I replaced my old recirculation pump with a newer model. The new model uses these union joints so that if I ever need to remove and replace the pump it will be much easier. Seemed a bit pricy though.

This kit worked PERFECTLY to connect up the pump AND make it super easy to remove/replace/evacuate air via the shut-off valves. The machined surfaces are perfectly flat and the flat rubber gaskets work well to seal up the connections with very little torque. Use these kits without hesitation. And do pay attention to the type of connection you are purchasing. This one is the 3/4" NPT thread as it is clearly stated.
