Non-extrusion ring sets are placed on the top and bottom of the packing element. They act as a barrier between the moving parts of the Stripper Packer to prevent premature deformation or extrusion of the packing element. The two-part design has an angular seam cut to distribute the load evenly. This design also allows for easier installation while the coiled tubing is in the Stripper Packer.
