💡 Why choose copper washers over steel for high temperature applications?

- These soft metals conform tightly to bolt threads stopping seepage instantly.
- Thermal expansion matches well so leaks do not form after engine heating cycles.
- Reusable seal property saves money compared to replace aluminum or rubber parts.
