Graphite Gaskets
Important: If you have any uncertainties about what material to use, just call us! We have employees that have been selling gaskets and servicing gasket applications for decades. We have sold gaskets in over 100 different materials! What follows below are generalizations for different categories of gasket materials. Use the information below only as a general guideline, and not as advice for your specific application.
Graphite Gaskets: Compressed graphite gaskets perform very well in harsh conditions. They can withstand higher temperatures and pressures than synthetic rubber or fiber-based gasket materials. Graphite gaskets can also withstand aggressive chemicals more than most other common gasket materials. Graphite gaskets are thus often used in chemical plants, refineries and paper mills.
