The Underhill Magnum NG450 is a heavy-duty, precision-machined hose nozzle engineered for professional turf, sports-field and equipment use. Built with solid metal internals and a smooth ratchet-adjust head, the Magnum delivers reliable performance in high-demand applications.

  • All-metal internals: No plastic parts to break, stick, or wear out—designed for long service life.
  • Ratchet mechanism: Positive click stops prevent over-tightening while allowing quick adjustment between spray patterns.
  • Adjustable spray patterns: Easy transition from a gentle fan to a powerful jet for watering, cleaning, or spot treatment.
  • High flow performance: Rated at approximately 37 GPM (140 L/min) at 80 PSI for fast coverage and efficient wash-down.
  • Standard inlet: 3/4 in hose thread (FHT) fits garden hoses; 1 in adapter options are offered by some suppliers.
  • Durable materials: Precision-machined brass, stainless steel, aluminum/zinc alloy components and Sanopreme®/TPR rubber seals resist wear and corrosion.

Precision spray control, fire-hose quality feel, and rugged construction make the NG450 well suited for golf greens, athletic fields, landscape irrigation and heavy-duty equipment wash-down.
