PTFE TFM™ envelope gasket, with inner diffusion barrier and PTFE insert

  • Article Number: 7145ED10
  • Material: 7145
  • Profile: ED10

The cover is made of TFM™ 1600 with an internal diffusion barrier (width 3 mm). The insert is made of PTFE quality UNIFLUOR® 7550 with a thickness of 3 mm. Leading enamel flange manufacturers recommend this gasket up to a nominal diameter of DN 200. For larger nominal diameters, the use of the IDT profile ED30 gasket system with a thickness of 6.5 mm is recommended due to its higher compensation capacity.
