2)Standard: API Spec 11B 

3)Specification:

  Full Size:     O.D.: 1-1/2(38.10mm)

                       I.D.: 15/16(23.81mm)

                       Length: 4(101.6mm)

                       Weight: 0.56kg

  Slim Hole:    O.D.: 1-1/4(31.80mm)

                       I.D.: 15/16(23.81mm)

                       Length: 4(101.6mm)

                       Weight: 0.41kg

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 HRC. 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.
