That fitting does not look right. There's too much sticking out of the pipe-thread end.
The way those fit in the case, if you are careful to not tap too far down, I think it will work fine with a new correct fitting and no sealer at all. At worst, you might have to spot face the entrance to make room for the hex, and the wrench/socket.
