Brass 1 inch NPSH threaded smooth bore nozzle with satin finish is a straight stream only with no shut-off.
NPSH and NPT is common in industrial applications. NH/NST is common in the fire service.
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 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.
