Sucker Rod CouplingAdvantage:

Sanmon Class T couplings for sucker rod are manufactured as per API Spec 11B standard. For the thread cutting, we plant tap extruded thread in room temperature by reseating material rather than cutting material in making coupling threads. This craft results in a compressive stress at the root of the thread, giving better maximum strength and overcame the traditional weak point of cut-thread couplings.

Our Class T coupling is using AISI 5140 /1045 to manufacture. The coupling is coated using phosphate chemical treatment. The couplings are available in full size, slim hole and Sub OD
