What should be checked if a fitting does not stop correctly during a threaded connection?

When a fitting does not stop correctly during a threaded connection, it is essential to check the quality of the thread. Thread quality directly affects how well two components will connect. If the threads are burring, cross-threaded, or damaged in any way, this could prevent the proper engagement and alignment required for a secure fitting. Quality threads are crucial for creating a tight seal and ensuring that the connection can withstand the intended pressure and environmental conditions.

The condition and precision of the threads must be verified because improper thread quality can lead to leaks or fitting failures, which ultimately compromises the integrity of the overall system. Ensuring that the threads are clean, well-defined, and free of defects is necessary for successful threaded connections.
