Unfortunately these O-rings are too big for the groove and slightly smaller than the original. The original is thicker and fits perfectly in the groove. Does anyone know which actually fits which is the OME O-ring? After further research I found out that there are two different types of caps: the newer one, the o-ring fits right on top, the old one fits on the outside edges so it's taller and thinner so you need part number RKE0013HL-B.
