Function of the Soaper Nozzle
The PNR 7681 soaper nozzle helps:
- Apply soaps and detergents evenly over large surfaces
- Produce a wide 65° fan spray pattern for maximum coverage
- Operate in low-pressure chemical application mode
- Increase detergent flow for high-GPM pressure washer systems
- Improve cleaning efficiency while reducing chemical waste
Its large 50.0 orifice is well suited for high-volume systems requiring greater chemical flow than standard soap nozzles.
Common Signs Replacement Is Needed
Replace the nozzle if you notice:
- Uneven spray pattern
- Excessive nozzle wear
- Reduced chemical flow
- Clogged orifice
- Damaged threads
- Corrosion or physical damage
- Poor detergent application performance
Replacing a worn nozzle helps maintain consistent spray coverage and efficient detergent application.
Installation & Service Notes
- Shut off the pressure washer and relieve system pressure before installation.
- Verify compatibility with the 1/4" MNPT connection and 50.0 orifice size.
- Apply thread sealant if recommended by the equipment manufacturer.
- Tighten securely without overtightening the brass threads.
- Flush the nozzle thoroughly with clean water after each use to remove chemical residue.
- Inspect the nozzle periodically for wear or blockage.
Important: This nozzle is designed for low-pressure chemical application only. The 50.0 orifice is intended for high-flow pressure washer systems and should be matched to the machine's GPM rating for proper detergent performance.
Maintenance Recommendations
- Rinse the nozzle thoroughly with clean water after every use.
- Inspect the orifice regularly for wear, mineral buildup, or debris.
- Clean clogged nozzles using an approved nozzle cleaning tool—avoid using wire or sharp objects that may 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 performance, chemical application efficiency, and long service life.
