KWO® Universal HD

gasket tape with a rectangular cross section


KWO® Universal HD is gasket tape of monoaxially expanded pure PTFE with a high density.

The tape is characterised by a rectangular cross-section and a relatively small width. The high density of the material and the special cross-section of the tape allow the sealing of very uneven sealing surfaces even at a low gasket stress.

KWO® Universal HD sealant tape is suitable for delicate sealing applications on surfaces vulnerable to tension, such as glass or ceramics. The tape can also be used to seal weak flanges subject to considerable deformation, for example glass reinforced plastics (GRP), plastic fittings and ventilation facilities.




  • low diffusion leakage
  • excellent adaptability to all surfaces
  • easy filling of flange gaps
  • harmless for food-contact applications
  • UV resistant, non-ageing
  • nontoxic, biologically inert
  • non-flammable


  • flange connections, tank sealings
  • entilation systems
  • apparatus constructions
  • machine housings
  • pumps
  • food processing systems
  • FDA 21 CFR 177.1550 compliant
  • EC1935/2004 - suitbale for food applications
