Grafoil Gasket Material

Grafoil ® Gasketing

GRAFOIL® flexible graphite was the first fluid sealing material made exclusively from pure, natural graphite flake.  Its resistance to heat, fire, corrosion and aggressive chemicals make it the most universally applicable sealing solution on the market today.  Like no other , GRAFOIL products provide a tight seal after repeated exposure to the harshest environments.

Grafoil is a product of Graftech Inc.
