AL-QC1/4MBSS | 1/4 F x 1/4 M Quick-Connect Coupler, Stainless

AL-QC1/4MBSS

The AR AL-QC1/4MBSS – 1/4″ Quick-Connect Coupler (1/4″ F x 1/4″ M) is a
professional-grade stainless-steel fitting from Annovi Reverberi, engineered to deliver fast, secure, and
corrosion-resistant connections for high-pressure washer systems. Featuring a 1/4″ female x 1/4″
male quick-connect configuration, this coupler enables seamless attachment between hoses, spray guns, and
accessories without tools, making it ideal for users who demand efficiency, reliability, and durability in demanding
industrial, marine, and commercial cleaning environments.

Construction & Materials

All-Stainless-Steel Body

Constructed entirely from precision-machined stainless steel, the AL-QC1/4MBSS is built to endure
extreme pressure, vibration, and chemical exposure without corroding or losing integrity. Stainless steel’s inherent
strength and resistance to oxidation make it the preferred material where longevity and safety are paramount. Unlike
plated or brass alternatives, stainless steel maintains its finish and mechanical properties over years of use, even
when exposed to detergents, saltwater, or harsh outdoor conditions.

Precision Machining

Each fitting is machined to tight tolerances to guarantee consistent sealing, smooth coupling engagement, and
vibration-resistant performance at high operating pressures. Precision-ground sealing surfaces provide perfect
O-ring contact, helping the coupler maintain a reliable, leak-free interface through thousands of connect/disconnect
cycles.

Quick-Connect Operation

Tool-Free, One-Handed Use

The quick-connect mechanism is designed for effortless one-handed operation:

• To connect, push the compatible male plug into the coupler until it locks with a firm, audible click.
• The locking action creates an immediate, watertight seal capable of withstanding high pressure and vibration.
• To disconnect, pull back the coupler sleeve to release the plug and switch attachments in seconds.

This design eliminates the need for threading, reducing setup time and preventing thread wear from repeated
tightening and removal. The precision-fit locking mechanism ensures a tight, leak-free connection that stays put in
demanding, high-cycle systems.

Performance & Flow Characteristics

Optimized Internal Flow Path

Internally, the AL-QC1/4MBSS is optimized for efficiency and pressure stability. Its smooth bore minimizes flow
restriction, maintaining consistent water flow and pressure from pump to nozzle. The heavy-duty stainless housing
resists distortion under pressure, preserving alignment and seal contact so spray patterns remain stable and
predictable.

Corrosion-Resistant Sealing Components

Corrosion-resistant internal components and precision sealing surfaces keep the O-ring seated properly, providing
long-term leak protection even in high-moisture or chemical-intensive environments. Stainless steel’s hardness helps
the coupler retain exact geometry over time, preventing galling and deformation that could compromise sealing.

Configuration & Integration

1/4″ F x 1/4″ M Versatility

The 1/4″ female x 1/4″ male quick-connect layout offers flexible integration in mixed
systems:

• Use the female side as a connection point for standard 1/4″ quick-connect plugs from hoses, wands, or tools.
• Use the male side to interface with 1/4″ quick-connect couplers elsewhere in the system.

This configuration acts as a reliable adapter between components while maintaining the system’s full pressure
capacity.

AL-QC1/4MBSS Compact, Non-Swivel Body

The compact hexagonal body allows easy tightening by hand or with a wrench and keeps assemblies short and balanced.
A fixed, non-swivel design maintains long-term stability at the joint, preventing leaks caused by twisting or
vibration. The polished stainless exterior resists buildup and is easy to wipe clean after use.

Durability in Harsh Environments

Extreme Corrosion Resistance

The AL-QC1/4MBSS offers exceptional corrosion resistance, making it a top choice for marine applications,
chemical cleaning systems, and industrial wash bays where lesser materials may degrade. Stainless steel
resists rust, pitting, and scaling even under constant exposure to water, detergents, and outdoor conditions.

High-Pressure & Temperature Capability

Engineered for continuous high-pressure use in both hot- and cold-water systems, the coupler maintains tight seals
and consistent pressure across variable working conditions. Stainless steel’s strength and thermal stability protect
against fatigue and deformation over long duty cycles.

Quality Assurance & Maintenance

Factory Testing

Each AL-QC1/4MBSS coupler undergoes Annovi Reverberi’s stringent quality control testing for sealing performance,
dimensional accuracy, and pressure endurance. Every unit is verified before shipment to ensure safe, leak-free
operation in demanding environments.

Simple Service Routine

Maintenance is minimal:

• Periodically clean coupling surfaces to remove dirt, film, or mineral deposits.
• Inspect the internal O-ring for wear, cuts, or flattening and replace as needed.
• Keep the mating plug and O-ring clean and lightly lubricated with a suitable non-reactive grease.

Because stainless steel resists rust and scaling, the coupler requires no special coatings or protective treatments to
preserve performance.
