170468 - Miller 170468 Power Pin O-Ring for M-Series MIG Guns

Genuine Miller Replacement O-Ring for M-Series Guns

Keep your Miller MIG equipment running at peak performance with the Miller 170468 O-Ring. This small but critical component is designed specifically for Miller M-Series MIG guns, including the popular M-25, M-10, M-15, and M-40 models. At Josef Gas, we understand that even the smallest part can halt production or affect weld quality, which is why we stock genuine Miller replacement parts to get you back to welding quickly.

The 170468 O-Ring sits on the power pin of your MIG gun—the end that plugs directly into the wire feeder or welding machine. Its primary function is to create an airtight seal for the shielding gas channel. Over time, O-rings can dry out, crack, or become compressed, leading to subtle gas leaks. These leaks not only waste expensive shielding gas but can also introduce atmospheric air into your weld zone, causing defects. By replacing this O-ring during routine maintenance, you ensure a tight connection and reliable gas delivery.

Trust in genuine Miller parts for the best fit and longevity. Generic seals may not have the exact dimensions or material composition required to withstand the heat and pressure of industrial welding environments. Whether you are repairing an older M-25 gun or performing maintenance on a fleet of M-10 torches, this O-ring is the factory-correct solution.
