Carbon & Graphite Gaskets 
Request a Quote
Carbon Fiber and Graphite Flake
sheets are able to withstand significantly more aggressive
chemical environments (other than powerful oxidizing
environments) and higher pressures than standard
non-asbestos gasket materials. Metal inserted materials are
able to operate at even higher pressures. In reducing
environments, pure graphite can handle up to 5000F.
Mercer carries Garlock, Thermoseal and Graphoil brands of
carbon and graphite based gasket materials. These materials
are available in thicknesses 1/32" through 1/4".

effective high temperature / pressure material.
Graphite gasketing materials are made from pure
exfoliated exhibiting excellent sealing characteristics,
withstanding a high range of temperatures pressures and
chemicals. The homogeneous material is free of
respirable fibers, binders and additives. Standard
grades are 95% - 98% pure graphite sheet. Graphite is
extremely conformable giving it the ability to flow into
flange surface imperfections. Its low permeability and
chemical resistance make it an ideal choice as a sealing
material. Mercer offers a wide range of Graphite with
various core materials such as tanged stainless of Foil
stainless steel reinforcement.
