What material nipple should be used?
What type of metal should be used for the nipple (brass, black steel, etc.) where's a good place to get it from also?
Dear Andrew T,
Thank you for your question. To install the Delta Square Wall Elbow for Hand Shower 50570-SS, you would need 1/2" copper or galvanized pipe. The nipple should extend past the finished wall no more than 3/16" (4.8 mm) and no less than 1/16" (1.6 mm). You would want to check with your local plumbing dealer for these types of pipes.

Is there any reason this cannot be installed without the gasket?
The wall tile it will be installed on is textured and wouldn't provide a water tight seal anyways. So, is there any harm in installing without the gasket and adding a bead of silicone? I need to do this because the required nipple length is in between 1/2" sizes and I need the extra 1/8" of threading to get a good seal.
Thank you for your question. We recommend using the gasket as it helps to protect the wall during installation as well. You may use a bead of silicone to help provide a water tight seal.

1/2" pipe nipple length
My 1/2" pipe nipple extends 1/4" from the finished surface.
At this point, I'm not able to replace the pipe nipple. Is there any kind of extension or additional gasket that I can install.
Hi Dan, Thank you for your question. Unfortunately we do not offer an extension or gasket to solve your issue of the pipe nipple extending too far from the wall. You may be able to use caulk to make up the 1/16" difference in depth if you cannot change the nipple.
