API 11B sucker rod couplings, 1" Slim hole

Made in accordance with API 11B, the couplings are high in quality and reasonable in price. The basic material is AISI 5140.

YUNSHENG is the professional manufacturer of API sucker rod couplings and haa been in this business for many years.

YUNSHENG got the API certificate on June 1, 2009. The couplings have been exported to many countries and enjoy high reputation from our customer.

API 1” Class T Slim Hole Sucker Rod Coupling

1)Material: AISI 5140

2)Standard: API Spec 11B 

3)Specification:

    OD: 2" (50.80mm)

    ID: 1-3/8"(34.93mm)

    Length: 4" (101.6mm)

    Weight: 0.58kg

4)Other Size: 5/8”; 3/4”; 7/8”; 1-1/8"

5)Features: The Class T sucker rod couplings are manufactured with a through hardness of between 16 and 23 Rc. This results in high tensile and fatigue strength for the sucker rod couplings. The outside diameter of the sucker rod couplings is smooth to minimize stress concentrations, and an accurate chamfer allows for controlled contact stress.
