AL-PLUG1/4BRASS | 1/4 F Quick-Connect Plug, Brass

AL-PLUG1/4BRASS

The AR AL-PLUG1/4BRASS – 1/4″ Female Quick-Connect Plug is a precision-machined brass fitting
designed by Annovi Reverberi to provide fast, secure, leak-free connections in high-pressure cleaning systems.
Engineered for both professional and residential use, this plug enables effortless attachment and detachment of
hoses, spray guns, and accessories, streamlining setup and maintenance while delivering long-term reliability under
continuous operation. Its 1/4-inch female quick-connect configuration fits standard male couplers
found on most pressure washers, creating a universal connection point for a wide variety of tools used in surface
cleaning, vehicle washing, and industrial maintenance.

Construction & Materials

Solid Brass Body

Constructed entirely from solid brass, the AL-PLUG1/4BRASS offers outstanding durability, corrosion
resistance, and sealing precision. Brass’s natural resistance to oxidation and moisture ensures the fitting maintains
its integrity after repeated exposure to water, detergents, and harsh outdoor conditions. Unlike steel or plated
alternatives, brass resists rust and galling, making it ideal for long-term use in both hot- and cold-water
applications.

Precision Machining

Each plug is precision-machined to exacting tolerances to guarantee a consistent, tight seal when coupled with a
compatible quick-connect socket. The smooth internal bore allows unrestricted water flow, preserving
system efficiency and reducing turbulence that could affect nozzle performance or chemical draw.

Quick-Connect Function

Fast, Tool-Free Coupling

The AL-PLUG1/4BRASS is designed for convenience and speed:

• Simply insert the male coupler into the female plug until it clicks securely into place.
• A quick pull on the coupler sleeve releases the connection for rapid accessory changes.
• No tools or repeated threading are required, reducing setup time and thread wear.

This quick-connect design eliminates the need for threaded unions at the point of changeover, allowing operators to
move quickly between foam cannons, turbo nozzles, wands, and surface cleaners while maintaining full working
pressure.

Performance & Reliability

High-Pressure Capability

The robust brass construction enhances safety and performance in high-pressure environments. The fitting’s strength
and thermal stability allow it to withstand thousands of pressure cycles without deformation or leakage, even during
extended cleaning sessions.

Corrosion & Wear Resistance

Corrosion resistance and a polished brass surface help ensure:

• Smooth coupling engagement and disengagement without binding or sticking.
• Consistent operation when exposed to aggressive detergents and outdoor conditions.
• Long service life in both mobile rigs and stationary wash bays.

Quality & Compatibility

AR Engineering Standards

Annovi Reverberi’s quality control process verifies each AL-PLUG1/4BRASS plug for pressure tolerance,
dimensional accuracy, and flow performance. The precision-machined sealing surface and reinforced locking
groove ensure a firm, vibration-resistant fit that maintains hydraulic integrity during operation—especially when
paired with compatible AR quick couplers.

Wide System Integration

The 1/4-inch female quick-connect format makes this plug compatible with a broad range of pressure
washer accessories, pumps, and hoses across many brands. It is particularly useful where fast transitions between
tools are required while maintaining full working pressure, including:

• Car wash and detailing operations.
• Contractor and mobile cleaning rigs.
• Industrial and facility maintenance wash stations.
• Homeowner pressure-washing setups that demand pro-grade reliability.

The AL-PLUG1/4BRASS brass body also acts as a natural heat sink, helping dissipate thermal energy and protect internal seals over
long duty cycles.

Installation & Maintenance

Simple Setup

• Thread the M22 or hose-side coupler to the system as required, then snap the 3/8″ male QC side into the
  AL-PLUG1/4BRASS female plug.
• Confirm an audible click and perform a firm tug test before pressurizing.
• Ensure the mating coupler’s O-ring is intact and lightly lubricated with a non-reactive grease for best seal
  life and coupling action.

Low-Maintenance Operation

Maintenance is minimal:

• Periodically inspect the internal O-ring and sealing surfaces, cleaning away debris or scale.
• Apply a light, non-reactive lubricant to the O-ring as needed to maintain easy connect/disconnect action.
• Store in a dry or covered location when not in use; the corrosion-resistant brass does not require additional
  coatings.
