Automatic pressure control with a flow capacity of 95-300 gpm (360-1150 l/min). Includes flush without shutting down, molded rubber teeth for full-fill "power fog", and turbulence-free flow control. Lightweight hard coat anodized aluminum materials for maximum resistance to corrosion and wear. 2.5" NH (64mm) rigid rocker lug coupling is standard. Tip does not shut off and must be used with a separate valve or valved playpipe. Nozzle may be switched between standard 100 psi (7 bar) and low pressure.
