Abstract

A gasket (10) for sealing flanges (80), formed of a plurality of expanded intercalated graphite worms (75) compressed together and defining an annular opening (12) therethrough, with the opposing sides (14) of the gasket (10) defining respective sealing surfaces having a first elevation (20) and a first density, with a flange-like curb (26) on a perimeter edge (28) of the annular opening (12) and extending outwardly on opposing sides of the sheet to extents (30) having a second elevation greater than the first elevation, a second density less than the first density, and a first porosity. The curb (26), being compressed between parallel flange surfaces (80), thereby defines a closed face on the inner diameter of the gasket having a third density greater than the second density and a second porosity less than the first porosity, for resisting leakage through the gasket (10) while sealing a flange. A method of sealing a flange joint is disclosed.
