AL-PLUG3/8B | 3/8 F Quick-Connect Plug, Brass

AL-PLUG3/8B

The AR AL-PLUG3/8B — 3/8″ Female Quick-Connect Plug | Brass Seal is an OEM-grade
brass fitting designed to make setup, tool changes, and teardown faster while preserving a tight,
leak-free seal in both professional and residential pressure washer systems. This
3/8″ female quick-connect plug snaps onto standard 3/8″ male couplers for
rapid swaps of hoses and tools, keeping flow steady and cleaning power consistent.

Construction & Materials

Built from solid, corrosion-resistant brass, the AL-PLUG3/8B combines long service
life with excellent machinability for crisp sealing lands and accurate dimensions. The plug is
precision-machined to Annovi Reverberi tolerances so it mates smoothly with standard 3/8″ male
quick-connect couplers used on hoses, spray guns, wands, foamers, and surface cleaners.

Brass construction naturally resists rust, scale, and dezincification in wet or outdoor environments
and sheds heat steadily during extended runs, helping protect adjacent seals and preserving connection
stability shift after shift.

AL-PLUG3/8B Quick-Connect Operation

The AL-PLUG3/8B delivers a confident, one-hand push-to-connect action that
clicks firmly into place, eliminating time-wasting thread starts, cross-thread risk,
and wrench work during frequent accessory changes:

• Snap on a foam cannon for pre-soak.
• Switch to a wide-fan tip for chemical dwell.
• Click in a rotary nozzle or surface cleaner for aggressive cleaning.

All of this can be done in seconds without tools, helping crews move quickly through multi-step
cleaning processes on mobile rigs or in shop bays.

Flow Path & System Performance

Internally, a smooth, unobstructed bore maintains full flow to the gun and nozzle, minimizing pressure
drop and preventing turbulence that can disturb spray patterns or reduce impact energy. By preserving a
clean hydraulic path from pump to nozzle, the plug supports:

• Stable operating pressure and gauge readings.
• Consistent spray geometry for efficient rinsing and soil removal.
• Reduced micro-leaks that waste water or cause nuisance cycling at the unloader.

The fixed, non-swivel configuration provides a rigid, vibration-resistant joint at the tool end or hose
tail, giving operators predictable hose behavior and a direct, dependable connection.

AL-PLUG3/8B Installation & Maintenance

Installation is straightforward:

• Verify the mating coupler O-ring is intact and lightly lubricated with a compatible grease.
• Push the plug into the coupler until the detent locks audibly.
• To remove, pull back the coupler sleeve and withdraw the plug in a controlled motion.

Because the plug’s geometry matches common industry profiles, it integrates easily with mixed fleets of
hoses and accessories, reducing adapter clutter and simplifying training for new technicians.

Maintenance is minimal—keep the sealing face and bore free of grit, rinse after chemical use, and
replace worn O-rings in the companion coupler as part of routine service. The compact hex allows easy
handling with gloved hands and simple wrenching when needed, while the smooth brass finish wipes clean
so wear checks remain quick and accurate.
