The LG gasketing sheet made by pure expanded graphite are great for applications on low pressure flanges. The pure graphite has modest tensile strenght and therefore it's always recommended the thickness from 0.4 to 1.0 mm for the best sealing.
Pure graphite C > 98.0 %
Flat graphite gaskets for low pressure applications. Graphite isn't suitable for oxidizing fluids.
