      PTFE gaskets or PTFE retaining rings do not have sealing function. As the name suggests, they are protective and supporting components made of extrusion resistant materials, usually with rectangular cross-sections. They are installed together with elastic seals in grooves, preferably with corresponding O-rings for static sealing purposes.

Due to the tight fit of the retaining ring in the groove, they prevent the compressed elastic seal from being squeezed into the sealing gap。
