The Underhill GNA-75 PowerBlast MultiMax adjustable nozzle delivers compact, high-pressure performance in a machined-brass body. Built for durability and precise control, this 4" nozzle fits standard 3/4" FHT hoses and adjusts easily from a fine mist to a concentrated jet for cleaning, watering, or equipment wash-downs.

  • Solid machined-brass construction for corrosion resistance and long service life.
  • 3/4" FHT inlet fits common garden hoses and turf applications.
  • Adjustable spray patterns — twist to select fine mist, fan/soak, or powerful jet.
  • Efficient flow rated at 7 GPM at 80 PSI for strong cleaning power with controlled water use.
  • Compact 4" length offers easy handling and storage on hose racks or reels.
  • Leak-resistant design minimizes waste and improves reliability under repeated use.

Ideal for contractors, landscapers, and homeowners, the GNA-75 combines industrial-grade materials with simple, twist-to-adjust operation. Install by threading the nozzle onto any standard 3/4" male hose end until hand-tight. To extend life, rinse debris after use and store indoors during freezing temperatures.
