169727 - Miller M-25/M-40 Slip Nozzle, 5/8" Orifice, 1/8" Stickout

Genuine Miller Performance for Your M-25 MIG Gun

Keep your Millermatic welder running at peak performance with the genuine Miller 169727 MIG Nozzle. If you are welding with the industry-standard M-25 or M-40 MIG guns—commonly found on machines like the Millermatic 200, 210, 250, and 252—this is the authentic replacement part you need to ensure consistent, high-quality welds. Using genuine Miller consumables is the best way to guarantee that your equipment operates exactly as the engineers intended, providing the reliability you expect from the brand.

The 169727 nozzle features a 5/8-inch orifice, which is the "go-to" size for most standard welding applications. It provides a broad, stable umbrella of shielding gas that effectively protects your molten weld pool from porosity-causing oxygen and nitrogen. Whether you are fabricating mild steel brackets or performing repairs on heavy equipment, this nozzle delivers the coverage required for a clean, sound bead. The 1/8-inch stickout is a favorite feature among many professional welders because it keeps the contact tip slightly recessed. This recess helps prevent the tip from shorting out against the workpiece in tight corners and reduces the likelihood of spatter bridging the gap between the tip and the nozzle.

One of the biggest advantages of this nozzle is its slip-on design. Unlike threaded nozzles that can seize up with heat and spatter, the Miller slip-type nozzle pulls off easily. This makes your routine maintenance—like cleaning out spatter buildup or changing a contact tip—fast and frustration-free. Made from durable copper, it resists heat buildup and stands up to the rigors of daily shop use. Don't compromise your weld quality with ill-fitting generic parts; stick with the Miller 169727 for a perfect fit and superior arc visibility.
