Function of the Spray Nozzle

The PNR 7658 spray nozzle helps:

• Produce a concentrated 15° high-pressure fan spray
• Deliver ultra-high water flow with aggressive cleaning power
• Remove stubborn dirt, grease, oil, mud, scale, and heavy buildup
• Maintain consistent operating pressure and water flow
• Improve cleaning productivity on demanding commercial and industrial applications

Its 15° spray pattern and 60.0 orifice are designed for ultra-high-flow pressure washer systems requiring concentrated cleaning force on heavy equipment, industrial machinery, construction equipment, agricultural machinery, and other durable surfaces.

Common Signs Replacement Is Needed

Replace the nozzle if you notice:

• Uneven or distorted spray pattern
• Reduced cleaning pressure
• Worn or enlarged orifice
• Clogged nozzle
• Damaged threads
• Corrosion or physical damage
• Increased water flow caused by nozzle wear resulting in pressure loss

Replacing a worn nozzle restores proper spray pattern, operating pressure, and overall cleaning performance.

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 60.0 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 pattern after installation to verify proper operation.
• Replace the nozzle if wear causes pressure loss or an inconsistent spray pattern.

Important: Match the 60.0 orifice size to your pressure washer's GPM and PSI specifications to maintain proper operating pressure and cleaning performance. The 15° spray pattern is intended for durable surfaces and heavy-duty cleaning applications. Use caution when cleaning painted finishes, vehicles, wood, glass, or other delicate materials that may be damaged by concentrated pressure.

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 or damage 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.
