One of the most versatile materials that gaskets can be made out of is graphite. Graphite gaskets can be used in environments that have temperatures ranging from -400 F to +875 F. Graphite gaskets provide an excellent dimensional stability and resist chemical attacks.
Many gasket materials stick to flanges and are difficult to remove when it’s time to clean flanges. Graphite gaskets are great to use because they don’t stick to flanges. Graphite gaskets are “slippery” and can be used in gasketed joints because the material moved easily to fill uneven gaps and can help correct flange deformation and/or surface imperfections.
