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.
