The CG gasket utilizes an external ring where the ID is grooved to insert a sealing element. The external ring or centering ring is designed to properly guide the gasket on a bolted flange accurately centering the gasket. The centering ring also provides additional radial strength to prevent gasket blowout and acts as a compression limiter.

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
