Description

Sucker Rod Couplings

The tubing coupling has become widely utilized in diverse applications such as supplying cold and hot water, heating systems, fire protection, medicinal gas, and industrial petroleum pipeline systems. It has effectively substituted welding fittings in multiple regions including Europe, Asia, America, Australia, and other parts of the world.

A precision-machined metal coupling that conforms to API 11B specifications.

Specifications for sucker rod couplings include:

- Material: High-quality carbon steel, which conforms to API 11B specifications.

- Threads: Premium API cold-formed roll threads.

- Coating: Available in either black oxide or zinc-phosphate coating, providing improved corrosion resistance and lubricity.
