Is the Copper Flat Gasket – Type UM suitable for threaded connections exposed to temperatures up to +250°C?

Yes. The Copper Flat Gasket – Type UM is suitable for threaded connections exposed to temperatures up to +250°C. Made from high-quality copper, it offers excellent thermal conductivity, durability, and resistance to wear, pressure, and mechanical stress. Its precise flat design ensures a secure, leak-minimizing fit for demanding applications in machine construction, automotive systems, and industrial assemblies. Easy to install and versatile, it withstands high thermal loads while maintaining long-term sealing performance.

Can the Copper Flat Gasket – Type UM be reused after removal without compromising its sealing performance?

Can the Copper Flat Gasket – Type UM be reused after removal without compromising its sealing performance? Reusing the Copper Flat Gasket – Type UM after removal is not recommended if optimal sealing performance is required. Although manufactured from high-quality copper with excellent durability, resistance to wear, and good thermal conductivity up to +250°C, the gasket’s flat design relies on a pristine, undistorted surface to form a reliable seal in threaded connections. Removal and reinstallation can cause deformation, surface marring, or work-hardening of the copper, which may compromise its ability to conform to mating surfaces and maintain leak-tightness under thermal, pressure, and mechanical stress. For critical applications—machine construction, automotive systems, or high-temperature industrial assemblies—best practice is to replace the gasket with a new Copper Flat Gasket – Type UM after disassembly to ensure long-term reliability, reduced maintenance, and continued pressure/temperature performance. Reuse may be acceptable only for non-critical, low-pressure conditions after careful inspection showing no visible damage, but this carries increased risk.
