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

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

The AR AL-QC1/4MB — 1/4 in Quick-Connect Coupler, 1/4 F x 1/4 M, Brass is a precision-engineered
fitting designed by Annovi Reverberi to deliver secure, leak-free, and efficient connections in high-pressure
cleaning systems. With its 1/4-inch female x 1/4-inch male quick-connect configuration, this coupler
lets operators connect hoses, spray guns, and accessories quickly and safely without tools, keeping setup and
accessory changes fast in both professional and residential pressure washer applications.

Construction & Materials

Solid Brass Body

• Corrosion-resistant brass construction resists rust, oxidation, and chemical attack in wet, detergent-rich environments.
• High mechanical strength maintains dimensional stability and sealing integrity through thousands of pressure cycles.
• Precision-machined threads and sealing lands promote perfect alignment and consistent engagement with mated components.
• Brass body helps dissipate heat, protecting internal seals during extended high-pressure operation.

This robust build provides long-term reliability for mobile rigs, shop bays, and outdoor systems that see daily
use and frequent reconnection.

Quick-Connect Operation

Fast, Tool-Free Coupling

• Standard 1/4-inch female quick-connect socket accepts compatible male plugs from most major pressure-washer brands.
• One-handed connect: push the plug into the coupler until it locks with a positive click for an instant, leak-proof joint.
• Quick release by pulling back the sleeve—no wrenches or manual threading required.
• Locking mechanism is engineered to resist vibration and pressure spikes, keeping the connection secure under load.

The AL-QC1/4MB is ideal anywhere operators routinely switch between foam cannons, turbo nozzles, surface
cleaners, extension wands, and other accessories throughout the workday.

Flow & Sealing Performance

Smooth Bore, Stable Pressure

• Smooth internal bore minimizes restriction and turbulence, helping maintain full pump flow and stable system pressure.
• Polished sealing surfaces support consistent O-ring contact for a tight, bubble-free seal.
• Heavy-duty internal O-ring resists deformation under continuous high-pressure use.
• Designed to reduce pressure loss and weeping, improving spray consistency and cleanliness around the work area.

Together, these features create a calm hydraulic path that supports efficient cleaning, predictable unloader
behavior, and reliable downstream chemical draw where injectors are used.

Configuration & Integration

1/4 F x 1/4 M Versatility

• 1/4-inch female quick-connect x 1/4-inch male thread makes the coupler a useful link between mixed connection styles.
• Works as a transition piece when joining hoses, guns, or accessories that alternate between threaded and QC interfaces.
• Compact hexagonal body provides solid wrench flats for tightening while remaining easy to grip by hand.
• Fixed, non-swivel design preserves alignment and prevents loosening under vibration in mobile or trailer-mounted systems.

The AL-QC1/4MB drops into existing rigs without re-plumbing, helping standardize connection points across fleets
and simplifying training for new operators.

Reliability, Testing & Maintenance

Factory-Verified Performance

• Manufactured to tight dimensional tolerances for repeatable fit and sealing performance.
• Each coupler is pressure-tested for leak prevention, flow efficiency, and durability before shipment.
• Brass body withstands repeated exposure to detergents, hot water, and outdoor conditions without flaking or rust formation.

Simple Care

• Periodically rinse and wipe coupling surfaces to remove grit or chemical residue.
• Inspect and replace the internal O-ring if it shows flattening, nicks, or chemical damage.
• A light application of non-reactive lubricant on the O-ring can improve engagement feel and extend service life.

With basic care, the AL-QC1/4MB continues to provide reliable, leak-free performance across years of regular
use in demanding environments.
