WT-M PTFE gasket tape

WT-M PTFE gasket tapes consist of 100% expanded PTFE (ePTFE) with a mono-directional fibrous structure.


Advantages and possible applications

WT-M PTFE gasket tapes present a very convenient and universal sealing, can be used for nearly all areas of static sealing techniques. Very few cross sections (width/thickness) cover most application requirements.
Hence, WT-M PTFE gasket tapes offer a wide range of benefits like:

  • Low storage costs and economic maintenance
  • Easy and quick installation
  • Minimal downtimes or idle states

WT-M PTFE gasket tapes have a very low cold flow, in comparison with common PTFE gasket tapes. WT-M PTFE gasket tapes are suited for sealing in frictional connection. WT-M PTFE gasket tapes are appropriate for all kinds of flange connections, heat exchangers, containers, hand- and manholes, pumps, centrifuges, reactors and many other applications.
