100% external pressure integrity created by toroidal external metal to metal seals, promoting consistent seal contact loading for all combined-load conditions.
Superior compression strength, up to 50%, obtained by optimized torque shoulder and controlled 20 degree stab flank reduced clearance. Hooked threads provide high tension strength, up to 78%, by resisting the tendency for radial disengagement, virtually eliminating thread jump-out.
