High Volume Output: Delivers up to 43 GPM at 80 psi, enabling efficient watering of large areas and effective clean-ups.
Versatile Spray Patterns: Provides Fog, Jet Stream, and Fan patterns for a wide range of applications, from delicate misting to powerful rinsing.
Optimized for Commercial Use: Designed for high-pressure systems (70+ psi recommended) found in golf courses, sports fields, and commercial landscaping.
Complete Flow Shut-Off: Allows for precise water management, preventing waste and ensuring targeted application.
USA Made Quality: Manufactured in the USA, reflecting a commitment to high production standards and supporting local industries.
Model Number: NG550-DFH-75
Color: Black/Dark Red
Inlet Type: 3/4" Female Hose Thread (FHT)
Material: Aircraft Aluminum, Stainless Steel, TPR Rubber
Flow Rates (at 80 psi):
Low Flow: 12-17 GPM (45-64 L/min)
High Flow (Turbo Shift): 20-43 GPM (76-163 L/min)
Recommended Pressure: 70+ psi
Included in Product: The nozzle itself. Pistol grip or firefighter grip valves are sold separately.
Prepare Your Setup: Ensure you have a high-pressure water source (70 psi or above recommended) and a compatible high-flow hose. Attach your preferred pistol grip or firefighter grip valve (sold separately, models SV or SVPG) to the end of your hose.
Attach the Nozzle: Screw the 3/4" FHT inlet of the Underhill UltraMAX Turbo Shift Nozzle securely onto the outlet of your pistol grip or firefighter grip valve. Hand-tighten until snug, ensuring no leaks.
Adjust Flow and Spray Pattern:
Initiate Flow: Gently activate the ball valve on your grip to begin water flow. The nozzle will initially operate in the 12-17 GPM range, providing a light fog or low-volume jet stream.
Change Spray Pattern: Rotate the nozzle head to select your desired spray pattern: Fog for gentle coverage, Jet Stream for concentrated power, or Fan for broader coverage.
Engage Turbo Shift (High Flow): To access the higher flow range (20-43 GPM), adjust the nozzle's setting, which will "turbo shift" the water output to a significantly higher volume. This is typically achieved by a specific rotation or adjustment on the nozzle's collar.
Control Water Flow: Use the push-pull on/off control handle on your attached grip valve to precisely manage the water flow. Push forward to start flow and pull back to shut it off completely.
Store After Use: After completing your task, shut off the water supply at the source, drain any remaining water from the hose, and store the nozzle and grip in a clean, dry place to maintain their condition.
