169725B - Miller 169725 Replacement Slip Nozzle, 5/8" Orifice, 1/8" Recess

Reliable Gas Coverage for M-Series Guns

Keep your MIG welding operations running smoothly with the Miller 169725 style slip nozzle. Designed as a direct replacement for the standard nozzle found on many Millermatic welders, this component features a 5/8-inch bore that provides excellent gas coverage for short-circuit and spray transfer modes. Whether you are welding mild steel, stainless, or aluminum, having a fresh nozzle is critical for preventing weld defects caused by turbulent or insufficient gas flow.

The slip-on design is a favorite among professional welders for its convenience. Unlike threaded nozzles that can become cross-threaded or fused to the diffuser, this nozzle slides over the nozzle spring, staying secure during use but pulling off easily for cleaning or replacement. The 1/8-inch recess positions the contact tip slightly back inside the nozzle, offering a layer of protection against spatter bridging and accidental contact with the base metal.

This nozzle is compatible with a broad ecosystem of Miller equipment, fitting the M-25 gun supplied with the Millermatic 250, 251, and 252, as well as the M-40 and smaller M-Series guns. Regular inspection and replacement of your nozzle will help maintain arc stability and reduce downtime associated with spatter removal. This bulk-packaged version ensures you have the inventory needed to keep your production line moving.
