These are the perfect tool for troubleshooting your pop-up system, they allow for to to connect a pressure gauge in between your pop-up nozzle body and check the operating pressure of your system at the nozzle.Ideally your Hunter MP Rotator or Rain Bird R-VAN should run at around 300kpa & a Spray Nozzle should run at around 200kpa for optimum performance. If your pressure is to low the sprinkler will not throw the required distance and the droplets will be to heavy. If the pressure is excessively high the sprinkler will mist and blow away in a slight breezeAvailable as an adaptor only or as a kit including a pressure gauge
