Best sealant for threaded connections?

I have a 3/4" PVC pipe that ends in a slip-to-threaded adapter that I'm screwing into a brass sprinkler valve with female threaded ports on the bottom.

Generally with threaded connections I use "T Plus 2" brand pipe thread sealant paste (PTFE). After I applied it, tightened the connections and opened up the water supply, I see a single drop of water coming out of the threaded connection on the supply side of the valve about once every three seconds. The pipe was fully tightened down without what I'd say is over-torquing. The drip is definitely coming out of the threaded connection at the valve, not the slip joint between the PVC pipe and adapter.

So, is there a doping material that you think would work better?

I've never had really good luck with teflon tape, but if you want to say it's really the way to go, how many layers do you wrap? When I used to try using tape I was never able to get that right.

I don't know what are u talking about.

I also couldn't figure out a similar question for a long time. I was constantly looking for which materials I should use here and which ones here. But my friend told me that I need to contact specialists. But I didn't want to get anyone because there is a pandemic now. So I had to find the information myself. And you won't believe it. I've read so many different articles about it. Now I know a lot more! However, I spent only a couple of days on this one. Therefore, try to search for information on the Internet yourself. Now there are a lot of books and articles that will help you. The only thing you need is to enter the query correctly.
