This replacement assembly is designed specifically for the popular M-100 series MIG guns, commonly found on Millermatic machines used in garages, body shops, and fabrication facilities. The 246373 features the precise geometry required to align your liner with the contact tip, ensuring the wire travels smoothly without drag or kinking. It also provides a secure seating surface for your gas diffuser and nozzle, preventing gas leaks that could compromise your weld shielding.

Installation is straightforward, allowing you to swap out a damaged neck and resume work quickly. Simply disassemble the handle of your M-100 gun, remove the old tube, and secure the new Miller 246373 in place. Investing in genuine Miller parts means you don't have to worry about fitment issues or premature failure.
