WellBoss Polished Bore Receptacle is designed to extend the polished surface of the packer bore to permit the use of longer sealing units to compensate for the contraction and/or elongation of tubing.

The Polished Bore Receptacle and the Seal Bore Extension have similar functions; however, the Polished Bore Receptacle is used to connect to the top of the Packer whilst the Seal Bore is used to connect to the bottom of the Packer. Available in a complete range of sizes 2-3/8” to 9-5/8”” and length in 2ft increments. Other lengths are also available upon request.
