The Premium Connection of Fox is an advanced premium threaded connection for tubing, casing and line pipe. Its innovative thread geometry achieves substantial reductions in peak tooth loadings both on make-up and in tension.
The patented triple radius contour seal ensures superior over torque resistance and greatly increased seal stored energy. The result is a significantly reduced tendency to thread galling, combined with outstanding performance even under extreme loadings and rapid temperature change conditions.
Threaded line pipe requires high fatigue performance under long term exposure to cyclic bending in combination with internal and external pressure and axial loadings. The Premium Connection of FOX has been well proven in use worldwide.
