184101 - Miller Nylon Shoulder Washer .140 ID (Pack of 2)

Keep Your Miller Welder Running with Genuine Parts

There is nothing more frustrating than having a high-performance welding machine down because of a tiny, broken plastic part. The Miller 184101 Nylon Shoulder Washer is one of those small but mighty components that keeps your rig running smoothly. Whether you are performing routine maintenance, replacing a worn-out switch, or rebuilding a sub-assembly, using the correct washer is essential. These washers are often used to isolate electrical components from the metal frame of the welder, preventing dangerous shorts and ensuring your machine operates safely.

Why choose genuine Miller parts? It comes down to fit and peace of mind. Trying to find a generic washer at the hardware store that matches these specific stepped dimensions (.140 ID with a .250/.340 OD step) is a headache you don't need. A generic washer might not fit the hole correctly or might be made of a material that can't handle the heat and environment inside a welder. This genuine Miller 184101 washer drops right in, fitting perfectly every time because it was made for your machine. It restores the factory specifications, ensuring that knobs turn smoothly, boards stay isolated, and screws stay tight.

This product comes as a convenient 2-pack. We know that when you take a machine apart, small washers have a habit of rolling under the workbench or disappearing entirely. Having two in the pack means you have what you need to finish the repair right now, or you have a spare to throw in your parts bin for next time. Don't risk your equipment's reliability on makeshift fixes. Stick with the OEM parts that were designed to protect your investment.

Installation is straightforward—simply replace the cracked, worn, or missing washer with the new one during your repair process. These nylon washers are tough, resistant to oil and grease, and provide the electrical insulation your machine needs. Check your manual or parts diagram to confirm this is the right part for your specific model, and get your Miller welder back to peak performance.
