WT-E PTFE gasket tape

WT-E PTFE gasket tapes consist of 100% expanded PTFE (ePTFE) of higher density with mono-directional fibrous structure.


Advantages and possible applications

WT-E PTFE gasket tapes are suited for sealing in frictional connection.
They are suitable for all kinds of flanges and flange surfaces. Such as: steel, aluminium, rubber lined surfaces, GFK etc.

WT-E PTFE gasket tapes are used in sealing of: Machine enclosures, mixers, sight glasses, containers etc.

WT-E PTFE gasket tapes offer a wide range of benefits like:

  • Easy and quick installation
  • Due to the higher density and the achieved width/height proportion WT-E PTFE flat gasket tapes are especially suited for sealing flanges with large flatness imperfections or narrow surfaces.
