Hinged Adaptor Bushing

Frank’s Hinged Adapter Bushing is designed to take the place of the rig’s solid adapter bushing, readily adapted to National, Emsco, or Oilwell 49 1/2” Rotaries, and will accept 37 1/2” Master Bushings of the same makes.

 

Frank’s Hinged Adapter Bushing simplifies running strings with well head housings or other assemblies larger than 37 1/2”, since it can be removed and reinstalled around the pipe.

 

Frank’s Hinged Adapter Bushing will also accept a Varco FMS-375 500 Ton flush mounted slip body without the need for adapter rings, Frank’s RS-250 rotary spiders, Frank’s Universal Casing Bushings, as well as Frank’s 16”-20” Flush Mount Spiders.
