The most field worthy connections for the oilfield. NS Premium Joints all share a two-step pin nose which ensures rugged, tolerant. high performance gas-tight connection even in critical environments such as high compression, bending or fatigue resistance.
The "Two-Step pin nose" allows the metal to metal seal to be protected from running and over torque damage by two stout torque shoulders. The make-up mark on every pin verifies the torque shoulders are engaged and is easily checked externally after make-up. All coupled connections have a "Thread Lubricant Pressure Release Feature", allowing these connections to be less sensitive to "over doping" problems than other thread technologies. These connections are characteristically low in stress. These features make the NS Connection Technology threads the best choice ever in the most severe conditions.
