N-M5800C - Miller AccuLock MDX Nozzle 5/8" Flush (2-Pack)

Genuine Miller N-M5800C AccuLock MDX Nozzles (2-Pack)

Keep your welding operations running smoothly with this 2-pack of Miller AccuLock MDX Thread-On Nozzles. Specifically engineered for the MDX-250 series MIG guns, these nozzles (SKU: N-M5800C) combine industrial durability with intelligent design features that solve the most common issues faced by MIG welders. Whether you are fabricating in a shop or performing maintenance in the field, these nozzles deliver the consistency required for high-quality welds.

Secure Thread-On Connection

Loose nozzles can compromise shielding gas coverage and lead to porosity in your welds. The AccuLock MDX nozzle solves this with a coarse-thread design and a built-in steel retaining ring. This feature ensures the nozzle stays tight, even during extended welding periods where heat expansion typically causes parts to loosen. The secure fit also makes cleaning spatter easier, as the nozzle remains rigid while you ream or brush it out.

Enhanced Consumable Life

The N-M5800C is built from high-grade copper, optimized for thermal conductivity and durability. The 5/8-inch bore provides ample gas flow for standard MIG applications, while the flush tip alignment is ideal for short-circuit MIG welding, allowing for better maneuverability and visibility of the arc. By maintaining a concentric relationship with the contact tip and liner, this nozzle helps prevent premature wear caused by micro-arcing or wire drag.

System Compatibility

These nozzles are a key component of the AccuLock MDX system. They are designed to pair perfectly with AccuLock MDX contact tips and the D-M250 diffuser. Please note that these are not compatible with the smaller MDX-100 guns or legacy M-Series guns. Ensure your equipment utilizes the MDX-250 platform to experience the full benefits of this optimized wire-feeding technology.
