METALLIC GASKETS
Metal gaskets are designed to withstand extreme temperatures, pressures and chemical exposure. Available in standard and custom configurations, these rugged metal gaskets are made of a wide range of materials to accommodate all types of process applications.
Serrated solid metal core gasket faced with soft, deformable sealing materials such as flexible graphite, PTFE or THERMa-PUR®.
- Seals less-than-perfect flanges to form a tighter 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
- 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.)
- Valves
- Pumps
- Flanges
- Heat Exchangers
- Vessels
GRAPHONIC® Gaskets with flexible graphite sealing element are an excellent choice for heat exchangers and low pressure applications. The metal core is completely encapsulated by the compressible sealing element. Also available with an eyelet.
- Accommodates a wide range of temperatures
- Seals effectively during thermal cycling
- Fire safe - withstood API fire tests
- Chemically resistant
- Long service life
- Available in 150# and 300# Class
- Available with or without an eyelet
THERPHONIC® Gaskets with a THERMa-PUR® sealing element are an excellent choice for heat exchangers and low pressure applications, also requiring high temperature. The metal core is completely encapsulated by the compressible sealing element. Also available with an eyelet.

Single-jacketed gasket
Single-jacketed gaskets are constructed by encasing the soft filler material on one face and both edges. The metal jacket acts as reinforcement for the soft sealing material. Style 620 is generally used where the radial dimensions of the equipment sealing surfaces only allow space for a narrow width seal.
Double-jacketed metallic gasket
Double jacketed gaskets are constructed using one piece of metal to cover the bottom and edges of the soft sealing material, and an additional piece of metal to completely cover the face. Style 623 has good compressibility and resilience and is the most popular clad gasket manufactured
