Non-Asbestos Gasket Sheet

A gasket is a compressible material, or a combination of materials, which when clamped between two stationary members prevents the passage of the fluid across these members. To prevent the passage of fluid, the gasket must be able to flow into (and fill) any irregularities in the mating surfaces being sealed, while at the same time be sufficiently resilient to resist extrusion and creep under operating conditions. The seal is affected by the action of force on the gasket surface (usually by bolts), which compresses the gasket, causing it to flow into any surface imperfections.
