AL-QC3/8BSS | 3/8″ Quick-Connect Coupler, Stainless

Overview

The AR AL-QC3/8BSS – 3/8″ Quick-Connect Coupling (3/8″ F x 3/8″ F, Stainless Steel)
is a heavy-duty stainless-steel fitting from Annovi Reverberi, engineered to deliver superior corrosion resistance,
high-pressure sealing, and long-term reliability in demanding cleaning environments. With its dual
3/8″ female x 3/8″ female configuration and one-handed quick-connect mechanism, this
coupler allows fast, tool-free connection of hoses, spray guns, and accessories, ensuring secure and leak-free
operation in professional, industrial, and commercial pressure washer systems.

Construction & Materials

All-Stainless-Steel Body

Constructed entirely from solid stainless steel, the AL-QC3/8BSS offers outstanding resistance to
rust, oxidation, and chemical corrosion—far exceeding the performance of brass or plated alternatives. Stainless
steel’s high tensile strength and toughness help the coupler maintain structural integrity under heavy loads and
pressure fluctuations, even during continuous use.

Precision Machining & Finish

Each fitting is precision-machined for a perfect fit, consistent geometry, and smooth coupling engagement. The
polished stainless finish enhances appearance, reduces friction during connection, and resists buildup of dirt,
detergents, and mineral residue over time.

Quick-Connect Operation

Fast, Tool-Free Coupling

The quick-connect mechanism is engineered for ease and reliability:

• Insert a compatible 3/8″ male plug into the coupler until it locks firmly with an audible click.
• The locking action forms an immediate, watertight seal capable of withstanding high PSI pressures.
• To disconnect, simply pull back the sleeve to release the plug—no tools or thread work required.

This one-handed, tool-free operation saves time during setup and accessory changes while preventing thread damage
common with traditional fittings. The secure locking system delivers a vibration-proof connection that resists
leaks and accidental disconnections in the field.

Flow & Sealing Performance

Smooth Internal Flow Path

Internally, the AL-QC3/8BSS features precision-engineered sealing surfaces and a smooth flow path to minimize
turbulence and maintain full water pressure and flow rate. This preserves cleaning efficiency and protects pumps,
hoses, and nozzles from performance-robbing pressure loss.

High-Quality O-Ring Sealing

High-quality, temperature- and chemical-resistant O-rings provide long-term sealing performance
even when exposed to hot water, detergents, or solvents. The rigid stainless-steel body resists fatigue and keeps
the sealing lands perfectly aligned under stress, ensuring reliable, leak-free operation through thousands of
connection cycles.

Configuration & Integration

3/8″ F x 3/8″ F Versatility

The dual 3/8″ female x 3/8″ female layout provides broad versatility:

• Link hoses in series to extend reach without extra adapters.
• Bridge between hose ends and tools that share a 3/8″ male quick-connect plug.
• Standardize fleets and bays around a common 3/8″ QC interface for faster reconfigurations.

The non-swiveling, fixed-body construction ensures mechanical stability under continuous high pressure, while the
hexagonal profile offers a secure grip for tightening by hand or with a wrench.

Durability in Harsh Environments

Corrosion & Heat Resistance

Because stainless steel is highly resistant to corrosion and scaling, this coupler remains clean and functional
even in harsh outdoor, marine, or chemical environments. Its high-strength design is suitable for hot-water and
steam applications where brass couplers may soften or degrade over time.

Low-Maintenance Design

Maintenance is minimal: periodic cleaning of coupling surfaces and inspection of the O-ring are generally all that
is required. A light application of compatible lubricant on the O-ring can enhance longevity and maintain smooth
engagement. Stainless steel requires no protective coatings and will not peel, flake, or rust with age.

Quality Assurance

Each AL-QC3/8BSS coupler is manufactured to Annovi Reverberi’s exacting standards and undergoes extensive quality
control testing for dimensional accuracy, pressure endurance, and leak integrity. The result is a fitting that
provides long-lasting performance and reliability in commercial cleaning systems, industrial wash bays, agricultural
sprayers, and mobile pressure-washing rigs.

Summary

The AR AL-QC3/8BSS – 3/8″ Quick-Connect Coupling (3/8″ F x 3/8″ F, Stainless Steel)
represents the pinnacle of Annovi Reverberi’s coupling technology. By combining solid stainless-steel construction,
precision quick-connect engineering, and superior corrosion resistance, it delivers:

• Secure, leak-free connections under continuous high pressure.
• Fast, tool-free hose and accessory changes.
• Long-term durability in high-moisture and chemically aggressive environments.

Designed to endure years of heavy-duty service, this coupler ensures consistent water flow, corrosion-proof
connections, and effortless quick-change functionality for high-pressure cleaning systems operating in the
toughest conditions.
