Non Mettalic Gasket
Non-metallic gaskets, on the other hand, are usually made from composite sheet materials such as aramid fiber, glass fiber, or PTFE, and are used with flat-face and raised-face flanges in low-pressure applications. No metals are used in their construction.

Full-face non-metallic gaskets are suitable for use with flat-face flanges; flat-ring gaskets are used with raised-face flanges. Non-metallic gaskets — also called soft gaskets — are easily compressed under bolt load. Since they don’t contain metal, they offer superior corrosion resistance, but can only handle a limited range of temperature and pressure. Non-metallic gaskets are commonly used in pipe flanges, heat exchangers, compressors, and bonnet valves. These gaskets are available in a variety of cut shapes.
Non Mettalic Gasket Advantages
- Very dense sealing material
- Affordable and great availability
- Adapts perfectly to the flange
- No creeping
- Easy to cut/punch to size
- Extremely chemical resistant
