Left or Right handed thread for steam radiator

I am attempting to replace an existing radiator for my single pipe steam system for another one. However on the replacement radiator (used one) for lack of a better term, the knuckle that screws into the radiator will not budge (please see picture as "this"). I have a monster pipe wrench but this does not seem to want to budge. I have tried spraying it with "blaster" PB Penetrator and it just won't do anything. I have tried spraying it and letting it sit for hours and spraying it again. I just want to be sure that I am attempting to loosen it the proper direction. Does this have a left or right hand thread? Any suggestions as to how I may be able to loosen this.

Thanks

Use a spud wrench to get the coupling off.. The hub you will need to cut it out...

There is a vid on that somewhere.. Let me see if I can find it...

I found this one.. This guy had the right idea but he ruined the rad by cutting too deep into the threads.... That will leak for sure IMO...

There is another vid.. Im still looking...
