Jointing compound is primarily used on which part of the plumbing process?

Jointing compound is primarily used on threaded pipes to create a seal between connections. When threads are cut into pipes and fittings, they form a mechanical connection that can sometimes leave small gaps. The jointing compound fills these gaps, preventing leaks by providing a watertight seal. Application of the jointing compound is typically done on the male threads, as this is where the sealing action is needed when the male connection is threaded into the female connection.

Using the jointing compound solely on male connections is standard practice because it ensures a complete seal when they engage with the female threads. The correct application enhances the integrity of the joint and minimizes the risk of leakage over time, especially in high-pressure systems where any small leak can lead to significant issues.

In this context, while it is important to use jointing compounds appropriately in plumbing, the focus is on its critical role in ensuring the effectiveness of threaded connections, especially on the male sides where the threads are exposed and require sealing.
