ABSTRACT:
A hub connection assembly 20 includes a hub 22 having a spout 28 extending therefrom. The assembly 20 further includes a trim nut 30 which is assembled with the hub 22 and also includes a split snap ring 32 which retains the hub with the trim nut. A lower section 26 of the hub 22 is formed with a outward facing annular recess 36 which receives a circular wall 74 of the ring 32. The ring 32 is also formed with an outward extending circular rib 68 which is located in an annular groove 48 formed in an inner circular wall of the trim nut 30. The wall 74 and the rib 68 of the ring 32 extend in a direction between the hub 22 and the trim nut 30 to maintain separation between the hub and the nut.
