The monitor provides an undivided stream of water with minimum flow restriction over a wide operating pressure range. This ensures impressive performance with high flow rates and low trajectories. The monitor comprises essentially an inlet stand with lower and upper bend assemblies, and a threaded outlet enabling a variety of discharge nozzles to be utilised. Swivel joints have twin bearing races to ensure smooth operation, and a quad ring and an O-ring seals to prevent leaks. The flanged inlet enables locating the monitor on pipe-stands, hydrants, fire trucks, fire mains or towers.
