High-Temp Resistant Graphite Gasketing for Deep-Cooling & High-Vacuum Environments | Custom Thickness Options

Engineered to excel in extreme operational conditions, our high-temperature resistant graphite gasketing solutions redefine reliability for deep-cooling and high-vacuum applications. Tailored with precision to meet the most demanding industrial requirements, these gaskets combine advanced materials science with customizable thickness options to deliver unmatched performance.

Key Technical Specifications

Constructed with dual-layer pure flexible graphite sheets sandwiching a 0.2-0.25mm perforated metal insert, these gaskets offer a robust structural foundation. The metal core, available in carbon steel (tinplate), SS201, 304, or 316 alloys, provides enhanced tensile strength and dimensional stability. Choose from graphite carbon content grades of 95%, 97%, 98%, or 99% to align with your specific operational demands.

Exceptional Performance Attributes

Extreme Environment Resistance: Engineered to withstand thermal cycling in steam systems and exhaust applications, these gaskets maintain integrity across wide temperature gradients. Their high-pressure tolerance makes them ideal for critical power generation equipment subjected to constant stress.
Superior Sealing Mechanism: The unique laminate structure ensures zero delamination risk, delivering consistent sealing performance even in fluctuating conditions. The material’s adaptive flexibility creates a reliable barrier against leaks, while the high yield strength minimizes compression set over time.
Multi-Media Compatibility: With inherent oil-resistant properties, these gaskets excel in hydraulic sealing applications such as cylinder head assemblies. Their non-reactive nature also makes them suitable for high-vacuum environments where outgassing is a critical concern.

Custom Thickness Capabilities

Standard Range: Available in thicknesses from 1.0mm to 6.0mm, catering to most industrial needs.
Specialized Thickness Solutions: For applications requiring enhanced durability, our 3+2 composite design (Paper-Metal-Paper-Metal-Paper) utilizes advanced multi-layer bonding technology to achieve thicker profiles without compromising flexibility.
Custom Fabrication: Beyond standard sizes (500x500mm, 500x1000mm, 500x1500mm, 1000x1000mm, 1000x1500mm), we offer fully customized sizing to match unique equipment specifications.

Application Engineering Guidance

Selecting the optimal thickness is critical for balancing performance and cost efficiency. As a best practice, specify the thinnest viable material for your application to maximize sealing effectiveness. Uncertain about material selection? Our gasket engineering team provides comprehensive support, including access to our material selection tool and elastomer compatibility guides.

Bespoke Solutions Available

If standard products don’t meet your requirements—whether for specialized deep-cooling systems, high-vacuum chambers, or unique dimensional needs—our technical specialists are ready to collaborate. We offer fully customized material formulations and fabrication processes to solve the most challenging sealing applications.

Invest in our high-temperature resistant graphite gasketing today and secure a reliable sealing solution that combines longevity, performance, and engineering flexibility. Contact us to discuss how our products can optimize your equipment’s operational reliability in the most extreme environments.
