Because this pump can be wired for either 115V or 230V, the fitting provides a standardized connection point that remains stable regardless of the vibration or heat generated by the 1.5 HP motor. When installing, apply thread sealant or PTFE tape to the brass threads to prevent "galling" or seizing when it is screwed into the cast iron intake/discharge ports.

The brass fitting is a 1/4" NPT adapter designed specifically for mounting the pressure gauge or the pressure switch to the pump housing. It acts as a durable, corrosion-resistant interface between the cast iron pump body and the sensitive monitoring components, ensuring a leak-proof seal under high pressure.
