AR4220690 QC Soap Nozzle Black Tip | 1/4 inch Plug

AR4220690 – QC Soap Nozzle — Black Tip, 1/4 in Quick-Connect

Overview

The AR AR4220690 QC Soap Nozzle — Black Tip, 1/4 in Quick-Connect is a
specialized low-pressure detergent nozzle engineered by Annovi Reverberi to deliver wide,
consistent spray coverage for soaps and chemicals in pressure-washing systems. It lets operators
switch quickly from high-pressure rinsing to low-pressure chemical application for efficient
soft-wash cleaning.

• Low-pressure nozzle for detergent and chemical application.
• Wide fan pattern for fast coverage of large surface areas.
• Ideal for soft washing, pre-treating, and general detergent lay-down.

Construction & Durability

Built from corrosion-resistant stainless steel and heavy-duty polymer, the AR4220690 is designed
for long service life in chemical and outdoor environments.

• Stainless steel core resists wear from water and detergents.
• Chemical-resistant polymer tip stands up to alkaline and neutral cleaners.
• Precision-machined orifice delivers smooth, even flow without pulsation.
• Internal geometry is designed to minimize clogging and turbulence.

Spray Pattern & Soap Delivery

The black tip follows the standard pressure-washer color code, indicating a dedicated soap
nozzle with a very wide low-pressure pattern.

• Produces an approximate 65° spray angle for broad, gentle coverage.
• Low-pressure fan protects delicate surfaces like paint, vinyl siding, and wood.
• Ensures even detergent lay-down for effective dwell and soil breakdown.
• Reduces streaking and uneven chemical application compared to narrow jets.

1/4 in Quick-Connect Compatibility

A standard 1/4 in quick-connect plug makes the AR4220690 easy to use with most professional and
consumer pressure-washer guns and lances.

• Snaps into standard 1/4 in quick-connect couplers in seconds.
• Secure, leak-free engagement for reliable operation under typical system pressures.
• Compatible with most residential, commercial, and industrial pressure-washer brands.
• High-strength stainless or brass plug resists wear from frequent tool changes.

Operation with Chemical Injectors

The AR4220690 is optimized for downstream chemical injectors that feed detergent into the water
stream at low pressure.

• Low-pressure design activates downstream injectors for proper chemical draw.
• Mixes soap and water uniformly for consistent solution strength.
• Eliminates the need for manual pre-mixing or separate pump systems.
• Supports efficient, on-demand switching between rinse and soap modes.

Applications & Use Cases

With its gentle, wide-coverage spray, this nozzle excels anywhere soft-wash techniques and even
detergent coverage are required.

• Vehicles and equipment — cars, trucks, buses, trailers, and machinery.
• Building exteriors — siding, stucco, brick, and storefronts.
• Roofs, gutters, and soffits where high pressure could cause damage.
• Decks, fences, patios, and other surfaces needing chemical pre-treatment.

Flow Design & Efficiency

Internal flow passages are engineered to provide smooth, efficient chemical delivery while
minimizing waste.

• Low turbulence path maintains stable soap concentration from start to finish.
• Consistent fan pattern helps reach corners, joints, and recesses.
• Reduces overspray and chemical runoff for more efficient product use.
• Supports environmentally conscious cleaning by minimizing detergent waste.

Maintenance

Routine care keeps the AR4220690 performing at peak levels for years.

• Flush with clean water after each use to remove detergent residue.
• Clear any crystallization or debris with a nozzle cleaning tool or pin.
• Chemical-resistant materials maintain performance after repeated soap exposure.
• Designed to handle typical system pressures during transitions between soap and rinse.

Summary

The AR AR4220690 QC Soap Nozzle — Black Tip, 1/4 in Quick-Connect delivers the
wide coverage, reliable low-pressure performance, and fast tool-change convenience needed for
professional-grade detergent application. Compact, corrosion-resistant, and precision-calibrated,
it enhances the versatility of any pressure-washing system—making soft washing, pre-treating, and
chemical application faster, safer, and more effective for both professionals and homeowners.
