What kind of connectors must be installed following the manufacturer's instructions?

Flexible connectors must be installed following the manufacturer's instructions because they are designed to accommodate movement and thermal expansion in various systems, such as gas and liquid transfer. These connectors often have specific installation guidelines to ensure safety and optimal performance, including the correct orientation, torque specifications, and attachment methods.

Proper installation is crucial for flexible connectors as improper handling can lead to leaks or failure under pressure, which poses significant safety risks in environments using propane or other gases. Since these connections are often subject to varying conditions compared to metal or rigid connectors, adherence to manufacturer guidelines helps ensure the longevity and effectiveness of the installation. The situation surrounding the use and installation of flexible connectors highlights the importance of understanding and following the particular instructions provided by manufacturers to mitigate risks and guarantee reliability in gas applications.
