Carbon & Graphite Gaskets

 

 

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".

Cost 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.
