GRAPHONIC®
Metallic Gasket
The superior technology of the GRAPHONIC® fam-
ily of gaskets ensures excellent sealing performance
and reliability, even in the most diffcult applications.
Each of the three styles combines a corrugated metal
core with a compressible sealing element of various
materials, for resistance to a wide range of harsh condi-
tions, including extreme temperature, corrosive chemi-
cals, and thermal cycling.
Applications
■ Valves ■Heat exchangers
■Pumps ■Vessels
■Flanges
