Plastic 1 1/2 inch nozzle with NPSH threads attached to a 1 1/2 inch aluminum female camlock with NPT threads.
How we conducted our nozzle testing
We used a Honda self-priming water pump with a two inch inlet and a two outlet that produces 135 gallons per minute (GPM). The nozzle was attached to a fifty foot 2 inch hose. The pump pressure was approximately 60 PSI. Gallons per minute was calculated by measuring the number of gallons a nozzle could fill a large container within one minute. The result is the GPM.
