pliers= bad idea, you will probably damage the threads. using a rubber jar opener to grab it works better, if you cannot get it still you can use pliers with something thick between it so it dosent mar it.
some times it comes out easy some times not.
i also found that some times you can go get the generic port adapters that are female threads that screw onto that piece there. i was able to use the piece from my rotator that works perfectly
