ShareDescription
The J&N Stripper Packer is designed to pack-off on coiled tubing as it is stripped in and out of the well. The over/under and dual side door models provide two independently hydraulically actuated packers respectively. The unique design allows the operator to use one packer while the other is kept as spare. When the first packer fails, the second packer is available. This function effectively doubles the time between packer changes. Packer change is easy and available when the coiled tubing is still in the well.
We can provide customized stripper packer depending on customer's requirements.
