TESGRAF®

EXPANDED MINERAL GRAPHITE PRODUCTS

TESGRAF® is a wide range of Expanded Mineral Graphite Products, sheets and gaskets with a very high temperature resistance.

Natural graphite is processed with special machinery that enable to realize a wide range of products - sheets, tapes, packings, rings, textiles - to be used especially for the production of industrial gaskets for universal applications at high temperatures and pressures.
The TESGRAF products of TESPE are made of pure Expanded Graphite with very low ash content and they are flexible, soft, incombustible, waterproof to gases and liquids, resist most process fluids, high thermal shocks, high temperatures and pressures..

Tesgraf Sheets

Pure Graphite Gasket Sheets

Pure Graphite TESGRAF SHEETS are particularly suitable for the production of flat cutted gaskets for heavy duty applications in the presence of high temperatures and pressures, vapors and chemically aggressive fluids (with the exception of highly oxidizing agents), diathermic oil and universal uses where the gaskets in asbestos-free, PTFE or other material are not suitable.

Tesgraf Tapes

Pure Graphite Laminated Tapes

Pure Graphite TESGRAF TAPES are mainly used for the production of ring seals for valve stem or pump, or as filling of spirometallic and metalloplastic gaskets. Pure Graphite Tapes TESGRAF TAPES are produced in plain version and in pleated versions. The plain type is also used for series production of high density gasket rings, by means of special presses. The pleated type, thanks to its special high flexibility and compressibility structure, is mainly used for "on-the-spot" maintenance, as a self-modeling gasket seals, wrapping it directly on the stem of shaft of the valve or the pump.
