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:
- 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
Typical Applications:
- Valves
