Product Description

High Temperature Resistant Graphite Sealing Gasket

Customized Thickness for Deep Cooling & Ultra-High Vacuum Industrial Applications in Heavy Machinery Manufacturing

Designed to perform in the harshest operating environments, our high-temperature resistant graphite sealing gaskets deliver superior stability for deep-cooling, ultra-high vacuum, and heavy-duty machinery systems. Combining premium flexible graphite with reinforced structural design and full customization, we provide reliable, long-lasting sealing solutions tailored to your exact equipment requirements. We primarily serve factory and industrial procurement clients, while also welcoming individual buyers—shipping is available worldwide exclusively from China, with individuals responsible for covering freight costs.

Custom Thickness & Dimension Capabilities

We specialize in customizable thickness and size solutions to match diverse industrial assembly and equipment needs.

Standard Thickness Range

Available from 1.0mm to 6.0mm to satisfy the majority of general and heavy industrial applications.
Specialized Composite Thickness Design

For applications requiring extra strength and durability, we offer a 3+2 composite structure (Paper‑Metal‑Paper‑Metal‑Paper). Using advanced multi-layer bonding technology, we produce thicker gaskets while maintaining excellent flexibility and sealing performance.
Custom Fabrication & Standard Sizes

Standard sheet sizes:

500×500mm, 500×1000mm, 500×1500mm, 1000×1000mm, 1000×1500mm

Beyond standard formats, we provide fully custom cutting and molding to meet unique equipment dimensions and installation requirements.

Application Engineering Guidance

Choosing the right thickness directly influences sealing performance and cost efficiency.

As a best practice, we recommend selecting the thinnest feasible thickness that satisfies your working conditions to achieve optimal sealing effect.

If you are unsure about material or thickness selection, our professional engineering team provides full technical support, including material selection tools and medium compatibility guides.

Product Technical Characteristics

Graphite gaskets offer excellent inherent stability for industrial media:

Excellent performance in steam systems
Good ozone resistance
Compatible with natural gas
High structural stability under thermal cycling
Low outgassing suitable for ultra-high vacuum environments
Strong oil resistance for hydraulic and power equipment

Key Structural & Customizable Options

Our gaskets feature a reinforced laminated structure for improved strength and reliability.

Component	Customizable Selection	Performance Benefit
Reinforced Insert	0.2–0.25mm perforated metal Carbon steel (tinplate), SS201, 304, 316	High tensile strength, dimensional stability, resists delamination
Flexible Graphite Layer	Dual-layer pure flexible graphite Carbon content: 95%, 97%, 98%, 99%	High purity, low outgassing, strong conformability, tight sealing
Overall Thickness	1.0–6.0mm standard Custom thickness available	Adapt to various flanges, vacuum chambers and heavy machinery

Performance Advantages

Extreme Environment Stability

Maintains integrity under wide temperature swings, thermal cycling, and high pressure in steam, exhaust, and power generation equipment.
Superior Sealing Performance

Multi-layer laminate design eliminates delamination. High compressibility and recovery ensure consistent sealing with minimal compression set over time.
Wide Medium Compatibility

Oil‑resistant, chemically inert, and low‑volatility, making it ideal for cylinder heads, hydraulic systems, vacuum equipment, and cryogenic cooling lines.
Fully Bespoke Solutions

If standard products cannot meet your requirements for deep‑cooling systems, high‑vacuum chambers, or special dimensions, our technical team will develop customized material formulas and processing solutions.

Procurement & Shipping Policy
