269049 - Miller Nylon Shoulder Washer .375 ID x .750 OD

Precision Miller Replacement Hardware

The Miller 269049 Washer is a specialized nylon shoulder washer designed to meet the rigorous specifications of Miller Electric welding equipment. In the complex assembly of industrial power sources and wire feeders, even the smallest hardware components play a critical role in machine reliability and safety. This washer is not merely a spacer; it is an engineered component featuring specific dimensions—0.375-inch Inner Diameter (ID) and 0.750-inch Outer Diameter (OD)—to ensure exact fitment within the designated assembly.

Material and Design Excellence

Manufactured from high-grade nylon, this shoulder washer offers essential properties for welding environments. Nylon is chosen for its excellent electrical insulating capabilities, which are vital when separating conductive metal components within the machine's chassis or electrical sub-assemblies. The "shoulder" or stepped design allows the washer to seat into a mounting hole, centering the bolt or shaft while simultaneously preventing metal-to-metal contact that could lead to electrical shorts or ground faults. Additionally, the nylon material provides a degree of vibration damping, helping to secure connections against the high-frequency vibrations often generated during heavy-duty welding operations.

Exact Specifications for Maintenance

Maintenance professionals understand that substituting generic hardware in precision equipment can lead to long-term issues. The Miller 269049 features a shoulder diameter of 0.500 inches and a shoulder length of 0.188 inches, with a flange thickness of 0.063 inches. These precise tolerances ensure that the washer performs its intended function without introducing play or misalignment. Whether used in the wire drive assembly, the mounting of electrical components, or structural isolation, this OEM part guarantees that the machine operates as originally engineered.

Why Choose Genuine OEM Parts?

Using genuine Miller parts like the 269049 washer ensures compatibility and longevity. Generic washers often lack the specific thermal resistance or dimensional accuracy required, leading to premature wear or failure. By selecting the authentic Miller replacement, you maintain the integrity of your equipment, ensuring that warranty standards are met and that the machine continues to deliver the performance expected from a top-tier welding brand.
