o rings for valve extenders

[bobsallyh]

Does anyone know what size of o ring is in a Wheel Master valve extender?

ssthrd, the o-ring fits in past the threads where the extender screws and seats on the metal valve stem on the wheel. Never had a problem with balance in 17 years on our dully.

In order to pull the ring out, it usually destroys the ring and can't really size it.

You might try an auto parts store. They should have a pretty good selection of o-rings. A fleet supply store may also be helpful.

The video is from eTrailer. Doesn't look like there is an O ring.

Curious to know if they upset the wheel balance to a noticeable level.
