ABSTRACT:
A hydraulic control communication nipple for switching control fluid in a fluid passageway from one location to a second location. A metal plug is aligned with a portion of the fluid passageway and is positioned to be engaged by a vertically moving sleeve and moved into said portion to shut off fluid communication to a first location. The plug is a frangible plug that includes a longitudinal axis extending vertically into the passageway and includes threads screwed into and forming a metal-to-metal seal with the passageway. The movement of the plug into the portion of the passageway may also open communication of the passageway with the second location. For alternately opening the passageway to a second location, a metal breakable screw having a longitudinal axis extending vertically into the passageway adjacent the second location has threads screwed into and initially blocks the passageway with a metal-to-metal seal. The screw includes a cavity exposed to the passageway. The vertically moving sleeve is connected to the screw and is adapted to break the screw in tension and expose the cavity to the interior of the well tool.
