HYDRANT EXHAUST The Hydrant Air Exhaust (HAX) uses the technology of an Air Release Valve to make filling you water lines easy and with out flooding the area. The once, time consuming, task of babysitting the hydrant is now over! Simply install the HAX and come back when the system is fully pressurized and all the air is gone!

ADVANCED FEATURES Its multi-port design makes pressure testing and water quality testing possible in areas that were not possible under your current system. Use the HAX to relieve air when you find pressure spikes in your system.  The HAX uses a solid stainless steel body that is rated to withstand pressures up to 250 PSI  Great for additional testing anywhere there is a fire hydrant.
