1-1/4 X 1" Valve reducer, 1-1/4 B x 1F brass camlocks with brass full flow valve, machined zinc plated steel taper reducer, and 600 psi full flow 1" valve. This reducer is typically used for alum injection of fireproofing. It allows the upstream material to be blocked off so that the alum injection pump can be used to push out a pack in the whip line. It also could be used in other applications to stop the flow of material after shutting the pump off so that the gun could be changed more easily.
