Style 642 AR2 Grooved Metal Core with Floating Centering Ring

Serrated solid metal core gasket faced and floating centering ring with soft, deformable sealing material such as flexible graphite, PTFE or THERMa-PUR®.

FEATURES and BENEFITS

  • Seals less-than-perfect flanges to form a tight connection
  • Performance replacement for jacketed heat exchanger gaskets
  • Fire safe—passed API 6FB fire tests
  • Available in HEAT SHIELD® configuration for high temp applications above 850°F / 454°C
  • Solid metal core resists cold flow, over compression, and blowout
  • Rigid core provides exceptional stability, even in large sizes, and facilitates handling and installation
  • Available in wide variety of metals
  • Seals under low stress—ideal for lighter weight flange designs
  • Withstands extreme fluctuations in temperatures and pressures

SPECIFICATIONS      

  • Gasket Factor “m” = 4.0
  • Gasket Factor “y” = 1,000 PSI (NOTE: When designing flanges, Garlock recommends using a "y" of 4,000 PSI to ensure the flange design is thick enough to avoid excessive deformation when assembled and heated.)                                                                  

APPLICATIONS
