278664 - Miller 278664 Wire Feed Conduit Assembly, 130-Inch

Keep Your Wire Feeding Smooth and Reliable

Every welder knows that a consistent arc starts with consistent wire feeding. If your wire is dragging, stuttering, or jamming, the culprit is often a worn-out or dirty conduit. The Miller 278664 Conduit Assembly is the direct replacement you need to get your machine back to feeding like new. Designed specifically for Miller equipment, this 130-inch long conduit provides a clean, protected highway for your welding wire, ensuring it gets from the spool to the feeder without a hitch.

Why does the conduit matter? Think of it as the veins of your welding system. If the path is clogged or restricted, the flow suffers. This assembly features a large 0.550-inch inner diameter, which is spacious enough to handle various wire sizes with minimal friction. This reduction in drag means your drive rolls don't have to work as hard, extending the life of your motor and reducing the chance of wire slippage. The tough 0.750-inch outer shell protects the liner from getting crushed or kinked around the shop, which is a common cause of sudden feeding failures.

Installation is straightforward because this isn't just a bulk hose—it's a finished assembly with the necessary connectors already attached. You won't have to waste time fumbling with hose clamps or trying to adapt a generic tube to your specific machine. Just verify the part number with your manual, swap it out, and get back to welding. It is an ideal solution for maintenance teams looking to perform preventative upkeep on their fleet of wire feeders.

Don't let a cheap or worn-out guide tube ruin your welds. Erratic feeding leads to burn-backs, uneven beads, and frustration. By replacing your old conduit with this genuine Miller 278664 assembly, you eliminate one of the most common variables in troubleshooting wire feed issues. Keep a spare on the shelf to ensure that when a line goes down, you have the right part to fix it immediately. Invest in genuine Miller parts to keep your shop running at peak efficiency.
