Default TPMS Nut....one time use?!

I took a set of OEM black rims I purchased from another member on this forum to my local dealer to day to get mounted. The service guy called me up a few hours ago and told me the Tech came back and said the aluminum nut that holds the TPMS sensor onto the rim is a one time use only nut. Apparently, to his surprise, they don't stock the TPMS repair kits which include this nut and the part is back ordered. He called around to some local tire shops, other dealers, and NAPA Auto parts and no one has them. I obviously don't want to buy a new TPMS kit.

He said with my permission, they can reuse them, but they needed to make me aware (I assume they are differing liability). I assume some lock tight on the threads would be good and that I should be OK reusing this nut?

Thoughts?

That is a crock, I use them over many times.

It's only a nut and a rubber washer, good for ever unless it is broken or damaged, which you would really have a hard time doing under normal use.

It would be years before they were unusable especially for the way corvettes are used.

No lock tight. Just reuse them. It just amazes me how uniformed and simply wrong some "techs" are about things that they are suppose to know about.

Interesting for those that change tire caps:

Before the tire is removed from the wheel note the following items to avoid tire pressure sensor damage upon tire dismounting.

◦Place the cap and the valve on a dry clean surface after removal, the cap is aluminum and the valve is nickel plated to prevent corrosion and are not to be substituted with a cap or valve made of any other material

My valve stem caps are gray plastic.

15122620 is the part number for the OEM correct caps, I went by dealer and picked up a set from the PDI department as they change all theirs to nitrogen caps. I will let them know in the future to leave the OEM ones with the car, believe it or not, they list for 5.49 each....

As long as you use plastic or aluminum caps, without brass inserts, it doesn't really matter whether they're OEM or not. You just want to make sure you never, ever, put caps with brass threads on your aluminum valves. They can literally weld themselves together through galvanic corrosion.

This is extremely good advice that 99% of people don't know (and obviously, it doesn't come up a lot in practical non-engineering applications) - bimetallic reactions are a PITA!
