133739 - Miller 133739 Buna-N Rubber Flat Washer (Pack of 2)

Genuine Miller 133739 Rubber Flat Washer (2 Pack)

Maintain the integrity and performance of your Miller welding equipment with the genuine Miller 133739 Flat Washer. This essential replacement component is manufactured to exact factory specifications, ensuring a seamless fit and reliable operation within your machine's assembly. Sold as a package of two, this set allows for immediate replacement while providing a spare for future maintenance needs.

The washer is constructed from high-grade Buna-N (Nitrile) rubber. This material is specifically chosen for its outstanding mechanical properties and chemical resistance. In industrial welding environments, equipment is often exposed to various lubricants, oils, and fuels. Standard rubber washers may degrade, swell, or crack under these conditions, leading to leaks or mechanical looseness. Buna-N rubber offers superior resistance to petroleum-based oils and fuels, ensuring that the washer maintains its shape, flexibility, and sealing capability over a longer service life.

Dimensionally, the Miller 133739 features an Inner Diameter (ID) of 0.375 inches, an Outer Diameter (OD) of 0.625 inches, and a thickness of 0.062 inches. These precise measurements are critical for ensuring proper load distribution and sealing pressure. Whether used as a spacer to prevent metal-on-metal contact, a vibration dampener to reduce noise and wear, or a seal to prevent fluid ingress, this washer performs reliably. Using genuine OEM parts like this washer protects your investment by ensuring that every small component works in harmony with the rest of the system.

When servicing your welding power source or wire feeder, replacing worn or dried-out rubber components is a best practice that prevents larger issues down the line. Trust in the quality of Miller Electric parts to keep your operations running smoothly and efficiently.
