266920 - Miller Potentiometer Mounting Nut with Neoprene Seal .375-32

Genuine Miller Replacement Hardware

Maintain the integrity and reliability of your Miller welding equipment with the Miller 266920 Nut. This is a genuine OEM replacement part designed specifically to fit Miller machine specifications. Often overlooked, the hardware on the front panel of your welder plays a crucial role in protecting the sensitive internal electronics from the harsh industrial environment.

This specific nut is engineered with a .375-32 thread pitch and a 0.50-inch hex head, making it a standard fit for many control potentiometers and switches used in Miller power sources. What sets this component apart is the integrated black neoprene pot seal. This built-in seal compresses against the machine's faceplate during installation, creating a barrier against dust, metal shavings, and moisture that could otherwise bypass the shaft and damage the component behind the panel.

At Josef Gas, we understand that downtime is costly. Whether you are refurbishing an older machine or replacing a damaged control pot, using the correct mounting hardware is essential for a professional repair. This nut ensures your controls remain secure and your machine retains its protective rating.
