3. ANTI-EXTRUSION RINGS

Anti-Extrusion Ring

Function: to provide firm support to the stripper rubber packer elements in a CTU stuffing box to prevent them from extruding too readily.

Material: based on reinforced PTFE, the product shows strength in resisting change of shape under pressure, but creep yields at extremes, while remaining surface lubricated by the PTFE so as not to bind in the box.
