Reflecting on Female Threaded Couplings

What is the purpose of the swivel in a female threaded coupling?

A. To start the threading process

B. To allow the tightening or loosening of the connection

C. To indicate the start of threading

D. To cut the threads

The purpose of the swivel in a female threaded coupling is:

B. To allow the tightening or loosening of the connection

When reflecting on female threaded couplings, it is important to understand the role of the swivel component. The swivel is the free-turning ring on which the threads are cut in a female threaded coupling.

Unlike the shank, which is the straight part of the coupling, the swivel allows for easy rotation to tighten or loosen the threaded connection. This flexibility is essential for adjusting the coupling as needed during installation or maintenance.

While the Higbee cut and Higbee indicator assist in starting the threading process, it is the swivel that enables the actual movement and adjustment of the coupling. This highlights the importance of the swivel in the overall functionality of female threaded couplings.
