The Paragon II Retrievable Medium Expansion Tubing Packer is a higher expansion version of the standard Paragon Packer. It contains all the same features that create the high utility and high performance of the other versions of the Paragon Packer while offering a smaller run in hole outside diameter (OD). This packer version is used when there is a need to drift through smaller inside diameter (ID) tubing features that the standard Paragon Packer versions will not drift through. The TTS Medium Expansion Paragon Packer utilizes our newly developed Medium Expansion Hercules Sealing Stack. This sealing stack has been successfully tested to API 11D1 V3 specifications and is currently rated at 5000 psi at 300 degrees Fahrenheit. Other validation ratings may be available upon request.
