This clever device is used to test the nozzle operating pressure of any spray head, or any spray head with rotating nozzle. It has male threads on one end and female threads on the other each with their own built in shut off valve and key included. Use it with either female threaded bodies or male threaded bodies...just flip it over! If you need to test a fixed rotor head, bubbler, or drip emitter on 1/2" riser, just take the nozzle thread adapters off and you're ready to go.
Item is to be used with the Universal Pressure Gauge with schrader adapter.
