Coupling (level T): The level T coupling produced by the company contains full-scale coupling and slim-hole coupling, and that has two wrenching heads or none on its encircle. Both couplings are made from high-quality structural steel. Its tensile strength is no less than 655Mpa, and after heat treatment its harness isHRa56-62.It has better resistance against corrosion and abrasion. Level T coupling is used for connecting pumping rods of same specifications.
