Hydrant Diffuser

A hydrant diffuser offers quick and efficient hydrant flow testing.  The 2½" hydrant diffusers use a dual function, liquid filled gauge, which measures both gallons per minute as well as PSI.  They also feature a 2½" female NST swivel so that when connected to the hydrant, the water flow can be aimed in a desirable direction as to not disturb landscape or damage objects in the waters path.  We have various 4½" models as well for the steamer side of a fire hydrant.
