Technical Information

Material 100% expanded PTFE (polytetrafluoroethylene), with multidirectional strength
Chemical Resistance Chemical resistance to all media pH 0-14, except molten alkali metals and elemental fluorine.
Operating Range

The maximum applicable pressure and temperature depend mainly on the equipment and installation.

  • Typical use: -60°C to 230°C (-76°F to 445°F); industrial full vacuum(1) to 40 bar (580 psi)
  • Maximum use: -269°C to 315°C (-452°F to 600°F); full vacuum to 210 bar (3000 psi)

For applications outside the typical use range, Gore recommends an application specific engineering design calculation and extra care during installation. Also, consider retorquing after a thermal cycle when the equipment has returned to an ambient temperature condition. Please contact Gore if further guidance is required.
Shelf Life ePTFE is not subject to aging and can be stored indefinitely.

(1) absolute pressure of 1 mmHg(Torr) = 133 Pa = 1.33 mbar = 0.019 psi
