ABSTRACT OF THE DISCLOSURE A connector for flush or near-flush connectors for pipe casings is disclosed, featuring a square or near-square torque shoulder (within manufacturing tolerances and including a slight reverse angle of less than 5 degrees) located at the outermost area of the connector, which does not seal high external or internal pressures. An adjacent radial inter- ference-fit seal is designed to seal against collapse pressure but not against high interstitial pressure within the box and pin threads. The connector is held together with a hooked thread form which maintains the mechanical integrity of the joint as interstitial pressure passes between the pin and box threads.
