118267 - Miller Roughneck Contact Tip Adapter

Keep Your Roughneck Gun Running Smoothly

If you are running a Miller Roughneck MIG gun, you know it's built to take a beating. But even the toughest guns need maintenance, and the contact tube adapter is often the unsung hero of your setup. The Miller 118267 Adapter is the piece that holds your contact tip in place, screwing directly into the neck of your gun. It’s the bridge that carries the welding power to your wire, so keeping it in good shape is non-negotiable for a smooth, consistent arc.

Over time, heat and constant thread changes can wear out your old adapter. If you've ever stripped the threads while changing a tip in a hurry, or if you're noticing your tips are overheating faster than usual, it might be time to swap out the adapter. A worn adapter can cause a loose connection, which leads to a hot gun, erratic arc starts, and frustrating wire burn-backs. By installing a fresh, genuine Miller 118267, you ensure that your contact tip sits tight and center, giving you the electrical contact you need for those perfect beads.

This part is designed specifically for the Roughneck C-Series (like the C-3015 or C-4015). Because it is an OEM part, you don't have to worry about cross-threading or fighting to get it to fit. It installs in seconds—just unscrew the old one and thread this one on. It’s a smart part to keep in your toolbox or consumable kit. When you are in the middle of a project, the last thing you want is a $10 part shutting down your $5,000 machine. Stick with genuine Miller parts to keep your equipment running at factory specs and minimize downtime in the shop.
