The ETANG Seal Bore Extension is designed for completions where a seal bore packer is used as the production packer and tubing movement is anticipated. The extension provides an extended seal bore length, allowing long seal assemblies to accommodate tubing movement while remaining fully within the seal bore throughout the life of the well.

　　Multiple ETANG Seal Bore Extensions can be joined together using concentric couplings to achieve greater seal bore length as required. These extensions are available for all standard seal bore packer sizes.

　　All ETANG Seal Bore Extensions are manufactured from materials complying with NACE MR0175 /API 5CT/ API 5CRA standard for SSC-resistant metallic materials.

　　Application:

　　Completions utilizing seal bore production packers where tubing movement is expected.
