AL-QC1/4B | 1/4 F x 1/4 F Quick-Connect Coupler, Brass

AL-QC1/4B

The AR AL-QC1/4B – 1/4″ F x 1/4″ F Quick-Connect Coupler is a precision-engineered brass
fitting from Annovi Reverberi, designed to deliver secure, leak-free, and high-efficiency connections in professional
and residential pressure washer systems. Featuring dual 1/4-inch female quick-connect ports, this
coupler lets users join hoses, spray guns, and accessories quickly and securely, eliminating the delays and wear
associated with traditional threaded connections. Its quick-connect mechanism supports fast setup, reliable sealing,
and easy maintenance—ideal for high-pressure cleaning applications that demand dependable performance and frequent
accessory changes.

Construction & Materials

Solid Brass Body

Constructed from solid, high-quality brass, the AL-QC1/4B delivers excellent durability, corrosion
resistance, and mechanical strength under continuous high-pressure operation. Brass naturally resists oxidation, rust,
and chemical damage while maintaining precise geometry and sealing performance across thousands of use cycles.

Precision-Machined Interfaces

The precision-machined internal sealing surfaces and dual 1/4″ female quick-connect interfaces ensure a tight,
vibration-resistant fit that prevents leaks and pressure loss during operation. Heavy-duty construction allows the
coupler to withstand demanding environments—from fixed wash bays to mobile detailing rigs—without deformation or
performance drift.

AL-QC1/4B Quick-Connect Operation

Fast, Tool-Free Hookups

The AL-QC1/4B is engineered for fast, efficient use:

• Insert a compatible 1/4″ male plug into the coupler until it locks securely with a positive click.
• The locking mechanism forms an immediate, watertight seal capable of handling high operating pressures.
• To disconnect, simply pull back the coupler sleeve to release the plug—no wrenches or threading required.

This one-handed, tool-free operation reduces setup time and minimizes thread wear, making it ideal for users who
frequently swap between spray nozzles, foam cannons, surface cleaners, and pressure guns.

Performance & Flow Characteristics

Optimized Internal Flow Path

Internally, the AL-QC1/4B is designed for maximum water flow and pressure retention. The smooth bore and precision
sealing surfaces minimize turbulence and restriction, helping preserve the system’s full operating pressure and flow
rate so nozzles perform as intended.

Durable O-Ring Sealing

The coupler uses internal O-rings made from temperature- and chemical-resistant materials to provide
long-lasting sealing performance. These seals withstand hot water, detergents, and frequent pressure cycling while
maintaining a tight, leak-resistant interface. The secure locking mechanism holds the connection firmly in place,
preventing accidental disconnections even under vibration and continuous use.

Configuration & Compatibility

1/4″ F x 1/4″ F Versatility

With its 1/4″ female x 1/4″ female layout, the AL-QC1/4B serves as a versatile connection
hub between hoses, lances, and quick-change tools equipped with matching male plugs. It integrates seamlessly into
most professional and consumer pressure-washer systems that use industry-standard 1/4″ quick-connect fittings.

Compact, Non-Swivel Design

The compact hexagonal body offers easy handling and wrench access for firm, torque-appropriate installation without
damaging seals or locking grooves. A non-swiveling design maintains alignment under pressure, reducing stress on
hoses and fittings and supporting longer component life in both stationary and mobile rigs.

Durability in Harsh Environments

Corrosion & Chemical Resistance

Because it is made of solid brass, the AL-QC1/4B maintains its performance in harsh conditions, resisting corrosion
from water, detergents, and outdoor exposure. It is well suited to professional cleaning systems, agricultural
spraying setups, industrial equipment maintenance, and any application where fittings see constant moisture and
chemical contact.

Heat Dissipation & Structural Integrity

The brass body also dissipates heat effectively, reducing thermal stress on sealing components and helping maintain
structural integrity during extended high-pressure use. Each coupler is manufactured to Annovi Reverberi’s strict
quality control standards and tested for dimensional accuracy, pressure endurance, and leak prevention.

Maintenance & Service Life

Simple Care Routine

Maintenance is straightforward:

• Inspect the internal O-ring periodically for wear, flattening, or damage.
• Clean coupling surfaces to remove dirt, mineral buildup, and chemical residue.
• Replace worn O-rings as needed to restore factory-tight sealing.

Brass requires no additional coating or treatment to resist corrosion, allowing the coupler to deliver years of
reliable service in tough working conditions.
