Plastic 1 1/2 inch combination nozzle has the option of a straight stream or a fog pattern with D-Handle pistol grip shut-off. NPSH and NPT are more common in industrial applications.
How we conducted our nozzle testing.
We used a Honda self-priming water pump with a two inch inlet and a two inch outlet that produces 135 gallons per minute (GPM). The nozzle was attached to a fifty foot 1 1/2 inch fire 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.
