Simpler, more accurate fire hydrant flow tests are possible with the Inspector's Hydrant Flow Nozzle!
Made of nickel-plated brass, this 6" long smooth-bore nozzle features a 2 1/4" inner diameter tube delivering a constant 0.88 coefficient of flow between 10 and 56 PSI.
Features a waterproof decal affixed to the tube highlighting the actual GPM between 10 and 56 PSI.
Stop estimating a coefficient during your flow tests and jump right to the results.
NST or Ontario 5TPI threads available.
Pairs nicely with the Brass Flow Nozzle Elbow and works perfectly with any of our Pitot Gauge Kits.
