AL458-B-15 | M22 M x 14 to M22 F x 15 Fixed QC Coupling Brass

AL458-B-15

AL458-B-15 — Fixed QC Coupling M22M×14 to M22F×15 is a purpose-built quick-coupling from
Annovi Reverberi that bridges an M22 male × 1.4 mm thread to an
M22 female × 1.5 mm thread. It gives technicians a simple, repeatable way to mate components
that use different M22 formats while preserving a clean, leak-resistant path for water and detergent in
pressure-washer systems. By consolidating the conversion into a single compact fitting, the AL458-B-15 supports
quick reconfigurations, stable seals, and consistent performance on skids, carts, and wall-mount bays.

Why this adapter is important in mixed M22 systems

One-step bridge between M22M×14 and M22F×15 threads

Many hoses, guns, wands, and manifolds arrive with different M22 thread pitches. Instead of re-plumbing lines or
stacking multiple adapters, the AL458-B-15 provides a direct transition from an M22M×14 port to an M22F×15
connection in one part. This keeps assemblies short and tidy, reduces potential leak paths, and simplifies
decisions at the bench—“use AL458-B-15 where 14 meets 15” becomes the standard rule across the shop.

Fixed body for stable, leak-tight joints

The coupling’s fixed (non-swivel) design holds alignment under vibration and start–stop cycling, helping the seal
stay seated and discouraging the micro-movement that can cause weeping or thread wear over time. With both ends
tuned to the correct engagement depth and shoulder contact for their respective M22 formats, the adapter delivers
a reliable joint even after repeated assembly and disassembly during accessory changes or service.

Hydraulic behavior & on-gun performance

Low-restriction path for calmer hydraulics

Inside, the AL458-B-15 maintains a direct, low-turbulence flow path so the pressure transition occurs at the
threads, not in a maze of sudden diameter changes. In practice, that helps keep the unloader calmer and reduces
pressure saw-toothing at the trigger, which shows up as smoother spray patterns and a more predictable feel at
the gun. When downstream injectors are engaged, the stable inlet conditions also support more consistent chemical
draw and fewer nuisance adjustments.

Balanced size that fits tight layouts

A compact profile allows the adapter to sit cleanly on carts, skids, and inside equipment shrouds without
crowding filters, unloaders, gauges, or hose reels. The clean exterior wipes down quickly after splash, keeping
inspection points visible at shutdown and making it easy to spot any developing issues during routine checks.

Installation, service & troubleshooting

Familiar thread-in installation with reliable sealing

Installing the AL458-B-15 mirrors standard M22 practice: verify both mating threads are clean and undamaged, start
by hand to confirm proper pitch and alignment, then snug to the recommended tightness to compress the sealing
faces. Overtightening is unnecessary and can distort seats; a square, moderate draw yields a durable seal. Once
the system is pressurized, a quick visual check at the joint confirms leak-free performance. If a drip appears,
depressurize, re-seat, and ensure that the threads and sealing surfaces are free of debris before returning to
service.

Simple maintenance and a clear diagnostic checkpoint

Routine care is limited to rinsing, a brief visual inspection, and occasional verification that both ends remain
snug. Because the adapter represents a clear A/B connection between two thread standards, it also serves as a
convenient diagnostic checkpoint—if misting, intermittent pressure loss, or stubborn engagement appears, removing
and inspecting the AL458-B-15 helps isolate whether the issue originates at this interface or elsewhere in the
circuit.

Fleet standardization & inventory benefits

Unifying mixed-thread equipment with one part number

For service teams supporting multiple brands of hoses and tools, the AL458-B-15 reduces the need to stock
duplicates in both M22 formats. Standardize hoses or manifolds on one thread pitch, then use this adapter at the
gun or accessory to bridge to the other. The clear specification—M22M×14 to M22F×15—is easy to
label, reorder, and teach, shortening training time and reducing assembly errors in shops, rental fleets, and
mobile service trucks.

Consistent connection routine for crews and renters

Across residential, commercial, and light industrial environments, standardizing key junctions on the
AL458-B-15 creates a consistent connection routine: operators learn one adapter for all mixed-M22 situations,
rather than sorting through a handful of similar-looking pieces. That consistency helps keep jobs moving, reduces
frustration at setup, and supports safer operation by minimizing improvised fittings.

Key Features

• Fixed QC coupling converting M22 male × 1.4 mm thread to
  M22 female × 1.5 mm thread.
• Compact, non-swivel body maintains alignment and a stable, leak-resistant seal.
• Low-restriction hydraulic path supports steady pressure and reduced unloader chatter.
• Designed for repeated assembly and disassembly with consistent sealing depth and shoulder contact.
• Easy, thread-in installation using standard tools and familiar M22 procedures.
• Ideal for standardizing mixed-thread hoses, guns, wands, and accessories across fleets and rental units.

Typical applications

• Adapting new spray guns or lances with one M22 standard to existing hoses built on the other.
• Converting rental and fleet equipment to a common thread standard for faster turnaround.
• Building modular wash stations that swap tools quickly between foam, rinse, and specialty accessories.
• Supporting mobile rigs and wall-mount bays where multiple brands of hoses and guns must interconnect.

Bottom line

The AR AL458-B-15 — Fixed QC Coupling M22M×14 to M22F×15 is a compact, dependable bridge
between two common M22 thread formats. By turning mixed-thread connections into a single, repeatable adapter
point, it keeps water moving through the nozzle with stable pressure, fewer leak paths, and less downtime—so
technicians can focus on cleaning, not fittings.
