The Pressure Seal Ring Gasket, manufactured in China, is a premium sealing solution designed for extreme pressure applications where safety, durability, and performance are paramount. Made from high-purity flexible graphite, this gasket provides exceptional sealing integrity under severe temperature and pressure fluctuations.

Engineered for operating pressures up to 77.6 MPaG (Class 4500 LB), it is widely used in pressure seal bonnets of high-pressure valves, steam systems, and vessel lids in power generation, oil refining, and chemical processing industries. The flexible graphite material allows for excellent compressibility and recovery, ensuring a tight, uniform seal even under high-stress conditions.

Key Features and Advantages:

• High-pressure performance: Rated for Class 4500 LB, ensuring reliable sealing in the most demanding environments.

• Superior sealing efficiency: Flexible graphite provides tight sealing with low torque requirements and minimal relaxation over time.

• Low-emission design: Meets stringent environmental standards by minimizing fugitive emissions and leakage.

• Thermal and chemical resistance: Performs effectively in both high-temperature and corrosive service conditions.

• Extended service life: Resistant to aging, oxidation, and extrusion, ensuring long-term stability and reduced maintenance.

With its robust design and proven performance, the pressure seal ring gasket is the preferred choice for critical containment applications that demand absolute reliability, safety, and environmental compliance.
