  • High density for low permeability.
  • High tensile strength for greater working pressures.
  • Low crystallinity for longer flex life.
  • Material orientation for reduced stress concentrations and / or premature fatigue failure.

Note: Nom-Length is approximate and may vary.
Each PTFE expansion joint comes with metal flanges and tapped bolt holes that accommodate bolts in accordance with ANSI B16.5. Additional tapped holes are available for connecting Corning Style 11 flanges, by special order.
