Product Description
FEP encapsulated o ring
All FEP Encapsulated O Rings available from Walle Seals are produced using the very latest technology and employing the most stringent quality control procedures to provide a pure, seamless encapsulation. They combine the benefits of a Viton or Silicone elastomeric rubber with the chemical resistance and mechanical properties of Teflon FEP/PFA polymer. The result being a chemically inert and sanitary assured O-Ring seal designed to overcome common sealing difficulties associated with it.
Technic data: Hostile Chemicals - Chemical attack and swelling are the primary cause of O-Ring failure. FEP polymer also has an extremely low coefficient of friction (.1 to .2) and very low permability to gases, making Chem-Rings a virtually universal seal for use in hostile environments.
Wide Temperature Ranges - Even at -60°C to +260°C, Teflon Encapsulated O-Rings withstand the most volatile media.
Material: Sanitary Requirements - The outer clear FEP/PFA Teflon tubing is specified to be manufactured from FDA, Sanitary 3A & USP Class VI compliant materials.
Compression Set - A common bi-product when utilising Solid PTFE/Rubber O-Rings. FEP/PFA Encapsulated O-Rings prevent premature compression set, due to the protection of the FEP/PFA Teflon encapsulation and retained elasticity of the Silicone or Viton core.
Expensive Perfluoroelastomers - Encapsulated O-Rings provide an economical alternative to expensive Perfluoroelastomers, such as Kalrez and therefore, vastly increase profitability.
Summary - FEP/PFA Encapsulated O-Rings offer far superior performance to solid PTFE O-Rings as these routinely suffer from 'Compression Set & 'Coldflow'. Near universal capabilities at a fraction of the cost of expensive Perfluoroelastomer alternatives and a one material replacement to the various common elastomeric O-Rings. (which will fail or suffer performance degradation in severe environments).
