Function of the Spray Nozzle

The MEG 1136 spray nozzle helps:

• Produce a 15° high-pressure fan spray
• Deliver aggressive cleaning power with controlled surface coverage
• Remove stubborn dirt, grease, mud, mildew, and heavy buildup efficiently
• Provide consistent spray distribution
• Maintain proper operating pressure and flow
• Deliver dependable OEM cleaning performance

Its 15° spray pattern is ideal for removing stubborn contaminants from concrete, heavy equipment, construction machinery, agricultural equipment, industrial equipment, and other durable surfaces that require more concentrated cleaning force.

Common Signs Replacement Is Needed

Replace the nozzle if you notice:

• Uneven or distorted spray pattern
• Reduced cleaning performance
• Worn or enlarged orifice
• Corrosion or physical damage
• Pressure loss caused by nozzle wear
• Inconsistent spray coverage

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

Installation & Service Notes

Turn off the pressure washer and relieve system pressure before changing nozzles.

Apply an appropriate thread sealant if required and install the 1/4" male NPT nozzle securely into a compatible spray wand or lance.

Tighten securely without overtightening.

Inspect the threaded connection regularly for leaks or wear.

Important: Match the 10.0 orifice size to your pressure washer's GPM and PSI specifications to maintain proper operating pressure and flow. The 15° spray pattern provides greater cleaning force than a 25° nozzle and is intended for durable surfaces. Exercise caution when cleaning painted finishes, vehicles, wood, glass, or other delicate materials that may be damaged by concentrated high-pressure spray.

Maintenance Recommendations

• Flush the nozzle with clean water after each use.
• Inspect the hardened stainless steel orifice regularly for wear or mineral buildup.
• Clean clogged nozzles using an approved nozzle cleaning tool—never use wire or sharp objects that may damage the precision orifice.
• Inspect the threaded connection for wear or damage.
• Store the nozzle in a clean, dry location when not in use.
• Use only genuine OEM MEG replacement nozzles to maintain proper spray pattern, operating pressure, and long-term performance.
