Vulcan Type VG1D is square braided from continuous filament, texturized glass fibres reinforced with Inconel wire and impregnated yarn by yarn with pure Graphite powder and a corrosion inhibitor. Type VG1D Graphited Glass packing is designed as a substitute to classic Asbestos packing with high-temperature capability. The addition of Inconel wire reinforcement results in a true high-pressure and high-temperature traditional valve packing that has the advantage of being non-asbestos. - Impregnated Yarn by Yarn with pure Graphite powder and a corrosive inhibitor - Designed as a substitute to classic Asbestos Packing - High pressure and high temperature traditional valve packing
