I recently installed a new tub/shower surround and faucet where I had to make up a copper spout nipple to make things fit properly. The problem I'm having thought is that I have a small (~ 1/8") gap between the spout and the surround wall. Does anyone know if there are seals that a person can purchase to place between the wall and the spout? I was hoping that I could find something that would look a bit better than just a ring of caulk. Any help would be greatly appreciated. Thanks.
