Flexible Graphite Gasket Sheets for High-Pressure Industrial Valve Sealing
Discover top-quality flexible graphite gasket sheets tailored for high-pressure industrial valve sealing right here. Our graphite gasket sheets are available in thicknesses ranging from 1.0 to 3mm. As a best practice, choose the thinnest sheet suitable for your specific application to ensure optimal performance.
Our flexible graphite gasket sheets are crafted with two layers of pure flexible graphite sheet, sandwiching a 0.2 - 0.25mm perforated metal insert. The metal insert can be 0.2 - 0.25mm carbon steel (also known as tinplate), or options like ss201, 304, 316. You can select from graphite with carbon contents of 95%, 97%, 98%, or 99%.
- Superior Adaptability and Durability: These gasket sheets offer excellent adaptability to various industrial conditions. They are highly durable, ensuring long - lasting performance in high - pressure and high - temperature settings.
- Outstanding Sealing Performance: With a focus on high - pressure industrial valve sealing, our graphite gasket sheets provide reliable and effective sealing, preventing leaks and ensuring system integrity. There is no risk of delamination, and they offer a high yield.
- Economical Solution: They serve as an economical choice for sealing in applications such as steam cycling or exhaust systems. Ideal for use as an exhaust or manifold gasket material.
- High Oil - Resistance: The sheets exhibit good oil - resistance, making them suitable for applications where exposure to oils is expected.
- Exceptional Temperature and Pressure Resistance: Specifically designed to withstand high temperatures and pressures, they are perfect for high - pressure industrial valve sealing requirements.

Designed for high - pressure industrial valve sealing, these flexible graphite gasket sheets are also suitable for oil sealing, gasket applications, and as cylinder head gaskets. They are commonly used in steam cycling and exhaust applications where high - pressure and high - temperature resistance are crucial.
- Thickness: Available in 1.0 - 6.0mm thicknesses. For thicker options, we offer the 3 + 2 type (with a product section from top to bottom in the order of Paper - Metal - Paper - Metal - Paper) and utilize multi - paper bonding technology.
- Dimensions: Standard sizes include 500500mm, 5001000mm, 5001500mm, 10001000mm, 1000*1500mm. However, we also provide customized sizing to meet your specific needs.
