278751 - Miller Fiber Washer .281 ID x .625 OD (Pack of 4)

Genuine Miller 278751 Fiber Washer

The Miller 278751 Fiber Washer is a specialized component designed for precision applications within Miller welding equipment. When maintaining high-performance industrial machinery, the integrity of every small part is crucial to the overall operation. This specific washer is manufactured from high-quality fiber material, selected for its distinct mechanical and electrical properties. Unlike standard metal washers, fiber washers provide excellent electrical insulation and are often used to prevent galvanic corrosion or to isolate conductive components within a power source or wire feeder.

Engineered to exact factory tolerances, this washer features an Inner Diameter (ID) of 0.281 inches, an Outer Diameter (OD) of 0.625 inches, and a thickness of 0.065 inches. These precise dimensions ensure a snug fit that prevents rattling or loosening due to the high-vibration environments often found in industrial welding setups. The fiber material also offers a degree of compressibility, allowing it to form a tight seal between mating surfaces without marring or damaging the underlying components.

This product is sold in a package of four, providing maintenance teams and technicians with necessary spares. Small components like washers are easily lost during field repairs or shop overhauls; having a multi-pack ensures that your repair workflow is not interrupted by a missing part. Whether you are servicing a TIG torch assembly, a MIG wire drive system, or the internal connections of a power source, using genuine Miller parts guarantees compatibility and performance.

At Josef Gas, we are committed to supplying authentic OEM parts to maintain the reliability and safety of your welding operations. The Miller 278751 washer is a testament to that standard, offering the specific material composition required for safe equipment operation. Please verify your machine's parts manual to confirm this part number matches your specific model's requirements before installation.
