Fleck 5600 Yoke 3/4

1″ Yoke Male Plastic used instead of metal by pass, or used with plastic by pass. Diameter on female side ( that faces / couples to the Valve Body or Plastic By Pass, 60049 ), is the same for both 3/4″ or 1″ Yoke = 1″ inner diameter. Connects to the Valve Body using the clips that come with the Valve. That would be either “adapter couplers” – sold separately, or meter modules usually have clips and screws for attaching.
