Type: Suttner ST-456 5.5 Rotary Pressure Washer Nozzle – 5000 PSI Light Blue Turbo Nozzle

The Suttner ST-456 Rotary Pressure Washer Nozzle (Part #6467) is a genuine OEM turbo nozzle engineered to deliver superior cleaning performance for commercial and industrial pressure washing applications. Combining the concentrated power of a 0° spray with the wider cleaning coverage of a rotating spray pattern, the ST-456 quickly removes stubborn dirt, grease, mud, mildew, paint residue, and heavy buildup while cleaning larger surface areas more efficiently than a standard zero-degree nozzle.

Function of the Rotary Nozzle

The Suttner ST-456 helps:

• Produce a rotating high-impact spray pattern
• Combine the cleaning force of a 0° jet with wider cleaning coverage
• Remove stubborn dirt, grease, oil, mud, paint residue, and heavy deposits
• Increase cleaning speed while reducing operator fatigue
• Deliver consistent cleaning performance in demanding environments

Its rotating spray action provides significantly greater cleaning efficiency than conventional fan nozzles while reducing streaking and improving productivity.

Common Signs Replacement Is Needed

Replace the rotary nozzle if you notice:

• Loss of rotating action
• Reduced cleaning performance
• Uneven spray pattern
• Internal wear
• Water leakage
• Damaged threads
• Excessive vibration or unusual noise during operation

Replacing a worn rotary nozzle restores 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 nozzle rotation after startup to verify proper operation.
• Replace the nozzle if rotation becomes inconsistent or cleaning performance declines.

Important: Match the 5.5 nozzle size to your pressure washer's GPM and PSI specifications to maintain proper operating pressure and maximize cleaning performance. The ST-456 is intended for professional use on durable surfaces and should not be used on delicate finishes or materials that may be damaged by a high-impact rotating spray.

Maintenance Recommendations

• Flush the nozzle with clean water after each use.
• Inspect the rotating assembly regularly for wear or debris.
• Clean the nozzle if performance decreases—do not insert wire or sharp objects into the orifice.
• Store the nozzle in a clean, dry location when not in use.
• Use only genuine OEM Suttner replacement nozzles to ensure proper rotation, operating pressure, and long-term reliability.
