Someone not long ago in a Thread said the #9 O-Ring at Home Depot was the ring that we needed for the Sensor. I just picked one up for .47 and the only specs that it gives is: 5/8 X 7/16 X 3/32. Does anyone have specs for the GM O-Ring to compare this with?

 

i don't know the specs.
i do know if it was me i would pay the extra bucks and get the o-rings from a GM parts dealer and that way you know it's the right specs.
just my .02.

 

I just recently transferred my sensors to my new powder coated rims, yes the #9 o-ring from Home Depot is the correct one. I moved the sensors over myself at the tire shop and they are a perfect fit. Dan

 

Hildy,

Chevrolet recently issued TSB #03-03-10-004 that states the grommet is replaceable with Chevrolet part #25715243. It does not give the specs. I would buy the correct Chevrolet part to ensure that you receive a grommet that is correct/fits. Good luck.
