Corrugated Graphite Gasket, CS, SS, 1/2-60 Inch, 150/300 LB

Corrugated Graphite Gasket Manufacturer

The Corrugated Graphite Gasket Manufacturer specializes in producing high-performance sealing solutions engineered for demanding industrial environments. Our corrugated graphite gaskets feature a robust core made of carbon steel or stainless steel (304, 316, or other grades upon request), which is precision-formed with concentric corrugations to enhance compressibility and sealing effectiveness. This metal core is clad with multiple layers of flexible graphite, delivering exceptional resistance to high temperatures, chemical corrosion, and thermal cycling.

Available in a wide range of sizes—from 1/2 inch to 60 inches in diameter—these gaskets are suitable for Class 150 and Class 300 LB flange ratings, making them a versatile choice for pipelines, refineries, chemical plants, and power generation systems. Each gasket has a standard thickness of 2.38 mm, offering optimal balance between rigidity and flexibility to ensure reliable sealing even under fluctuating pressure and temperature conditions.

Key Features:

Core Material: Carbon steel or stainless steel (304, 316, etc.)

Facing Material: High-purity flexible graphite

Size Range: 1/2" to 60"

Pressure Ratings: Class 150 and 300 LB

Thickness: 2.38 mm (custom thicknesses available)

Temperature Resistance: Up to 450°C (in oxidizing environments) and up to 550°C (in non-oxidizing environments)

Applications: Oil & gas, petrochemical, chemical processing, steam systems, power plants, and general industrial use

These gaskets are engineered for longevity and performance in sealing joints where standard gaskets may fail. With excellent adaptability to flange surface irregularities and reduced leakage rates, they are a trusted solution for critical operations requiring low-emission, maintenance-free sealing technology.
