 thru tub wall spout
Author: g bruce (AR)

I have a 100-year-old cast iron bathtub that has the spout mounted thru the wall of the tub. The spout is chrome-plated brass. It is held in place with a cast brass bushing/washer thru which is a brass allthread nipple. There is an iron locknut threaded onto the nipple on the outside of the tub wall. I have managed to back off the locknut and remove the spout. I have cleaned all the treads, inspected them and they appear to be in good shape. My question is, should I replace the locknut with a brass one, or is there some sort of coating I should apply to the iron locknut and reuse it?

brass or stainless is always better.
if you can not locate a new nut with the correct threads then lather everything up with a silicone grease.
