Product Description

API 11B Class T and Class SM SH Sucker Rod Coupling

Product Description

   Sucker rod coupling is used to connect two sucker rods. Spray metal SM sucker rod couplings are better in anti-corrosion than common sucker rod couplings.  Slim hole and full size couplings are available.

Class T coupling is using AISI 5140 to manufacture.The coupling is coated using phosphate chemical treatment or black oxide on customer's request.For Class SM coupling, the spray metal is a specification hardening process and is applied on the base metal.

The couplings are available in full size, slim hole and over size.Also, combination couplings are available for different diameters (sub-coupling) for both Class T and Class SM couplings.
