4″ – 4½″ Hose Monster®

The 4″ and 4 ½″ Hose Monster® are designed for flow testing large-capacity systems and unidirectional flushing through the steamer/pumper port of a hydrant.

  • 4″  Approved Flow range:  1,074 GPM to 2,842 GPM.
  • 4½″ Approved Flow range:  1,047 GPM to 2,770 GPM.

Both units are constructed of steel and include a precision-machined internal orifice plate for accurate and consistent flow rate measurements.  The rugged steel orifice plate means that a flow test will never be interrupted due to rocks and flushing debris damaging a pitot.
