You put the Gray O-Ring in the groove at the top of the stem and the black o-ring in the disc just below the stem top.. Note: There are times that the disc part is hard to get into the old diverter body so you have to trim the inside of the body a little with a razor knife to remove the edge that has worked it's way in with age..
