Flexpro Graphite Gasket
Product Resources
The Flexpro gasket exhibits excellent compressibility and recovery characteristics, maintaining joint tightness under pressure and temperature fluctuations, temperature differential across the flange face, flange rotation, bolt stress relaxation, and creep. Suitable from vacuum to extremely high pressure applications.
Thermiculite CGI
Product Resources
Suitable for use with flat face and raised face flanges and specified for high pressure/temperature service or where corrosive or toxic media are present.
Style CG - Flexible Graphite
Product Resources
Utilizes an external ring which accurately centers gasket on flange face: provides additional radial strength to prevent gasket blowout and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face flanges.
