Product description

Self-adhesive flange tape made of expanded PTFE with higher specific gravity. Allows sealing of uneven and damaged flanges at lower tightening torque. Use where residual seal thickness is required. Compared to POWERflon UNI, the smaller width of the tape seals at higher pressure with lower Mu.

  • Small change in width after loading.
  • Allows sealing of uneven and damaged flanges at lower tightening torque.
  • Use where residual seal thickness is required.

Used on flanges, heat exchangers, chemical container lids, partition planes, manholes.
