PTFE ring

The KWO® PTFE ring is based on the high-quality KWO® PTFE gasket sheet. For this reason the applications of a KWO® PTFE ring and a KWO® PTFE sheet are quite similar. Both products are used in applications where high temperatures or aggressive media play a decisive role. At KWO® we offer you the KWO® MultiTex® series consisting of the KWO® MultiTex® ring and the KWO® MultiTex® DK ring. The KWO® DK ring is tested and approved with test class "d" and is an ePTFE ring which is specially developed for steam boiler applications.

Information about the advantages, properties, applications and certificates of our KWO® PTFE rings can be found on the respective product page. Furthermore, the following technical data about the PTFE ring will be indicated:

  • material
  • temperature range
  • chemical resistance
  • pressure stability
  • physiological harmlessness

Moreover, you have the possibility to download the corresponding product data sheet. Here you will find everything you need to know about the PTFE ring. Information such as dimensions, resistance, areas of application, special properties or approvals and tests are stated there. In addition, you will get a detailed insight into the sealing characteristics as well as a short introduction to the assembly of the PTFE ring.
