API sucker rod coupling

 

Two types of coupling are available which meet API Specifications: Regular API Class T Coupling and Spray Metal Coupling for anti corrosion. The Deflection-proof and Abrasion-proof Sucker Rod Coupling is my special product, which is processed with some special technology, coated a layer of abrasion-proof, wear-proof and lessening friction coat. It can not only protect itself but also the rod, preventing and slowing down the wear.
