The Aquapro Union Adapter Kit with O-Ring is specifically manufactured for use with Aquapro PurFlo Pumps. The union side/nut measures 3-1/8" female threads with 1-3/4" female threads on the other opening. The 1-3/4" female threads accept 1-1/2" male threaded fittings even though the actual measurement is slightly larger.
The total length of the union kit is 3-3/8".
