FEP PFA orings in PTFA wrap
provide a durable and effective seal, making them ideal where they should meet the highest requirements. They are used in many industries from the oil industry, through chemical processing, pharmaceuticals, paints and dyes, printing and marking equipment to liquid liquid transfer.  FEP orings    are mainly recommended for static applications, but they also work well in slow moving applications. They find many supporters because they are a more economical alternative to ffkm or  ffpm or ffpm.
Fep PFA
    orings Viton ®, Siliconeor EPDM (from which the core is formed) and a thin FEP or PFA coating are used in the orings.  Thanks to this,  the so-called  Teflon orings gain resistance to high and low temperatures (a range depending on the material from which the core is made) and almost universal resistance to chemical compounds. Perhaps  Teflon oring  is the answer to your needs. It can be used at elevated temperatures and high pressures, plus it is distinguished by its low gas permeability and very low coefficient of friction.
