The CGI gaskets is best suited where high pressure and temperature is a factor or in applications where corrosive or toxic media maybe present. Like the CG profile, the CGI gasket includes an inner ring which has proven to be very helpful to eliminate inward buckling of the sealing element.

ASME B16.20 requires the use of CGI gaskets when PTFE is used as the filler in all ANSI B16.5 applications as well as:

     • Pressure Class 900, nominal pipe sizes 24” and larger
     • Pressure Class 1500, nominal pipe sizes 12” and larger
     • Pressure Class 2500, nominal pipe sizes 4” and larger

Thermiculite™, Flexitallic's® new high-temperature sealing material, is compromised of chemically exfoliated and thermally exfoliated vermiculite. This revolutionary new product simulates the structure of exfoliated graphite, with one notable exception-gaskets made with Thermiculite™ maintain their intergrity, even at high temperatures.  Thermiculite™ is thermally stable, ensuring against thermal oxidation, at temperatures in excess of 1800°F (Thermiculite™ 835).
