ABSTRACT:
A compact well head adapter having a uniform design for a variety of well casing sizes. An annular adapter body includes a lower portion threaded for connection to a well casing, an upper portion threaded for connection to a fluid conductor, and a bore for the transfer of fluid between the casing and the fluid conductor. A removable annular shield is removably connected to the upper portion of the adapter body to protect the upper threaded portion from damage in handling. The lower threaded portion can be varied in size to fit different size well casings and the upper portion remains the same size for connection to the fluid conductor and to the annular shield. The adapter is supported by a swivel to facilitate rotation of the adapter as the adapter is threaded onto the well casing.
