Double Jacketed Metal Gaskets

The metal jacketed gaskets are fabricated with a metallic shell with a soft filler material encapsulated between the metals in overlapping fashion. 3S – Superior Sealing Services stocks many exotic alloys and fillers to quickly manufacture these in custom sizes and shapes dependent upon the customers application. Double Jacketed gaskets are still the most commonly used gaskets in heat exchangers.  These can be made to virtually any size, shape, and configuration. Another gasket in this family would be Solid Metal Core with or without soft sealing material on both sides. The Solid Metal gaskets require sizable clamping force to seat, and it is always good practice to choose softer or same material as flange in order to prevent damage to flange faces.
