What are Copper Flat Gaskets?

Copper Flat Gaskets are flat metallic sealing components manufactured from high-purity copper. They are installed between two mating flange surfaces to prevent leakage of liquids, gases or steam under high-pressure and high-temperature operating conditions.

Copper is widely recognized for its exceptional thermal conductivity, corrosion resistance and excellent malleability. These properties enable Copper Flat Gaskets to deform slightly under compressive load, filling surface irregularities and creating an effective leak-tight seal without compromising structural integrity.

Copper Flat Gaskets are commonly used in boilers, heat exchangers, hydraulic systems, compressors, diesel engines, pumps, valves, chemical processing equipment, pressure vessels and power generation facilities where reliable sealing performance is critical.
