Function of the Soaper Nozzle
The PNR 7660 soaper nozzle helps:
- Apply detergents and cleaning chemicals at low pressure
- Produce a concentrated 25° fan spray pattern
- Deliver maximum chemical flow for high-GPM systems
- Improve detergent penetration on stubborn dirt and grime
- Increase cleaning efficiency while minimizing chemical waste
Its 60.0 orifice and focused 25° spray pattern make it ideal for professional cleaning applications that require higher detergent output and targeted chemical application.
Common Signs Replacement Is Needed
Replace the nozzle if you notice:
- Uneven spray pattern
- Reduced chemical flow
- Worn or enlarged orifice
- Clogged nozzle
- Damaged threads
- Corrosion or physical damage
- Poor detergent application performance
Replacing a worn nozzle restores proper chemical flow and consistent spray performance.
Installation & Service Notes
- Shut off the pressure washer and relieve system pressure before installation.
- Verify compatibility with the 1/4" MNPT connection and 60.0 orifice size.
- Apply thread sealant if recommended by the equipment manufacturer.
- Tighten the nozzle securely without overtightening the brass threads.
- Flush the nozzle thoroughly with clean water after each use to remove detergent residue.
- Inspect the nozzle periodically for wear or blockage.
Important: This nozzle is intended for low-pressure chemical application only and should be used with compatible downstream chemical injector systems or pressure washer soap mode settings. The 60.0 orifice is designed for very high-flow pressure washer systems and should be matched to the machine's GPM rating for optimum detergent performance.
Maintenance Recommendations
- Rinse the nozzle thoroughly with clean water after every use.
- Inspect the orifice regularly for mineral deposits, debris, or wear.
- Clean clogged nozzles using an approved nozzle cleaning tool—avoid using wire or sharp objects that can enlarge the orifice.
- Store the nozzle in a clean, dry location when not in use.
- Use only genuine OEM replacement nozzles to maintain proper spray pattern, chemical application efficiency, and long service life.
