Function of the Turbo Nozzle

The Hydra-Flex Aqua Rocket helps:

• Produce a high-speed rotating spray pattern
• Combine the impact of a concentrated 0° spray with broader cleaning coverage
• Remove stubborn dirt, grease, oil, mud, paint residue, mildew, and heavy buildup
• Increase cleaning speed while reducing operator fatigue
• Deliver consistent, professional-grade cleaning performance on demanding jobs

Its rotating spray action provides outstanding cleaning efficiency on durable surfaces while significantly reducing cleaning time compared to standard fan nozzles.

Common Signs Replacement Is Needed

Replace the turbo nozzle if you notice:

• Loss of rotating action
• Reduced cleaning performance
• Uneven or inconsistent spray pattern
• Internal wear
• Water leakage
• Damaged threads
• Excessive vibration or abnormal operating noise

Replacing a worn turbo nozzle restores maximum cleaning power, spray consistency, and overall pressure washer performance.

Installation & Service Notes

• Turn off the pressure washer and relieve system pressure before installation.
• Verify compatibility with the 1/4" FPT inlet and 5.5 nozzle size.
• Install the nozzle securely without overtightening the threads.
• Inspect threads and sealing surfaces before installation.
• Test the rotating spray after startup to verify proper operation.
• Replace the nozzle if rotation becomes inconsistent or cleaning performance declines.

Important: Match the 5.5 orifice size to your pressure washer's GPM and PSI specifications to maintain proper operating pressure and maximize cleaning performance. The Aqua Rocket Turbo Nozzle is intended for durable surfaces such as concrete, masonry, steel, heavy equipment, and industrial machinery. Avoid using the rotating high-impact spray on delicate finishes, painted surfaces, wood, glass, or other materials that could be damaged by concentrated pressure.

Maintenance Recommendations

• Flush the nozzle thoroughly with clean water after each use.
• Inspect the rotating assembly regularly for debris or signs of wear.
• Clean the nozzle if spray performance decreases—do not insert wire or sharp objects into the nozzle opening.
• Store the nozzle in a clean, dry location when not in use.
• Use only genuine OEM Hydra-Flex replacement parts to maintain proper rotation, operating pressure, cleaning efficiency, and long-term reliability.
