8 New Chrome Pipe Connectors Toilet Urinal

a slight mystery item. extremely nice shiney crome finish. 1/2 npt with a nut that has a rather large flange, other end looks like it mates to a tapered fitting - 1" id on the threads. taper goes from 0.762" to the end, slight chamfer on the end. 0.5520 id on that end. taper distance is about 0.3225". now in the center there is a 1/8" npt threaded port. these are slightly magnetic so i figure they are stainless steel maybe? if you know what these are please let us know, were extremely curious!
