Common Signs Replacement Is Needed

Replace the nozzle if you notice:

• Uneven or distorted spray pattern
• Reduced cleaning performance
• Worn or enlarged orifice
• Damaged quick-connect plug
• Cracked or damaged protective guard
• Corrosion or physical damage
• Pressure loss caused by nozzle wear

Replacing a worn nozzle restores proper spray pattern, operating pressure, and cleaning efficiency.

Installation & Service Notes

• Turn off the pressure washer and relieve system pressure before changing nozzles.
• Insert the integrated 1/4" quick-connect plug fully into a compatible quick-connect coupler until securely locked.
• Align the spray pattern using the molded locating ribs on the nozzle guard.
• Verify the nozzle is securely seated before operating the pressure washer.
• Inspect the quick-connect fitting and O-rings regularly for wear or damage.

Important: Match the 4.5 orifice size to your pressure washer's GPM and PSI specifications to maintain proper operating pressure and cleaning performance. The 25° spray pattern provides an excellent balance of cleaning power and wide coverage, making it a preferred nozzle for contractors and general-purpose pressure washing applications.

Maintenance Recommendations

• Flush the nozzle with clean water after each use.
• Inspect the hardened stainless steel orifice regularly for wear or mineral buildup.
• Clean clogged nozzles using an approved nozzle cleaning tool—never use wire or sharp objects that may damage the precision orifice.
• Inspect the quick-connect plug and protective guard for signs of wear or damage.
• Store the nozzle in a clean, dry location when not in use.
• Use only genuine OEM QC-MEG replacement nozzles to maintain proper spray pattern, operating pressure, and long-term performance.
