contact them.

The 510 system does not have user replaceable batteries. The 507 system does. TST will sent you new 'O' rings free for the asking

Trying to replace batteries in TST 510 tire monitors. I will get batteries from Walmart or Radio Shack, but where can I find replacement o-rings? I looked at TST website, but did not find o-rings in their on-line catalogue.

I have not replaced my batteries yet but TST sent extra o-rings when I bought my system. I believe they will mail them to you for free as suggested above. Another idea is to call and ask them the size of the o-ring for future reference so you could source them locally.

I find that Napa or the like orings work better and don't fuse themselves to the valve stem when you remove the sensors. TST will happily send you theirs at no charge, their customer service is awesome.

I called TST and they sent several for free. :) When I needed I was leaving for a trip so I went to a auto parts store and got a couple of "O" rings and used those and they are still on the sensors. I just kept the replacements from TST for spares. :)

They sent extra O rings when I ordered the system.

Very responsive, call or email.

Call the manufacture. I have heard of people getting them for free.
