The inlet and discharge threading on the Flow Max RV Fresh Water Pump - 12 Volt # LC689052 is .825 inches using a digital caliper so it is not the 1/2 inch male national pipe thread which would be .840 inches. Lippert recommends using the barb fittings included and using 1/2 inch inner diameter flexible hose. My contact said they use the odd size to protect the pump from over-tightening and possible cracking of the housing. The fittings are designed to only be hand tight.
