American Radiator Co. Rococo - Identifying a Variation

TheClevelandSteamer · January 6

I have a American Radiator Co. Rococo radiator here. It's different than all the others I've seen. The top of each column is connected with the full-length rods, and they are just bolted together. They do not have the sealed threaded nipples like all the others I've seen.

Can anyone advise as to why this might be the case?

Thanks guys.

That radiator was made for steam heat only, not for hot water. Steam is lighter than air and will fill the sections even without the top connections.

They were probably a bit less costly to manufacture that way.

@bburd is right but that's not the whole story.

The original Rococo steam rads had rods at the bottom as well as the top, and were assembled with regular push nipples between the sections. Later they switched to right-and-left-hand threaded nipples and eliminated the rod on the bottom. Finally they eliminated the top rod as well. This one is the second version.

i was about to ask, if the bottom had a rod because I didn't see it.
