On valve stem # AM20906 the metal washer has an outer diameter of 0.74 inches and inner diameter of 0.41 inches. The large rubber grommet has an outer diameter of 0.75 inches and inner diameter of 0.38 inches and is 0.3 inches tall. The small grommet has an outer diameter of 0.75 inches and inner diameter of 0.4 inches and is 0.25 inches tall. The stem has an overall length of 1.56 inches. I have included a picture showing these measurements for you.

It is the rubber grommets that dictate the size holes that valve stem # AM20906 will fit. It comes with 2. One allows it to fit holes that are 0.453 inches in diameter and the other allows it to fit holes that are 0.625 inches in diameter.
