Can PVC schedule 40 be used for a threaded tub spout nipple? I have been struggling to stop leaks coming from a copper nipple that I made from sweat fittings and 1/2" copper pipe. I believe I have traced the leaks to damaged (prior to my purchasing) male threads on the copper male adapter.

I sorted through most of a box of threaded male adapters in Home Depot, and they were all damaged. My theory is when they were shipped from China, they were at the bottom of a 10 foot high stack of boxes. The weight and vibration during shipping garbaged up the threads. I was looking for a cast bronze x sweat threaded male adapter, because I thought this would give me a better chance at having higher quality threads.

I want to use PVC threaded male adapters, solvent welded to 1/2" PVC pipe. Is this OK? I want to to this route because I know the threads will be good, and I am more confident I can get the nipple length exactly right to ensure the proper fit. I am less confident with this process with copper.

Thanks for any replies.

I'd get a brass fitting. I know around here, HD has a variety of brass fittings in individual plastic hang bags on their display. I'd want metal to the spout.

Not a good idea. The plastic could snap if you hit or grab the spout. Use the proper length brass nipple, or two short nipples and a coupling if you have a problem with the exact length, and you don't have to worry about leaks.

Thanks guys. I'll use a couple brass nipples and a coupling.

It worked! Thanks guys. I used a brass 4" + 2 1/2" + coupling to create a good stub out.
