Function of the Soaper Nozzle
The PNR 7618 soaper nozzle helps:
- Apply detergents and cleaning chemicals at low pressure
- Produce a wide 65° fan spray pattern for broad coverage
- Deliver consistent chemical flow for lower-GPM pressure washer systems
- Improve detergent penetration before pressure rinsing
- Increase cleaning efficiency while reducing chemical waste
Its combination of a 10.0 orifice and 65° spray angle makes it ideal for quickly applying detergent over large surfaces while maintaining proper chemical distribution.
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 spray coverage and consistent chemical application.
Installation & Service Notes
- Shut off the pressure washer and relieve system pressure before installation.
- Verify compatibility with the 1/4" MNPT connection and 10.0 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 regularly 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. Match the 10.0 orifice to your pressure washer's GPM rating to ensure proper detergent draw and application.
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.
