  • Adhesive Backed Tapes

    Thermafoil® Adhesive backed products consist of several varieties of Thermafoil material and backing products. Your design parameters will dictate the proper structure.  Standard products, such as adhesive tape, can be used as a do-it-yourself gasket or as a thread sealant.  As a gasket, the self-adhesive, all graphite tape is available in plain or crinkle style, […]

  • Balance Gasket

    Balance gasket is football shaped and works on a two bolt flange. When you get to the 6 and 12 o’clock position, there’s nothing there Engineer figured on a way to make the positions denser where they had no bolts and thinner in  areas where bolt load was at it’s peak.

  • Balance Gaskets for Load Compensation

    Clamp load is factor that can’t be ignored when it comes to gasket performance. A two bolt flange for instance, means your hands are tied when trying to create even gasket loading. But EGC has created a methodology that helps spread the load by increasing the density of the material (where there is no bolt) […]

  • Control Valve Balance Seal Design

    Most graphite-based seal designs create high-friction and stem effort during operation and many actuators may over-compensate causing inaccurate positioning of the plug or piston causing system inefficiency.  EGC does it differently.  We’ve found methods to greatly reduce friction during valve operation while achieving a tight shut-off when it really counts.  And the beauty of it […]

  • Conventional Pressure Seal

    The Conventional Graphite Pressure Seal is a composite design that combines stainless steel caps top and bottom and high-density Thermafoil® flexible graphite. While the flexible graphite conforms to irregular sealing surfaces and adjusts to fit out-of-round and oversized conditions, the stainless steel caps provide strength and anti-extrusion capabilities. EGC developed the conventional graphite pressure seal […]

  • Cut and Coined

    All Thermafoil® parts, constructed in the same manner as our standard die cut laminates, are coined to achieve more precise control resulting in a higher pre-installed density.  By coining, we can provide contoured or shaped product cross-sections to custom fit non-rectangular seal cavities.

  • DGI Wire Mesh Rings

    An EGC Wire Mesh Packing Ring eliminates packing contamination in process pumps.  When an engineer presented the idea to EGC’s President, his response was “that’s a damned good idea” and the name, DGI was adopted. The molded product is manufactured from Nickel 200, a non-galling material with a high corrosion resistance to caustics.  The DGI […]
