What does a compression coupling typically allow in terms of joint performance?

A compression coupling is designed to allow moderate deflection, which means it can accommodate some level of misalignment or movement between two connected pipes or tubing. This characteristic is particularly important in systems where thermal expansion, contraction, or vibration may occur, as it helps to maintain the integrity of the connection while also allowing for slight adjustments without compromising the pipe system's overall performance.

This moderate deflection capability balances the need for flexibility with the requirement for a secure connection, making it suitable for various utilities applications where movement might occur due to factors such as ground shifts or temperature changes. By allowing moderate deflection, the compression coupling helps to minimize stress on the piping system, preventing potential failures or leaks.
