Garlock Series 600 Metallic Gaskets
Gasket Styles
 |
| Style 600- Corrugated Solid Metal A plain, all-metal corrugated gasket for use in low pressure applications that require a thin line contact because of weight limitations. Corrugated gaskets are a versatile sealing element where available bolt loads are low. Depending on the materials and construction, these gaskets can be very resilient. |
 |
| Style 606- Solid Metal with Flexible Graphite Covering This gasket is identical to the plain solid metal gasket (Style 640), covered with a layer of flexible graphite. This covering layer will fill flange imperfections sometimes found in flanges that have not been properly maintained. |
 |
| Style 620- Single Jacketed Generally used where the radial dimensions of the equipment sealing services only allow a narrow width seal. Single - Jacketed gaskets are constructed by encasing the soft filler material on one face and both edges. |
 |
| Style 623- Double - JacketedThe double - Jacketed gasket has good compressibility and resilience and is the most popular clad gasket manufactured. |
| Style 624- Single Jacketed Overlap Construction of this gasket offers more filler protection than the standard single Jacket design (Style 620). It is especially useful for applications where the radial dimensions do not allow space for a double - jacketed gasket. |
| Style 626- Double Jacketed Corrugated employs a corrugated jacket to increase resilience. Suited for circular and non-circular applications in cross section widths of 3/8" and wider, it is an improvement over the standard double- jacketed Style 623 gasket. If slight leakage should occur across the primary seal at the inner edge of the gasket, the concentric corrugations act as a labyrinth. |
| Style 627- Double Shell The double shell on this gasket allows greater hoop strength and rigidity with the addition of a completely overlapping inner seal. This gasket will withstand higher compressive loads common in high pressure applications. |
| Style 629- Double Jacketed Corrugated with Corrugated Metal FillerThe metal filler in Style 629 has greater resilience to problems resulting from temperature changes. This unique multi-ply construction provides a more resilient gasket that adapts to temperature and pressure cycling. The temperature limits of this gasket are governed only by the metal selected. |
  |
 Style 631- Two - Piece French TypeGarlock Style 631 is ideal for narrow circular applications that require a positive unbroken metal gasket line across the full width of the flange. The filler is exposed on the OD. This gasket is also available in one and three piece designs.
