1-1/2" NST Viper Blue Devil Nozzle

Viper Blue Devil

Viper Blue Devil nozzles provide multiple flow selections and stream patterns while maintaining constant gallonage with all multiple flow and pattern settings.

General Applications

• Municipal and industrial firefighting use

Features & Advantages

• Flow Settings – The flow rate can be set through an easy grip ring featuring preset positions.


• Stream Pattern – The nozzle stream is adjusted by rotating the bumper giving the firefighter the widest fog pattern (Full Fog – Protection) to the narrowest fog pattern (Narrow Fog and Straight Stream).


• RYLSTATIC® Patented System – A system that gives you a uniform water fog with smaller water droplets and less friction loss than other traditional systems. Viper Blue Devil nozzles have been designed to offer a broader fog shield of protection to the firefighters.


• Shut Off Valve – The flow rate can be set through an easy grip ring featuring preset positions. The operation is smooth and constant allowing firefighters to open and close the valve easily. The valve has a dual seat and dual driven shaft to offer better performance against water hammers and to enhance its durability.


• Foam Use – The Viper Blue Devil nozzle can be used as a foam nozzle with the addition of the optional Foam Tube.


• Ring Markings – The flow rate can be set through an easy grip ring featuring preset positions. Markings on the flow selector ring and the pattern ring are laser engraved onto anodized aluminum to ensure they are easy to read and will not fade.


• Stainless Steel Inlet Screen- The flow rate can be set through an easy grip ring featuring preset positions. A stainless steel screen is mounted within the inlet to prevent material from entering the nozzle which reduces the risk of damage or failure during operation.


• Inlet Options – The swivel inlet allows the nozzle to rotate continuously while connected to the hose. Selectable flow nozzles are available with the following standard threads:
