4)Other Size: 3/4”; 7/8”;1”; 1-1/8"5)Features: The Class T coupling is manufactured with a through hardness of between 16 and 23 Rc. This result in high tensile and fatigue strengh for the coupling. The outside diameter is smooth to minimize stress concerntrations, and an accurate chamfer allows for controlled contact stress. The threads are rolled full form which results in compressive stresses at the thread root and improved fatigue resistance.
