Baseboard heating element fitting

KME Member Posts: 3
Can anyone identify this fitting?  It's cast bronze, reduces from 3/4" copper to 1/2".  The long taper and the pins on the side make me wonder if it's something other than a cast tapered reducer.

    The pins are probably just a part of the casting process that didn't get cleaned off in the sand tumbler. If it were something like a balance valve, there'd be a packing gland and a machined shaft where the pins are located.

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.

    My vote is that it is a combination expansion-reducing joint. I bet the pin is a part of a length limiting system.
