Hello I am trying to install the Wayne battery backup sump pump.
The pump has 1.5 inch NPT discharge which is made of metal (female side)
I bought this PVC male adapter to screw into the metal female discharge.

I am unable to hand tight the adapter more than a single thread or two. It just becomes extremely tight and I am afraid I will strip the thread if I apply more force. Is this normal?
What am I missing? Should I buy a different brand adapter? Did I buy the wrong adapter? Is it supposed to screw only a couple of threads before I use a wrench?
I have tried using plumbers tape on the male adapter and it did not help.
