The patented GT-M™ connection is special version of XT-M™, the industry’s first gas-tight, pressure-rated rotary shouldered connection.  The GT-M connection features a radial metal-to-metal internal pressure seal with the external torque shoulder providing a secondary seal.

The internal metal seal is generated by radial interference, reducing the effects of tensile load. Capable of resisting high-pressure liquids and gas, the seal integrity is not affected by multiple trips.

The GT-M connection is available only for 6-5/8” sizes.  Compared to the XT-M connection, the GT-M connection does not have an internal torque shoulder providing reduced makeup torque.

Due to the large ID, GT-M drill strings are well suited for invention risers.

GT-M connections are not interchangeable with any other rotary-shouldered connection.
