Typical Hook-Up Of Seal Bore Packer With Millout Extension And Seal Bore Extension

Guides are threaded bottom subs for Seal Bore Packers, and can be ordered separately or as an integral part of the Packer. They are available as box thread down to accommodate Mill out Extensions or 

Seal Bore Extensions or pin thread down to make up with tail-pipe or  other accessories down the line. Mill out Extensions are furnished with the standard API tapered thread connections. Other threads are

available on request.

For Packers that will eventually be milled out using the Packer Milling Tool, the Mill out Extension  is used to provide the length and inside diameter necessary to accommodate the Mandrel and Catch sleeve of a

standard Milling Tool.
