Removing a stubborn steam plug
I’ve got an extra steam radiator that I’d like to install where one was installed at some point. The steam pipe is plugged with a 1/2 plug. I’ve hit it with heat for 1 minute and tried to open it with my wrench, no luck. I’m afraid to break the plug. Any suggestions?
And what is that bell shaped thing below the plug?
My replacement plan is a 1/2 close black nipple attached to a 1/2” female x 1” male fitting. That’s the best I could find in my hardware store. My radiator valve is 1” female.
