Style 642 AR Grooved Metal Core with Integral Centering Ring

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

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
