Function of the Soap Nozzle

The VeeJet 4040 Soaper Nozzle helps:

• Apply detergents and cleaning chemicals at low pressure
• Maximize downstream chemical injector performance
• Provide even chemical distribution across large surfaces
• Improve cleaning efficiency before pressure rinsing
• Reduce chemical waste through consistent application
• Deliver dependable OEM performance

Its 40.0 orifice is specifically designed for downstream soap application, allowing detergents and cleaning solutions to be applied safely before switching to a high-pressure cleaning nozzle for rinsing.

Common Signs Replacement Is Needed

Replace the nozzle if you notice:

• Poor detergent draw
• Uneven chemical application
• Worn or enlarged orifice
• Corrosion or physical damage
• Reduced downstream injector performance
• Clogged nozzle opening

Replacing a worn soap nozzle restores proper chemical application and overall cleaning efficiency.

Installation & Service Notes

Turn off the pressure washer and relieve system pressure before changing nozzles.

Apply an appropriate thread sealant if required and install the 1/4" male NPT nozzle securely into a compatible spray wand or lance.

Tighten securely without overtightening.

Inspect the threaded connection regularly for leaks or wear.

Important: The VeeJet 4040 Soaper Nozzle is designed for low-pressure downstream detergent application and should be used with compatible downstream chemical injector systems. It is not intended for high-pressure cleaning applications.

Maintenance Recommendations

• Flush the nozzle thoroughly with clean water after each use to remove detergent residue.
• Inspect the orifice regularly for mineral buildup or debris.
• Clean clogged nozzles using an approved nozzle cleaning tool—never use wire or sharp objects that may damage the precision orifice.
• Inspect the threaded connection for wear or corrosion.
• Store the nozzle in a clean, dry location when not in use.
• Use only genuine OEM Spraying Systems Co. replacement nozzles to maintain proper detergent application and long-term performance.
