Metal Copper Gasket

Он metal copper gasket is a high-performance sealing component manufactured from high-purity purple copper (T2 or TU1 grade). Designed for demanding industrial environments, it is widely used in high-temperature and high-pressure pipeline systems, including flanges, valves, pumps, and pressure vessels.

Thanks to the excellent plasticity and thermal conductivity of pure copper, the gasket can effectively fill microscopic irregularities on flange surfaces, ensuring reliable static sealing even under severe operating conditions. With a copper purity of ≥99.9%, these gaskets deliver superior mechanical stability, corrosion resistance, and long service life.

Metal copper gaskets are commonly used in power generation, petrochemical processing, shipbuilding, aerospace, and heavy industrial equipment, where reliable sealing performance and thermal stability are essential.

Key Product Features

Excellent Sealing Adaptability

Copper is naturally soft and highly ductile, allowing the gasket to conform to flange surface irregularities and create an immediate tight seal.

Wide Temperature Resistance

• Operating temperature: -196°C to +250°C

• Short-term temperature tolerance: up to 350°C

This wide temperature range ensures consistent sealing performance in extreme thermal environments.

Strong Compression and Elastic Recovery

Under high bolt preload, the gasket deforms uniformly while maintaining good resilience, helping compensate for pressure fluctuations and thermal expansion.

Reliable and Reusable

Copper gaskets exhibit excellent corrosion resistance, anti-aging properties, and radiation resistance, allowing reuse in many maintenance cycles.

High Thermal and Electrical Conductivity

The copper structure enables rapid heat transfer and can also serve as an electrical grounding or conductive interface in certain flange systems.
