070654 - Miller Strain Relief Bushing .300 ID x .550 Mounting Hole

Genuine Miller 070654 Strain Relief Bushing

When you are troubleshooting a welder or performing routine maintenance, small details like strain relief bushings often get overlooked until a cable fails. The Miller 070654 is the specific replacement bushing required for various Miller power sources and wire feeders. It features a .300-inch Inner Diameter and is designed to snap into a .550-inch Mounting Hole. If your existing bushing is cracked, missing, or no longer gripping the cable securely, it is time to replace it to prevent more costly repairs down the line.

Strain relief bushings are the first line of defense for your machine's internal wiring. They prevent "pull-out" accidents where a trip over a cord could rip wires off the contactor or circuit board. Additionally, they provide insulation where the cable passes through the sheet metal case, preventing the metal from cutting into the cable jacket. This specific Miller part is manufactured to meet the original equipment specifications, ensuring it will hold up to the rigors of daily welding use. It is compatible with a range of Miller equipment; however, we always recommend verifying the part number in your machine's owner's manual or measuring your existing port dimensions before ordering.

Don't risk electrical safety or machine downtime with makeshift repairs. Using the correct bushing ensures that your equipment remains compliant with safety standards and operates reliably. The 070654 is sold individually, allowing you to purchase exactly what you need for your repair job. Whether you are refurbishing an older Millermatic or fixing a damaged control cable on a TIG runner, this OEM part provides the fit and finish you expect from Miller Electric.

Verification Steps

Before purchasing, please use calipers to measure the cable diameter and the panel hole diameter. This bushing is strictly for .300" ID and .550" mounting holes. If your measurements differ, you may require a different part number from the Miller catalog.
