AL-PLUG3/8MB | 3/8 M Quick-Connect Plug, Brass

AL-PLUG3/8MB

The AR AL-PLUG3/8MB – 3/8″ Male Quick-Connect Plug is a durable, precision-machined brass fitting
designed by Annovi Reverberi to provide fast, secure, and leak-free connections in professional and residential
high-pressure washer systems. Engineered for reliability and ease of use, it lets operators connect and disconnect
hoses, spray guns, and accessories without tools, reducing downtime and improving efficiency. Its
3/8-inch male quick-connect configuration matches standard female couplers across most major
pressure-washer brands, making it an essential component for users who require dependable performance under continuous
high-pressure operation.

Construction & Materials

Solid Brass Body

Constructed from solid, corrosion-resistant brass, the AL-PLUG3/8MB delivers long-lasting strength
and stability in demanding cleaning environments. Brass resists rust, oxidation, and pitting while offering excellent
thermal and mechanical properties, making it a preferred material for high-pressure fittings in both hot- and
cold-water systems.

Precision Machining

The plug’s precision-machined sealing and locking surfaces provide a tight, repeatable fit that maintains a
watertight seal and prevents leaks, even after thousands of connection cycles. Brass’s natural resistance to chemical
corrosion supports regular use with detergents and cleaning solutions without degrading performance.

Quick-Connect Operation

One-Handed Coupling

A one-handed quick-connect mechanism allows instant attachment and release:

• Push the plug into a compatible 3/8″ female coupler until it clicks firmly into place.
• The connection forms a tight, leak-proof joint capable of withstanding high operating pressures.
• To disconnect, pull back the coupler sleeve—no wrenches or threading are required.

This instant-connect design lets users switch quickly between foam cannons, turbo nozzles, surface cleaners, and
other tools, improving workflow efficiency during complex cleaning tasks.

Performance & Reliability

Smooth Flow & Pressure Retention

Internally, the AL-PLUG3/8MB’s smooth bore is optimized for unrestricted water flow, minimizing turbulence and
helping maintain maximum pump performance and consistent nozzle output. The precision-fit locking groove works with
the coupler’s O-ring to deliver excellent pressure retention, supporting steady spray patterns and reducing pressure
drop that can compromise cleaning performance.

Stable Under Vibration

The compact design maintains stability under vibration and movement, while the robust brass body absorbs pressure
fluctuations without deforming or loosening. A fixed, non-swivel construction provides long-term mechanical stability
and reduces the risk of fatigue or loosening at the joint, even in mobile rigs and industrial settings.

Installation & Compatibility

Hex Base for Easy Handling

The AL-PLUG3/8MB features a hexagonal base that provides a secure grip for installation and removal,
allowing users to achieve a tight seal without overtightening. The compact form factor fits easily into tight panels
or integrated manifolds without adding excess length or weight.

System Integration

Compatible with a wide range of AR quick-connect couplers and other industry-standard fittings, this plug integrates
seamlessly into existing hose and gun setups. Its ability to withstand high PSI levels makes it suitable for
professional contractors, automotive detailers, agricultural cleaning, equipment maintenance, and serious residential
use.

Maintenance & Service Life

Simple Care

Maintenance is straightforward:

• Periodically clean the plug’s exterior and mating surfaces.
• Inspect the O-ring inside the female coupler to ensure it remains intact and flexible.
• No special coatings or treatments are required—brass naturally resists corrosion.

The polished finish promotes smooth engagement and disengagement without sticking, even after extended service life.

Tested to AR Standards

Each AL-PLUG3/8MB is tested for leak prevention, pressure retention, and mechanical precision before leaving the
factory, ensuring consistent performance and operator safety in high-pressure environments.
