The Importance of Female Threaded Coupling Parts

What is the purpose of the free-turning ring in a female threaded coupling?

A. Secure and tight coupling

B. Thread cutting

C. Starting point of the thread

D. Indication of full thread

Answer:

The correct answer is A. Secure and tight coupling.

Female threaded couplings consist of various parts that play crucial roles in ensuring secure connections. One of these parts is the free-turning ring, also known as the Swivel, on which the threads are cut. This component allows for tight coupling by creating a secure connection between two pieces.

The Shank, Higbee cut, and Higbee indicator are other important parts of a female threaded coupling. The Shank refers to the main body of the fitting, providing structural support. The Higbee cut is a notch that indicates the starting point of the thread, while the Higbee indicator marks the beginning of the full thread.

Understanding the different parts of a female threaded coupling is essential for proper installation and maintenance to ensure reliable and secure connections in various applications.
