Is a compression fitting available in the size of that thread on top? If so, can you run a copper tube inside the hole through the top, clamp it in place with the compression fitting and do what you have to do on either end of the pipe? If so you could also use that to raise or lower the top of the sparge arm which might be handy if you have to drop it down after closing the lid.
