Applications and Key Features

The metallic reinforcement enhances material handling. This design is engineered for applications where gasket structural integrity is a critical requirement.

PART NUMBER ANALYSIS

To properly select or replace this material

Key Design Features

The tanged mechanical bond ensures structural integrity without relying on the adhesive technology found in FGL316. The insert also enhances cut gasket rigidity during handling prior to installation.

Key Criteria for Selecting a Replacement

Selection must account for bolt load, gasket seating width, thickness, and cut geometry. A reinforced core does not eliminate the need for proper bolted joint assembly control.

To compare constructions: Garlock GRAPH-LOCK 3125TC and TEADIT GE 1520. While the metallic insert reinforces the flexible graphite, its thickness, geometry, and bonding method vary depending on the grade.

REPLACEMENT TO BE EVALUATED

Compare designs and alternatives

KEY COMPARISON CRITERIA

FGT316 is distinguished from FGL316 by its mechanically bonded 0.004″ tanged stainless steel core, as opposed to an adhesively bonded 0.002″ foil insert. FGS95 homogeneous graphite does not feature this core.
