the O rings are about 3/8" and need to be stretched to about 3/4". They are so thin it is next to impossible to get them on without breaking them. I had 2 sets of 5 and that is what i needed, out of the 10 3 broke, had to use 2 of the old ones and one sensor has none. Seems like something like that, needing to stretch that much they should package a couple extra in the kit.
