The spot where you have the arrow is 1/2"-14 NPT. My kegger doesn't have the one you circled. WK had a good idea for comparing it to the heater outlet. That is 3/8"-18 NPT.

Thanks for the additional ideas folks. I thought those ports may have been a metric thread, but wasn't sure. I'll test fit some 1/2"x14 NPT and 3/8"x18 NPT plugs and see if they work.
