TXP® Buttress

The TXP® Buttress connection, with its special shouldered coupling design, offers extra torque and compression resistance as well as greater make-up stability than standard buttress connections.

By being API-compatible, operators can use standard API accessories and draw on a wide range of threading and repair shops. Seal Ring option is also available for TXP® Buttress, validated according to a major shale operator's specific testing protocol.
