I need to install a new tub spout at my mom's house so we can sell the

Unfortunately, the pipe is about 1/2 inch too short for the tub spout to
thread on.

I thought about using a slip-on style of tub spout, but the ones I have
seen are made for copper pipe which has a smaller OD than galvanized pipe..

Ideally I would just remove the existing pipe stub and thread in a longer
pipe nipple. Unfortunately I tried doing that and the piping in the wall
started to bend. So that's not an option. I don't have the time or money
for this to turn into a larger project, we just need to sell the house.

I can't think of an easy way to extend the galvanized pipe just one half of
an inch. Adding a coupler and a short nipple is still too long.

I thought about cutting back the pipe and rethreading the end so I could
install a coupling and correct length nipple. But I can't find a NPT die
locally and the few I've seen online are quite expensive for what I'm
doing.

Do you know of a chrome slip-on spout with diverter that will fit
galvanized pipe?

Or do you know of an easy way to extend galvanized pipe just 1/2 inch?

Thanks,

Anthony

Take a look at the links and see if it gives you an idea of what to do. If you have a vice you could trim the female part of the brass fitting. Your local hardware, plumbing supply or big box store may have the same items. ヽ(ヅ)ノ
