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

Miller 169725B Slip Nozzle Overview

The Miller 169725B is a standard replacement slip-on nozzle designed for use with Miller M-Series and Hobart H-Series MIG welding guns. Featuring a 0.625-inch (5/8") orifice, this nozzle is the industry standard for general-purpose fabrication, offering a balanced shielding gas envelope that suits a wide range of wire diameters and amperages. The unit is engineered with a 0.125-inch (1/8") tip recess, which helps protect the contact tip from excessive spatter and reduces the risk of arcing against the workpiece during tight maneuvering.

Constructed from high-quality copper alloy, the 169725B is built to withstand the high heat of industrial welding environments. Its slip-on interface works in conjunction with a nozzle adapter or spring (such as the 169716), allowing welders to remove and clean the nozzle quickly without the hassle of seized threads. This specific SKU represents the bulk packaging option, making it an economical choice for high-volume shops that require frequent consumable replacements.

This nozzle is directly compatible with popular MIG guns found on Millermatic machines, including the M-10, M-15, M-25, and M-40 guns. It is an essential consumable for maintaining weld quality, as a clean and properly sized nozzle ensures the shielding gas is directed effectively over the weld pool, preventing porosity and oxidation.
