    Looks like a left-right nipple and a cap might be the most commonly available solution.

    Depends on how many you order.

    Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

    Is the radiator itself left hand thread or is there a bushing in the radiator that is right-left that was used to couple 2 radiators together or make up a fitting with a return without a union or something that could be removed and replaced with a larger right hand thread plug?

    I wonder if there are shops in china with CNC machines that you can send a file to for fabrication cheaply the same way you can send printed circuit boards.

    I use a cap and 4” nipple or i cut the nipple just past the left hand threads and weld a disc onto the cut end.
