The Deflection-proof and Abrasion-proof Sucker Rod Coupling, ***** The Spray Metal 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 in a high temperature. It can’t only protect itself but also the rod, preventing and slowing down the wear. The coupling has many types and sizes, and it is made of good quality using steel alloy AISI ***0. It has three functions: wear proof, corrosion-resisting and reducing the friction.
