Shower renovation - trying to install the Delta wall elbow (Model #50570) for a handheld shower wand. The male connection was supposed to be 1/16" to 3/16" past finished wall. It's not. It's barely sub flush with wall. I can't catch any threads when I try to screw on elbow with the black plastic gasket. I can screw the elbow on without the black plastic gasket. Does a short 1/2" MIP x 1/2"FIP bushing or adapter exist? Should I just install the elbow without the black plastic gasket? If I do that, should I put a bead of clear silicone around the elbow where it meets tile? Is there an issue with any options that I've listed? Any other suggestions? Pictures attached.
