Where should pipe joint compound be applied?

• A. On both male and female threads
• B. Only on the female threads
• C. Only on the male threads
• D. On the threads where the joint is to be connected

Answer: (C)

Applying pipe joint compound correctly is essential for ensuring a leak-free connection between threaded pipes. The appropriate method is to apply the joint compound only to the male threads. By doing this, the compound helps to fill in the gaps and imperfections on the surface of the threads, creating a seal when the male threads are screwed into the female threads. Using joint compound on just the male threads can also prevent excess buildup that might otherwise interfere with the connection or sealing effectiveness. Moreover, if the female threads are coated with compound, it could lead to difficulties during assembly and possibly impair the integrity of the joint over time. In plumbing practice, it's crucial to follow correct procedures for applying joint compound, as improper application can lead to leaks, which could result in water damage and additional work to repair. Therefore, focusing on the male threads ensures that the connection is secure and properly sealed without unnecessary complications.
