• Cantilever design reinforces the connector, creates high contact pressure (leak resistance) in mating threads, limits expansion and distortion from make-up, reduces assembly pre-stresses, and minimizes thread galling.

• Easy stabbing without cross threading.

• Makes up to an internal torque shoulder in 5 to 6 turns and has API triangle stamp for secondary make-up verification. 

• Inspect with standard API and MRP gauges and procedures.

• Meets API Drift and OD Specifications.

• Maintains pressure integrity when special clearance.

• Eliminates mill side of coupling.

Options

• Special Clearance OD (SC): Specify GB W 3P SC when ordering. See Data Sheets for minimum special clearance OD and associated properties.
  

• Square Shoulder (SS): Specify GB W 3P SS when using connectors with side-door elevators.

• GB W 3P Connectors are stocked in 16" OD through 20" OD in K-55 Grade for use on K-55 and X-56 Casing.
