How to Prevent Leaks at Threaded Pipe Connections

[@tigerboy60]

I have a 1 inch cold water supply line attaching to the well casing Male pvc to female metal I didnt tighten it quite enough and I have a small pinhole air leak where the threads meet the metal. I cant tighten it because everything else is glued. What can I do without taking everything apart?

Do you need tape for plastic pipes?
