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

Capabilities:

  • 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.)
  • Overview

Features and Benefits:
