API 1" class t sucker rod couplings

1)Material: AISI 5140

2)Standard: API Spec 11B 

3)Specification:

   OD:2-3/16" (55.56mm)

   ID: 1-3/8"(34.93mm)

   Length: 4" (101.6mm)

   Weight: 1.13kg

4)Other Size: 5/8"; 3/4"; 7/8"; 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.
