This copper washer, with an inner diameter of 21/64 inch and an outer diameter of 9/16 inch, serves as an effective sealing element in fluid systems. Its 1/16-inch thickness provides a flexible yet firm barrier to prevent leaks at connections under high pressure. Copper’s excellent thermal and electrical conductivity, combined with its malleability, makes it ideal for sealing applications where heat dissipation and corrosion resistance are critical. It accommodates slight surface irregularities to create a tight seal, preventing fluid loss and contamination. This washer is particularly important in high-pressure fuel and coolant systems, where maintaining a leak-proof connection is essential for engine performance and safety.
