Polytetrafluoroethylene Teflon O-Rings

Polytetrafluoroethylene Teflon O-Rings

Polytetrafluoroethylene (PTFE) is a high molecular weight polymer, one of the most versatile plastic materials known and useful for a large range of products for applications excluded to other materials. Temperature Range: Standard Low Temp: -200°C (-328°F) Standard High Temp: 260°C (500°F)...

Polytetrafluoroethylene Teflon O-Rings

PTFE O-rings are used where many other materials and elastomers are unsuitable for the application conditions, i.e. friction, chemical resistance and temperature.

PTFE O-rings are used for a wide range of applications in many industries, including aerospace, food and drink, pharmaceuticals, telecommunications and semi-con.

PTFE O-Rings can be used for axial static faces or flange chemical resistance. PTFE is the most chemically inert of the O-ring materials.

PTFE is resistant to most chemicals including acids, bases, oils, steam and other chemicals. It is also very tough and abrasive resistant, even at elevated temperatures.

PTFE is chemical resistant, non-stick and electrically resistant and is superior to most other materials in these conditions.


Hardness is measured using the Shore D scale and is usually 54 – 57° (this equates to approx. 9° on the Shore A scale.)

Seals fabricated from this material feature outstanding weather resistance, high resistance to ozone, and high resistance to the degrading effects of exposure to such solvents as acetone, MEK, and xylene. Possessing average elastomer characteristics of 2,500 to 3,500 psi tensile strength, and 300% elongation, they are tough, impact resistant, low friction, non-twisting performers over an extremely wide temperature range.
