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.
The PTFE TAS-006 o-ring can be referenced in one of four ways:
PTFE is a plastic compound as such; it does not have a ShoreA durometer rating. The PTFE compound name is polytetrafluorethylene which is a polymerization of tetrafluorethylene.
