Product main features:


  • The main function of this product is to ensure watertightness
  • PTFE offers excellent chemical resistance, pH0-14 (except for molten alkali metals and elemental fluorine), to oils, petrol, water, acids, etc
  • Flat gaskets made of expanded PTFE meet the food regulation CFR 21 FDA177.2600 and the EC 1935/2004 regulation.  They also comply with REACH. They can therefore be used in food and pharmaceutical environments
  • Expanded PTFE is a soft and flexible material that adapts easily to irregular surfaces. It is ideal for use in sealing flanges that are damaged or have irregularities
  • Expanded PTFE has excellent pressure resistance
  • Expanded PTFE tolerates temperatures ranging from -240 and +260ºC with peaks up to 315ºC
  • El material es muy suave, por lo que su uso se recomienda en bridas con riesgo de rotura a la presión por su fragilidad (cristal, cerámica)
Quality Control

Quality control of expanded PTFE flat gaskets


All flat gaskets in expanded PTFE manufactured in our production unit are subject to strict quality controls. They are therefore manufactured according to the pressure levels and dimensional standards of each country


  • Dimensional control which guarantees the accuracy of measurements subject to DIN, ASA, ASME, API standard
  • For standardized flat gaskets made of expanded PTFE, the classification is done according to their pressure (Kg/cm²) with the PN value. We have several PN values: PN10, PN15, PN20, PN25, PN32, PN40, PN50, PN65, PN80, PN100, PN125, up to PN500
  • Flat gaskets made of expanded PTFE are manufactured in our cutting section by trained and qualified personnel
