ULTRA™ DQX
The proprietary ULTRA™ thread design reduces hoop stresses on the coupling and provides adequate torque capacity for shales applications.
ULTRA™ DQX
FullContact™ threads
Provide high tension and compression efficiency, and even stress distribution.
Positive torque stop
Pin-to-pin back-up mechanism provides high torque capacity and compression ratings.
Run-out threads
Low interference run-out threads enhance fatigue life and maximize critical cross-sectional area.
ULTRA™ DQX
Featuring the patented ULTRA™ thread form with a pin-to-pin torque stop, this cost-efficient connection provides better performance than an API Buttress-compatible: improved sealability, galling resistance, lower running time. Supported by over 80 million feet of successful run history in major US shale plays.

- Deep stabbing, faster rig make-up
- Structural performance same as pipe body
- Reduced hoop stresses allow to minimize coupling OD
- Extensive testing to verify galling resistance
- Available with seal ring
