What is the essential purpose of a jointing compound in plumbing systems?

The essential purpose of a jointing compound in plumbing systems is to seal male threads. This compound is specifically formulated to fill gaps and provide a watertight seal between threaded connections, preventing leaks that can occur at joints. When applied to threads, the jointing compound creates a barrier that not only enhances the tightness of the connection but also helps to lubricate the threads during assembly, making it easier to tighten them properly.

This sealing capability is crucial in plumbing applications because even a small leak can lead to significant water loss, potential damage to structures, or the development of moisture-related issues. By ensuring that connections are secure and sealed, the jointing compound contributes to the overall integrity and reliability of the plumbing system.
