Product Description
Constructed with either lightweight hardcoat anodized aluminium or corrosion-resistant brass, the nozzle balances durability and maneuverability, ensuring reliable operation in harsh environments. It is fully NFPA 1964 compliant and meets European standards, with FM approval validating its performance and safety credentials. Designed for integration with Protek’s foam aeration tubes, this nozzle supports both water and foam firefighting applications, while offering configuration options of tip-only or shutoff playpipe combinations to suit diverse operational needs. Its laser-etched identifier and unique series number ensure easy tracking and compliance verification.
The nozzle’s robust build prioritizes longevity and resilience. Hardcoat anodized aluminium models reduce operator fatigue with their lightweight design (ideal for extended use), while corrosion-resistant brass variants excel in high-moisture or chemical-exposed environments, boasting superior tensile strength for heavy-duty applications . All units feature reinforced metal components and a heavy-duty chrome-plated shutoff ball, ensuring smooth operation and extended service life even under frequent use.
A stainless steel filter mesh prevents debris-induced blockages, maintaining consistent flow performance in challenging conditions. The raised lug pattern and laser-etched pressure markings (in both psi and bar) enhance visibility, allowing quick pattern identification and pressure monitoring during high-stress operations.
At its core, the nozzle delivers exceptional firefighting capabilities through its standard operating pressure of 100 psi (7 bar), with optional settings at 85 psi (6 bar) and 75 psi (5 bar) to adapt to varying water supply conditions. This flexibility ensures optimal flow rates across different scenarios, from intense industrial fires to controlled structural firefighting.
The wide fog pattern generated by precision-engineered spinning teeth provides superior heat deflection, protecting firefighters during interior attacks. Flow pattern detents enable positive positioning, ensuring consistent spray patterns without accidental adjustments. For added convenience, the nozzle supports flush operation without shutting down or altering the current pattern, allowing quick debris removal during critical operations.
Ergonomics take center stage with an improved pistol grip design, available in various colors for easy team identification. The smooth-action shutoff mechanism reduces hand strain, while the swivel inlet minimizes hose kinking during maneuvering. Each nozzle is laser-etched with a unique series number for traceability, simplifying inventory management and compliance audits.
This 2-1/2″ NST nozzle is engineered for versatility across professional firefighting scenarios:
• Industrial Facilities: Ideal for large-scale fires in manufacturing plants, chemical storage areas, and refineries, where its high flow capacity and foam compatibility address Class A and B fires .
• Municipal Firefighting: Supports structural fire response, offering adjustable patterns to navigate tight spaces or protect exposures with fog streams.
• Emergency Services: Trusted by rescue teams for its reliability in high-pressure environments, including wildland-urban interface fires and vehicle extrications.
• Marine & Offshore: Brass models excel in saltwater environments, providing corrosion resistance for shipboard or coastal firefighting applications .
While specific gallonage settings depend on pressure, the nozzle’s selectable design supports a wide range of flows, typically from 95 GPM to 200 GPM at standard operating pressures, making it suitable for both medium and high-volume firefighting .
Select aluminium for lightweight maneuverability in general firefighting. Choose brass for superior corrosion resistance in marine, chemical, or high-moisture environments, where durability under harsh conditions is critical .
Yes, all models work seamlessly with Protek’s foam aeration tubes, enabling aspirated foam applications for Class B flammable liquid fires.
The nozzle is fully NFPA 1964 compliant, meeting rigorous standards for performance and safety. It also holds FM approval and meets European standards, ensuring global operational compatibility .
Minimal maintenance is required thanks to its robust design. Regularly inspect the stainless steel filter mesh for debris, and lubricate the shutoff mechanism annually. The precision-machined components and corrosion-resistant materials reduce the need for frequent servicing .
This 2-1/2″ NST Selectable Gallonage Fire Hose Nozzle combines cutting-edge engineering with user-centric design, making it an indispensable tool for professional firefighters demanding reliability, versatility, and compliance in critical operations.
