PTFE-packings strand-die face extruded, graphite-free

  • Compact, dense cross-section, self-lubricating and shaft-friendly. Very good chemical resistance.
  • Shaft wear is reduced due to embedding of solid particles for abrasive media.
  • Recommendation: Installation with encapsulation rings prevents gap extrusion.
