Function of the Spray Nozzle

The PNR 7671 spray nozzle helps:

• Produce a concentrated 0° high-pressure pinpoint stream
• Deliver maximum cleaning force on stubborn dirt, grease, mud, and heavy buildup
• Focus water pressure on small target areas for precision cleaning
• Maintain consistent operating pressure and water flow
• Improve cleaning performance on hard, durable surfaces

Its 0° spray pattern delivers the highest impact of any standard pressure washer nozzle, making it ideal for heavy-duty cleaning and surface preparation where concentrated cleaning power is required.

Common Signs Replacement Is Needed

Replace the nozzle if you notice:

• Reduced cleaning pressure
• Worn or enlarged orifice
• Irregular or distorted water stream
• Clogged nozzle
• Damaged threads
• Corrosion or physical damage
• Increased water consumption due to nozzle wear

Replacing a worn nozzle restores proper pressure, stream accuracy, and cleaning efficiency.

Installation & Service Notes

• Turn off the pressure washer and relieve system pressure before replacing the nozzle.
• Verify compatibility with the 1/4" MNPT connection and 8.0 orifice size.
• Install the nozzle securely without overtightening the stainless steel threads.
• Inspect the nozzle seat and threads for debris before installation.
• Test the spray stream after installation to confirm proper operation.
• Replace the nozzle if wear causes pressure loss or an inconsistent stream.

Important: The 0° spray pattern produces a highly concentrated stream with maximum impact. Use caution to avoid damaging painted, finished, wood, soft stone, or other delicate surfaces. Always match the 8.0 orifice to your pressure washer's GPM and PSI specifications to maintain proper operating pressure and safe performance.

Maintenance Recommendations

• Flush the nozzle with clean water after each 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 may enlarge the precision orifice.
• Store the nozzle in a clean, dry location when not in use.
• Use only genuine OEM replacement nozzles to maintain proper spray pattern, operating pressure, and long service life.
