AL-PLUG1/4MBSS | 1/4 M Quick-Connect Plug, Stainless

AL-PLUG1/4MBSS

The AR AL-PLUG1/4MBSS – 1/4″ Male Quick-Connect Plug is a premium stainless-steel fitting
engineered by Annovi Reverberi to deliver long-lasting, corrosion-resistant performance in high-pressure cleaning
systems. Designed for quick, secure, and leak-free connections, this plug lets operators attach and detach hoses,
spray guns, and accessories without tools, maintaining smooth workflow and consistent pressure in both commercial and
residential applications. Its 1/4-inch male quick-connect configuration fits standard female quick
couplers used throughout the pressure-washer industry, making it a universally compatible choice for demanding
environments.

Construction & Materials

Stainless-Steel Body

Constructed from precision-machined stainless steel, the AL-PLUG1/4MBSS offers superior resistance
to corrosion, abrasion, and chemical exposure compared with brass or plated fittings. Stainless steel’s strength and
non-reactive properties make it ideal for long-term use in hot- or cold-water systems, as well as marine, industrial,
and outdoor environments where moisture, salt, and detergents are common.

Precision Finish

Internal and external surfaces are finely polished to reduce friction and support smooth engagement with the mating
coupler. This precision machining helps maintain a tight, repeatable seal and leak-free performance even after
thousands of connect/disconnect cycles.

Quick-Connect Function

Fast, Tool-Free Coupling

The quick-connect mechanism is designed for effortless operation:

• Insert the plug into a compatible female coupler until it locks with a positive click.
• A pull on the coupler sleeve releases the plug for fast accessory changes.
• No threading, tape, or tools are required at the connection point.

This design reduces setup time, prevents thread wear or galling, and keeps changeovers simple when switching between
foam cannons, wands, rotary nozzles, or surface cleaners.

Performance & Reliability

High-Pressure Capability

The robust stainless-steel build provides a vibration-resistant connection that stays secure during extended
operation. Stainless steel’s high tensile strength withstands frequent pressure cycling and thermal expansion without
deformation, helping protect against fatigue cracking and seal compromise over time.

Smooth Flow Path

A smooth, straight-through bore promotes unrestricted water flow and minimizes pressure loss, helping
maintain pump efficiency and consistent nozzle output in high-performance washers, wash bays, agricultural systems,
and mobile rigs.

Corrosion Resistance

Harsh Environment Ready

The AL-PLUG1/4MBSS’s stainless-steel construction delivers long-term resistance to rust and pitting, even after
repeated exposure to aggressive detergents and outdoor conditions. Unlike plated fittings that can corrode once their
coating wears, stainless steel retains its protective properties throughout the life of the plug, making it suitable
for hot-water and steam-cleaning applications.

Reliable Sealing

Precision-machined sealing surfaces work with the coupler’s O-ring system to create a tight, reusable seal that
prevents leaks while still allowing smooth engagement and release.

Quality & Compatibility

AR Engineering Standards

Each AL-PLUG1/4MBSS is manufactured to Annovi Reverberi’s strict standards for fit, pressure tolerance, and cycle
life. Every plug is inspected for dimensional accuracy, surface finish, and hydraulic performance to ensure consistent
field behavior.

System Integration

The 1/4-inch male QC format makes this plug compatible with standard female quick couplers on hoses,
guns, and accessories across many brands. The compact size and ergonomic shape are easy to handle, even with gloves,
and fit well into confined spaces or integrated equipment frames.

Installation & Maintenance

Simple Setup

• Insert the male plug into a compatible 1/4″ female QC coupler until it snaps into place.
• Perform a tug test to confirm positive locking before pressurizing the system.
• Ensure the coupler’s O-ring is intact and lightly lubricated for optimal sealing and easy operation.

Low-Maintenance Operation

Maintenance requirements are minimal:

• Periodically clean the plug surface and coupler area to remove debris or chemical residue.
• Inspect the mating O-ring and replace it if worn, flattened, or cut.
• No coatings or special treatments are required thanks to stainless steel’s inherent corrosion resistance.
