Graphite Gasket

Pressure Seal Ring Gasket, Flexible Graphite, Class 4500

This pressure seal ring gasket, manufactured in China with precision and high-performance materials, is engineered to deliver exceptional sealing reliability in extreme high-pressure environments. Constructed from premium flexible graphite, the gasket provides outstanding compressibility, chemical resistance, and thermal stability, ensuring consistent sealing integrity even under severe operating conditions.

Rated for pressures up to 77.6 MPaG (Class 4500 LB), this pressure seal ring is specifically designed for demanding applications such as valve bonnets, high-pressure vessel lids, and other critical pressure-containing assemblies. Its robust structure allows it to maintain a secure, leak-free seal during pressure cycling, high-temperature exposure, and long-term service.

With inherently low emission characteristics, the flexible graphite material minimizes fugitive leakage, supporting environmental compliance and enhancing operational safety. Its durability and resistance to aging make it an ideal solution for industries requiring continuous, reliable high-pressure containment—such as power generation, petrochemical processing, oil and gas, and high-temperature steam systems.

Combining superior material performance with precision manufacturing, this pressure seal ring gasket delivers the long-lasting, high-integrity sealing essential for critical applications operating under Class 4500 LB pressure ratings.You can explore a comprehensive list of global suppliers on the Valve Manufacturers Directory
