Black Teflon PTFE Orings


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: Low Temp: -200°C (-328°F) to High Temp: 260°C (500°F).


Solid PTFE o-rings are used virtually in every industry as either a primary o-ring or a backup ring. They are excellent seals in applications that are subject to harsh chemical exposure, extreme temperature or pressure, as well as dynamic applications. PTFE o-rings demonstrate excellent abrasion resistance and performance in weathering elements such as ozone, UV, and water. The major limiting factor of PTFE is the inability to compress easily, which similar to its low coefficient of friction, may not be ideal for some o-ring sealing applications. While limiting for some applications, these factors may also perfectly qualify PTFE for use in other applications (such as dynamic sealing applications). PTFE also exhibits good insulation qualities and has seen use in cables and electronic assemblies.
