Selecting the right gasket for the application

Non-asbestos gaskets are made from a combination of various materials such as rubber, fibers, and chemical additives. These components are blended together to enhance heat resistance and chemical resistance. The mixture is then processed and rolled into sheets, making it suitable for a wide range of applications.

Because of their composite structure, non-asbestos gaskets tend to have more microscopic voids compared to metal gaskets, PTFE (Teflon) gaskets, or other solid gasket types.

Therefore, when used in gas or high-temperature steam lines, it is recommended to select non-asbestos gaskets with a thickness not exceeding 1.5 mm. This helps minimize internal voids, reduce the risk of leakage, and ensure better sealing performance under high-temperature conditions.
