Miller 047235 Washer, Seal Oil Copper (.879 ID x 1.059 OD)

Keep your Miller welding machine running smoothly with the Miller 047235 Copper Seal Oil Washer. In the world of welding and fabrication, equipment reliability is paramount. A simple oil leak can lead to messy workspaces, safety hazards, and eventually, catastrophic equipment failure if fluid levels drop too low. This copper washer is designed specifically to act as a crush seal in oil systems, providing a secure barrier against fluid escape. Copper is the industry standard for these applications because it is soft enough to compress under torque, forming a perfect gasket-like seal between metal surfaces, yet durable enough to handle high temperatures and pressures.

This specific washer features an inner diameter of 0.879 inches and an outer diameter of 1.059 inches, making it a specialized part for specific Miller applications. The thickness of 0.056 inches is calculated to provide the optimal amount of compression. Unlike rubber or fiber washers that may degrade quickly under heat or chemical exposure, this copper washer offers long-term durability. It is often used in conjunction with drain plugs, banjo bolts, or other hydraulic fittings where a reliable static seal is required. Replacing these washers during service intervals is a best practice that prevents future headaches; reusing an old, already-crushed copper washer often results in leaks.
