The tape should work. FYI, the tape is not a sealant though all it does is allow you to get a couple more turns out of it.
That's incorrect. Teflon tape is a thread sealant.
Actually, no. It is not a thread sealant.

The use of PTFE tape in tapered pipe threads performs a lubricating function, which more easily allows the threads to be screwed together, to the point of deformation, which is what creates the seal.

Wikipedia is nice, but not authoritative. There are a number of inaccuracies in the article you reference. Here are some industry links:

If you need more, I can provide them. In my personal experience of more than 28 years of plumbing, I have installed thousands of feet of threaded pipe, from 1/8" to 4", of black iron, galvanized, stainless steel, brass, and plastics. I have a pretty good idea of what is, and what is not, a sealant.
3/4 of those links are just marketing. LOL, if you take that seriously.
Whatever, think what you want.
I'm not questioning your 28 years of plumbing experience, I'm just reiterating what I've been told and seen first hand.
It's not rocket science. The tape acts as a lubricant and allows you to get more turns out of it.
I'm done here.
Yes, you're done, since you have nothing to back up your claims. And there's a lot more science to it than you think. I've also made gaskets out of PTFE tape, and reinforced failing gaskets when I couldn't get a new one. It's a good gasket material, due to its ductility and strength. PTFE also comes in cord for making gaskets.
Pipe thread sealing is accomplished by filling, or sealing, small, even microscopic voids in the threads. Field-cut threads often have visible defects, yet, when the correct sealant (often PTFE tape) is applied and the joint made up, they will give good, long-term, leak-free service. Lubrication is a side benefit of many of these sealants.
