Radiator Help

I have hot water heat with radiators in every room. I have a
leak in the nipple that attaches the pressure relief valve. I took the valve off and half the nipple stayed in the radiator. I'm
hoping I can use an easy-out to get it out. If not, can I retap
the radiator ( It's cast iron)? Will something like liquid steel
work to plug it?

Broken nipple

Forget the easy out. You could crack the radiator. I've drilled out the broken part & re-tapped radiators several times. Drill a little at a time increasing bit size as you go. Take your time with the tap. The last two things you want to happen are breaking off a cutting tool in the hole & cracking the radiator.
