Elastagraph Gaskets

Elastagraph gaskets are made by infusing a seamless layer of flexible graphite at varying densities and thicknesses over a corrugated metallic core; the standard core being 316 Stainless Steel, with other alloys available on request. Elastagraph utilises a unique corrugated pattern which increases the depth of the groove and the pitch of the corrugation. This greatly improves the gasket’s seal-ability over other corrugated designs.

The increased pitch and groove depth increase Elastagraph’s recovery or ‘spring back’ and reduces the surface area of the gasket for a greater unit load at initial torque, as well as a lower minimum seating stress. This ensures maintenance of bolt load during thermal cycling.

The proprietary production process allows the graphite to be applied without the ‘seam’ that is present in other gaskets fabricated from flexible graphite sheets. Furthermore the inner diameter of the Elastagraph gasket is encapsulated by high density flexible graphite providing total corrosion resistance and increasing seal-ability over traditional laminated designs.

Unlike other corrugated designs Elastagraph does not contain any adhesive that would normally contribute to bolt torque loss.
